1.1 Geoscience Education
Roberto Greco greco@ige.unicamp.br (Brazil), Chris King (UK)

Roberto Greco, a Professor at the University of Campinas (Brazil), lectures on introductory teaching of geoscience for geology and geography students and a teaching on Geoscience Education for future geography teachers. Since 2018, he is Chair, of the International Geoscience Education Organization (IGEO). He leads the Geoscience and Society research group that carries out research in education and the communication of geoscience.

Chris King is Chair of the International Union of Geological Sciences Commission on Geoscience Education (IUGS-COGE), Chair of the Education Committee of the European Geosciences Union (EGU) and Senior Officer of the International Geoscience Education Organisation (IGEO).

The focus of this symposium focuses on the processes that lead to better geoscience education.

The exponential increase of human population along with the dominant economical models and the technological applications of new scientific research are throwing up challenges that are new in human history.

The impacts of Homo sapiens on planet Earth are increasingly devastating.  Land occupation, mining, chemicals used in agriculture, pollution of air and waters are just some of the issues that are of concern for the future of our species. In daily life we are vulnerable to natural and human-induced disasters on a large scale so that people need to know how to mitigate, be resilient and adapt themselves.

It is urgent for politicians, business leaders, general stakeholders and citizens in general to give a serious thought to the grim situation that we face today. We need a new generation that looks at global issues with the systemic perspective of Earth System Science. Future generations must take into consideration the cycles and feedback processes that happen on planet Earth, the influence of the Solar system and the Universe through timespans and perspectives from historical to geological. Future generations should link the new advances in science in response to human needs in ethical ways.

Geoscience education is an interdisciplinary field of research that is devoted to studies of the processes that will lead to a better educated student community and an earth science-literate public. In this sub-theme we expect contributions from the new frontiers of research.

We expect to have following sessions under this symposium i) Geoscience education at school level, ii) Geoscience education in Higher Education, iii) Communicating geoscience to the public, iv) Technology in geoscience education, etc.

Keywords: Teacher training; geoscience education; environmental education; school teaching; primary and secondary

1.2 Geoscience Communication and Outreach
Iain Stewart istewart@plymouth.ac.uk (UK), Kirsten v. Elverfeldt (Austria), Eduardo de Mulder (The Netherlands), Courtney Jermyn (The Netherlands)

Iain Stewart is Professor of Geoscience Communication at the University of Plymouth, Director of its Sustainable Earth Institute and holds an UNESCO Chair in Geoscience and Society. He is an Executive Editor of the European Geosciences Union journal, Geoscience Communication.

Kirsten von Elverfeldt is associate professor at the Department of Geography and Regional Studies at the Alpen-Adria-Universität Klagenfurt (Austria). Her research interests are theoretical geomorphology, system theory and self-organization in the context of global environmental change. She is a spokeswoman of the Austrian Research Association on Geomorphology and Environmental Change, board member of the Austrian Geographical Association, and an Executive Editor of the European Geosciences Union journal, Geoscience Communication.

Eduardo de Mulder is an emeritus professor of Delft Technical University with a wide international network in the geosciences. Among others has been the President of the International Union of Geological Sciences (2000-2004), the Initiator and Executive Director of the UN proclaimed International Year of Planet Earth (2007-2010), and the Director of the Earth Science Matters Foundation (2011-2017).

Courtney Jermyn is the Director of the Earth Science Matters Foundation and a Senior Consultant at Sweco. She has over 14 years of employment experience in the geosciences, working in multidisciplinary and multinational teams on geotechnical and geological projects throughout the world.

As part of the broader vision of "geoscience for society", Earth scientists are increasingly expected to convey what they do and what they know to politicians and public. For this reason, there is a need for the Earth science community to be far more effective in engaging with issues of popular and political concern. Thus, in a time of “fake news” and a heightened public scrutiny and scepticism of science, the geosciences need fresh strategies of engagement. Those strategies require considerations of both the intended audience and the appropriate narrative framing, which in turn requires a framework for interdisciplinary research. In creating this interdisciplinary framework, it is vital to consider the role of issues such as transparency, ethics and diversity, not just as boxes to be ticked, but as essential elements in innovative and insightful communication.

This symposium invites contributions from those actively working on societal aspects of Earth science - climate change, natural disasters, geo-energy and geo-resources, engineering and environmental geology, and urban geoscience - to explore the challenges and opportunities of working at the public / geoscience interface and help establish an inclusive and effective communication of the science of our planet.

It also explores outreach activities at a national and international level, and the legacy of the IYPE. Outreach initiatives at national and international levels are critical for increasing awareness of the importance of geosciences in achieving a sustainable future for society.

Another goal of this symposium is to explore the use of Geoscience expression to create impact, awareness, and understanding of the Earth’s processes and history. Through art expression, story-telling and data integration, this symposium hopes to create an inspiring platform that showcases innovative methods of communicating geoscience to society.

Possible Sessions under this Symposium could be i) Communicating Geoscience for Society, ii) Geoscience outreach at national and international levels; and the IYPE legacy, iii) Bridging the Generation Gap - Transferring Geoscience knowledge across Senior and Young professionals, iv) Earth Science Through Art - Communicating through creative expression, v) Culture Geology.

Prof. Dolores Periera has worked extensively on the Heritage Stones of the world and as the Secretary General of the IUGS Sub commission on Heritage Stones. She is proactive in creating awareness of Heritage and the importance of the stones through time

Natural stones are the main material used in architectonic heritage. The session deals with natural stone types that have achieved important use and have been accorded significant recognition in human culture. The initiative through this sub-theme is to bring out the global heritage stone resource to the fore and to highlight its relevance. Its recognition will kindle public and policy-maker interest in stone-built heritage, encourage the use of local natural stone and ensure its availability for the maintenance of built-heritage and the quality of new buildings. This sub-theme is promoted by the newly recognized Heritage Stone Sub-commission (HSS), an IUGS Subcommission within the International Commission on Geoheritage (ICG). It encourages contributions on the proposed thematic issue: natural stones and heritage and their potential application and information on possible stones from all over the world. Contributions are also welcome on the importance of using original natural stones in the restoration and conservation of historical buildings, and other issues associated with natural stones and geoheritage, such as historical quarries and quarry landscape.

Keywords: Heritage Stone Resource, Architectonic Heritage, Cultures, Quarries, Uses

1.5 Geosciences, Art and Heritage
José Sellés-Martínez pepe@gl.fcen.uba.ar (Argentina), Tom Heldal (Norway), Mónica Álvarez del Buergo Ballester (Spain)

José Sellés-Martínez is a PhD in Geology, specialized in Structural Geology, and active in formal and non-formal education and outreach. Member of IGEO, AGA, AEPECT, etc. Was awarded the J. J. Nágera medal by the AGA for his contribution to the popularization of geological knowledge.

An intense and lasting relationship between Geosciences and Art predates the oldest stone-made works of art (like de Venus of Willendorf, the paintings in Lascaux Caves or the monuments in GobekliTepe). This Symposium aims to bring together geoscientists, art restorers, curators and also artists through their links to, and professional interest in, minerals and rocks in particular, and Geosciences in general. This will enable them to present, share and discuss their findings, products and proposals.

The interaction between Art and Geosciences is, at present, developing new facets and paths that include: a) Recognition, description and identification of geomaterials (natural and human-made), b) Assessment for their preservation and restoration, c) Use of geoscientific tools in the area or rural and urban archaeology (like remote sensing, geo radar and archaeomagnetism), d) Identification of quarries of building rocks in order to replace missing pieces, e) Identification of rock types and quarries to assess possible forgeries, and f) Need to identify the mineral composition of pigments to establish their epoch of production and provenance to help Art historians.

Meanwhile, artists and architects make use of geomaterials in new and different ways, not only as material with which to work but also include local geology and landscape as part of the work of art. This not only creates new links between geoscientists and artists but also opens new areas of interaction such as how these works of art will be conserved (or transformed by natural processes) with time.

Finally, Geosciences, Art and Heritage are just different and partial approaches to a more complex world and can be linked together to produce new and more effective ways of teaching and learning that cannot be dismissed if the need to have informed, cultivated and judicious citizens is recognized.

Keywords: Art, Geoscience, Education, Conservation, Restoration

Medical geology is a fast-growing multidisciplinary science, which aims at identifying harmful elements like arsenic, fluoride and metals in physical and chemical environments causing serious diseases among people living mostly in developing countries. Thus, interaction and communication are needed to seek solutions to better protect human health from toxic and other harmful elements. Contamination of surface water, groundwater and air result in serious ailments among poor children and other marginalized sections of rural and urban population of developing countries. In particular, people in the deltaic and alluvial plains of India, Pakistan, Bangladesh and many other countries are facing serious health problems because of consumption of unsafe surface and groundwater or vegetables grown using contaminated water. Participants are invited to present abstracts in this symposium to discuss geological and anthropogenic causes, mechanisms, impacts on human health and mitigation measures in the context of the afore-mentioned aspects.

Dr. Eduardo de Mulder is an emeritus professor of Delft Technical University with a wide international network in the geosciences. Among others has been the President of the International Union of Geological Sciences (2000-2004), the Initiator and Executive Director of the UN proclaimed International Year of Planet Earth (2007-2010), and the Director of the Earth Science Matters Foundation (2011-2017).

Earth science has relevance to society and human life in a range of diverse ways. Geoscientists play a vital role in ensuring resources for humankind, environmental protection etc. We need an integrated approach to the exploration and extraction of georesources (metals, minerals, oil, natural gas, ground water etc.). Besides exploitation of these must be carried out keeping in mind the needs of the communities and environmental impacts. These activities must be carried out in tune with environment protection laws. Developmental activities should be environmentally sound and sustainable and importance should be given to protect and conserve our environment. Communication and dialogue with community and the public are important in all these endeavours. Exploring the subsurface is relevant and important in urban planning and other contexts.

Humankind has to deal with geohazards – both natural and human-induced. Efforts must be made to predict them if possible, minimise the damage to human life and property, and bring about awareness among people. Capacity building must also be given priority.

In all these endeavours, international co-operation is important as the goal for humanity is common. The role of women geoscientists in societal development and their problems and prospects in the present day context must be examined.

Contributions are invited on all aspects of geoscience (the examples given above are not exhaustive) that have a direct and important bearing on society.

Possible Sessions under this Symposium are i) Mining in populated regions – Contemporary and future challenges, ii) Sustainability and International Cooperation, iii) Geohazards: Creating Social Awareness, Preparedness and Capacity-building for mitigating Geohazards (A session proposed by AGID), iv) Geoscientists and Environmental Protection, v) Role of Women Geoscientist in Natural Resources Development (A session proposed by AGID), vi) The science and politics of developing Africa’s mineral resources, vii) What Lies Beneath - Integrating subsurface and surface geoinformation to make effective planning and development decisions now to ensure society is future ready.

1.12 The roles of UNESCO, IGCP and IUGS in realizing the UN Sustainable Development Goals (Symposium proposed by UNESCO-IGCP-IUGS)
Ozlem Adiyaman Lopes o.adiyaman@unesco.org (France), Edmund Nickless (UK)

Dr. Ozlem Adiyaman Lopes is UNESCO, International geoscience programme specialist. He works for the UNESCO Natural Sciences Sector and is responsible for the implementation of the international collaboration projects and global initiatives related to the International Geoscience and Geoparks Programme (IGGP).

Dr. Edmund Nickless is IUGS Councillor (2016/2020), Chair, New Activities Strategic Implementation Committee. He was the Executive Secretary of the Geological Society of London from 1997/2015. Previously he held senior positions in BGS, the Science and Technology Secretariat of the Cabinet Office & the Natural Environment Research Council.

It is proposed to hold a series of sub-Symposia/ Sessions, each of, say, six solicited presentations under this umbrella title to report on the work of UNESCO, IGC and IUGS, RESTORE - Researching Social Theories, Resources, and the Environment. Developing an advanced understanding of the Earth’s fundamental processes and resources is essential to fulfil the United Nations 2030 Agenda for Sustainable Development. The International Geoscience Programme (IGCP) is the oldest and most successful example of scientific cooperation between a non-governmental organization – the International Union of Geological Sciences (IUGS) – and an intergovernmental organization – UNESCO. During almost 50 years, this programme has been the gateway to successful scientific careers in pioneering research for thousands of IGCP project scientists. Global society is facing critical decisions about how we use our planet and its resources. Our reliance on the Earth for water, energy and minerals significantly affects climate change, economic prosperity, environmental impact, and health and wellbeing. At current rates of consumption, and with a future reliant on technology, the range and volume of resources we use are constantly evolving. There is an urgent need for a wider discussion on how we will resource future generations in a socially sustainable way and without disadvantaging future generations: How do we as individuals value the discovery, extraction, use and disposal of resources? Do individuals understand the positive and negative consequences of using these resources? What is acceptable behavior and what is not – to whom, why and under what conditions? What are the implications of the uneven geographical distribution of Earth resources on local, regional and national communities? What ethical dilemmas play a role in the development of future resources? How should multinational companies in both the extractive and manufacturing sectors contribute to the debate? Under the UNESCO sub Symposium, we will hear about UNESCO’s earth sciences activities and work related to the SDGs and this sub Symposium will also include contribution o of past and present IGCP projects to the SDGs.

2.1 Hadean to Archean Earth: Geological, Geochemical, Geochronological, Geophysical, and Numerical Perspectives
Martin Whitehouse martin.whitehouse@nrm.se (Sweden), Kristoffer Szilas (Denmark)

Prof. Martin Whitehouse is an expert in the field of applications of radiogenic and stable isotopes to understand the earliest evolution of the Earth-Moon system and the origin and nature of early crusts of the Earth.

Dr. Kristoffer Szilas works on the petrology and geochemistry of Archaean rocks.  His research aims at modelling in order to better constrain the early Earth Systems.

Comprehensive studies involving geological, geochemical, geochronological, geophysical, and numerical perspectives of the Hadean to Archean Earth will provide an opportunity to evaluate the (i) conditions that prevailed, (ii) the processes involved, and (iii) trace the evolution. Composition of the primordial continents on the Earth that is opined to be similar to that of lunar anorthositic crust. Earth's Hadean continents were believed to have been destroyed and deeply subducted through strong mantle convection. The primordial continents with upper felsic and lower mafic KREEP rocks are supposedly lost from the Earth's surface by 4.0 Ga and presumably collapsed by subduction erosion and sunk into deep mantle. The Primitive continent-lake-atmosphere system in Hadean set the cradle of prebiotitic life on the Earth. The symposia will address issues related to all above-mentioned aspects of this time period .

Keywords: Hadean, Archaean, crustal evolution, geodynamics, early Earth systems

2.2 Archaean Biosphere and Ecosystem
Mukund Sharma mukund_sharma@bsip.res.in (India), Robert Riding (USA)

Mukund Sharma is interested in understanding the evolution of early life on the Earth. His endeavors are targeted on Archaean and Proterozoic rocks to find evidence of early life early diversification prokaryotic metabolisms, radiation of eukaryotic forms and large complex megascopic remains

Robert E. Riding is an expert on microbial carbonates in earth history. His research investigates how algal and bacterial carbonates reflect long-term changes in major factors such as atmospheric composition, climate, sea-level, and seawater chemistry. He has worked on stromatolites and the development of ‘oxygen oases’ in Archean marine carbonates.

The Archaean Eon was an interval of fundamental interdependent changes in the evolution of the lithosphere, hydrosphere, atmosphere and life. Key biosphere developments include early physical evidence for life, both microfossils and macrofossils, and for significant biogeochemical interactions involving microbial metabolisms, redox changes, and marine and atmospheric oxygenation. Physical and chemical signatures of the origins and early development of life, and of how life processes transformed marine, non-marine and terrestrial environments, are entombed in Archaean sediments. These questions attract researchers from diverse fields worldwide to collaborate in deciphering the chronology and implications of Archaean ecosystem development and its complex environmental context. This research, involving multiple proxies and a wide range of expertise, requires a unified approach to critically evaluate the evidence and gain integrated insights into its implications and significance. These changes during the Archaean set the scene for the evolution of life and earth surface environments for the remainder of Earth history, and provide a wide range of fertile and rapidly advancing areas for global research.

2.3 Origin and evolution of the Crust-Mantle reservoirs during the Hadean to Archean.
Rajneesh Bhutani rbhutani@gmail.com (India), J S Ray (India)

Rajneesh Bhutani utilizes the tools of isotopes and elemental chemistry to understand the evolution of crust-mantle system through geological time in different tectonic settings.
J S Ray is an isotope geochemist, who uses stable and radiogenic isotopes and trace elements to understand mantle processes and its chemical evolution through time since Hadean.

The unique TTG-greenstone rock association in the Archean terranes all over the globe warrants to invoke Solid-Earth processes which are different from the post-Archean period. The preserved rock-record of Archean period is built on the legacy of the Hadean crust-mantle system. However, this legacy can only be deciphered through the indirect elemental and isotopic evidences as the Hadean rock-record is not preserved. This calls for untangling of the record which is complicated due to the superimposition of the post-Archean geological processes.
Recent studies using the short-lived isotope-systems such as 146Sm-142Nd have suggested stagnant lid-mantle interaction during the early Earth history. The TTGs are also likely originated by melting of the hydrous basalts not related to the Plate- Tectonics. We also have evidences to indicate that the mantle was chemically not as homogenous during the early history of the Earth as was believed earlier.
It is, therefore, important to retrieve more information about the mantle-crust system during the Hadean-Archean to understand the underlying tectonic processes and also to understand the pathways that led to the formation of the modern crust-mantle reservoirs.

3.2 Proterozoic Orogeny and Sedimentary Basins
Nick MW Roberts nickmwroberts@gmail.com, nirob@bgs.ac.uk (UK)

Nick MW Roberts has worked on Zircon geochronology, Monazite petrochronology and Supercontinent, Arc magmatism

Establishing the relation between orogeny and sedimentation is one of the most challenging endeavours in Proterozoic geology. Sedimentary successions involved in Paleoproterozoic orogenesis and undeformed successions span over the time-scale during the entire Boring Billion (1.78 to 0.85 Ga) are considered as most diverse and a storehouse of clues to Proterozoic evolution of oceans, atmosphere and life. The symposia will address conventional, recent and novel approaches towards high-precision geochronometry of Proterozoic sedimentary successions, developing novel geochronological methodologies and dating Proterozoic mineralization.

Although similarities between depositional processes and products on basin-filling and evolution appear to have enjoyed great uniformity throughout the sedimentary rock record, a noticeable distinction exists in the rates and intensities of a broad range of geological processes in the Precambrian epoch. Periodic elevated global sea level, aggressive weathering regime at elevated temperature, humid paleoclimate and absence of land plant mark Proterozoic continental sedimentation. In shallow marine set up, biological mediation of chemical sedimentation dominated by microbial biota.
Also, a global stratigraphic database for the Proterozoic Eon will allow ready correlation of rock units and tectonic settings across the world’s cratons. The symposia willl strive to address all such issues of the Proterozoic Earth.

3.4 Proterozoic Ocean; Chemistry and Oxygenation
Partha Pratim Chakraborty parthageology@gmail.com (India)

Partha Chakraborty is a Precambrian sedimentologist who has worked on Proterozoic ocean chemistry and oxygenation

The Proterozoic Eon marks the transition from an anoxic Archean to oxic Phanerozoic ocean –atmosphere system. Although oxygenation of deep ocean began at C. 1.8 Ga, recent studies on biomarkers of sulfur bacteria, molybdenum, sulfur and chromium isotope compositions of black shales, pyrites and ironstones strongly advocate that despite oxygenation of shallow ocean, the deep ocean remained largely in sulfidic-anoxic state throughout the Mesoproterozoic and parts of the Neoproterozoic period until the pO2approached near modern level after c. 1Ga. This symposium will explore various proxies of Proterozoic ocean chemistry and oxygenation and their validity in local/global scale.

Keywords: Proterozoic, Ocean, Oxygenation, Chemistry

3.5 Proterozoic atmosphere and Expressions of Life
Joydip Mukhopadhyay Joydip17@gmail.com (India)

Starting from Great Oxidation Event (GOE), increase of oxygen pressure through the Proterozoic time remains a subject of discussion. It is believed that atmospheric oxygen levels rose twice in the Proterozoic Eon, between 2.47 and 2.32 Ga and after 0.8 Ga. The two billion years’ delay in build-up of oxygen pressure in the sea and air up to modern level is tied with life in cause-effect relation. Alternatively, views are also expressed that appearance and diversification of life may be linked with genetic and /or developmental innovation in the biosphere and independent of any environmental control. The symposium will explore all aspects of complex relationship between life and atmosphere/ hydrosphere oxidation.

3.6 Proterozoic Geodynamics and Subcontinental Lithosphere (SCLM) Evolution from Geochemical Evolution of Magmatism Over Time
Peng Peng  pengpengwj@mail.iggcas.ac.cn (China)

Peng Peng has worked on SIMS U-Pb and Mafic dykes
The response to the high heat flow during Paleoproterozoic time had resulted in intraplate mafic magmatism manifested in emplacement of several continental-scale dyke swarms, large mafic-ultramafic layered complexes and alkaline ultramafic dykes and rocks of the carbonatite-kimberlite and lamprophyric clans. Although volumetrically low, the detailed study of their petrology, geochronology and geochemistry, and additionally from the entrained xenoliths of a wide petrologic range, has revealed a wealth of information on the nature and evolution of the Subcontinental Lithospheric Mantle (SCLM), which otherwise would have remained less known. This Symposium would focus on recent advances in our understanding the SCLM evolution and also bring together specific high quality geochemical and isotopic information on the host and xenoliths that would constrain older Archean-aged geodynamic events. Furthermore, several felsic granitoid rocks, termed as anorogenic types, have been recorded from cratons that would imply the role of mantle heating in theirgeneration. The study and documentation of these have provided clues to the existence paleo plumes and the attendant crust-mantle interaction.

In this symposium members of IGCP 648 (Supercontinent Cycles and Global Geodynamics, 2015–2019) and other researchers will present and discuss their latest progresses in the studies of supercontinent cycles and the geodynamic driving forces. It will cover a wide range of disciplines including the reconstruction of supercontinent evolution and global animations through time, paleomagnetism, orogenic and basin records of supercontinent cycles, tectonic processes related to supercontinent cycles, updates in the global databases of geotectonics, palaeomagnetism, mineral deposits, and mantle plume events and how to apply them to supercontinent studies, and geodynamic modelling of deep earth processes that drive the supercontinent cycles.

4.2 Extremes of Metamorphism during the Supercontinent Cycle
Dr. Chris Clark  c.clark@curtin.edu.au (Australia)

Amalgamation of various crustal blocks to form supercontinents and their subsequent break-up are continental scale cyclic events driven by extreme energy flow within asthenospheric mantle, reaching up to the core – mantle boundary. An Unusually high magnitude of stress caused during the process results in extreme metamorphic conditions that are significantly distinct from those related to normal pressure- temperature rise during regional metamorphism. Therefore, the extreme metamorphism associated with supercontinent cycles needs special attention for a better understanding of the process of supercontinent cycles. This symposium would focus on different aspects of such extreme P -T conditions and fluid flow associated with supercontinent cycle.

4.3 Sedimentary records and Correlation of Supercontinent Crustal blocks
Dr. Wei Wang wwz@cug.cn (China), Dr. Christopher Spencer (Australia)

The formation and evolution of sedimentary basins are directly linked to assembly and breakup of supercontinents and in particular, the paleogeographic position of potential source regions. Sedimentary fills and bounding tectonic structures of rift-related basins can provide useful information about the changes in sediment supply, growth to death of normal faults and more importantly the early rifting of continents during supercontinent break-up. Sedimentology, sequences stratigraphy and single grained geochronology and geochemistry of coeval basins developed during the assembly and break-up of supercontinents have been widely used in paleogeographic reconstructions. In this symposium, coeval sedimentary basins in different continents/blocks/terranes will be discussed to delineate the relationship between sedimentation and tectonism and potential link to the configuration of the supercontinents.

Rifted margin segments feature a large structural variety in terms of general architecture, distribution of surface strain, crustal and lithospheric thinning in time and space, as well as the amount of sedimentation, magmatism and serpentinisation. It is clear that rift evolution is governed by the interplay of rheological configuration, tectonic inheritance, melting tectono-magmatic interaction, rift velocity, extension obliquity as well as surface processes and climate interaction, but the relative importance of these controls differs between individual margins. This symposium will address new data sets and methodologies that advance our understanding about the structure and dynamics of rift margin formation.

Dr. Jody Webster works in School of Geosciences, Geocoastal Research Group, Research interests include coral reef and carbonate platform systems, both modern and ancient, and their associated sedimentary systems.
Carbonate sediments mainly form in the shallow water realms along the low latitude shelves of oceans, but also are important elements of some high latitude continental margins. Whereas the basic understanding of these systems has been established several decades ago, marine geological research such as high-resolution seafloor mapping, high resolution seismic acquisition, and sediment sampling has added considerable knowledge regarding the sedimentary dynamics and stratigraphy of these deposits. In particular, processes influencing their slope and adjacent basin can now be investigated in great detail. This symposium aims to bring together carbonate sedimentologists and stratigraphers working in modern and ancient carbonates to discuss about the recent developments in carbonate sedimentology. Aspects such as dynamics at slopes of carbonate shelves, past environmental changes in carbonates, and carbonate sediment in source to sink system will be in the focus of this symposium.

Selvaraj Kandasamy is specialised in sediment geochemistry, applying geochemical and isotopic data/proxies to investigate elemental cycles and earth surface processes and their link with Earth’s climate on different timescales.

Prof. Dr. Shouye Yang Professor at Tongji University, China. Research interests: (i). Sediment geochemistry of major rivers and marginal seas in East Asia with emphases on sediment source-to-sink study; (ii) Quaternary geology and paleoenvironmental changes in East China and marginal seas; (iii) Weathering processes in the drainage basins and chemical fluxes into East Asian marginal seas.

Global continental margins, including the continental shelf, slope and rise, occupy ca. 21% of the total oceanic area. Nonetheless, these regions contain the majority of land-derived sediments and thus preserve ancient land climate connection linkages in the ocean margins facilitating the reconstruction of continental scale climate. Terrigenous sediments have undergone differential rates of earth surface processes and other elemental exchanges between and among atmosphere, lithosphere and biosphere on diverse timescales prior to supplying to the ocean margins. They contain a variety of inorganic and organic elements and their isotopes; all of them carry precise signals of continental scale processes, which are mostly climate-driven. Given the importance of margin sediments to rebuild continental processes, the symposium invites abstracts focusing on highly resolved sedimentary records of ocean margins around the Globe with a special emphasis on the Indo-Pacific margin.

Dr. Shyam Chand is a seismic expert in gas hydrate and worked extensively on the gas hydrate system in the Arctic Gas Hydrate, Environment and Climate (CAGE)

Dr. Priyank Jaiswal is a seismic expert in gas hydrate and worked extensively on the gas hydrate system in the Gulf of Mexico, USA.

Hydrocarbon deposits of economic importance have been found in the continental margins of several nations. This is encouraging and invites infrastructural development. However, this also requires that geo-hazards along the continental margins be investigated thoroughly to prevent loss of lives, damages to properties and catastrophic changes to the natural environments. Gas hydrate in particular can pose a significant threat to the sediment strength and stability along the margins. A detailed study of the margins using cutting edge geophysical tools for understanding gas hydrate and free gas system dynamics is necessary for long-term energy and sub-sea infrastructure planning. In this session, we would like to invite abstracts from the user community involved in the gas hydrate research with special emphasis on the geohazard potential of the gas hydrate destabilization.

Dr. Ghosh is Associate Professor at Bose Institute, Kolkata. Expert in microbiology. Currently working on microbial sulfur metabolism, and the microbiological processes of the oxygen minimum zone, off the west coast of India.

Perennial oxygen minimum zones (POMZs), as well as hypoxic coastal regions (transient OMZs) in the marine realms, are characterized by remarkable depletion in dissolved oxygen concentrations attributed to high biological productivity and respiration rate, coupled with poor O2 replenishment by oxygenated water masses. The POMZs occur within a water depth ranging from 200-1200 mbsl. Currently, POMZs are most widespread in the eastern Pacific, off the western coast of continents, and the northern Indian Ocean. Biogeochemical processes in the water columns and sediments of POMZs and TOMZs differ remarkably from those of the ambient oxic marine realms. Several reports on the expansion of OMZs and a consequential threat to marine life, especially fisheries, have augmented research interest in both water columns and paleo-records of OMZs. Global rock records are dotted with tell-tale signatures of remarkable oxygen-depletion phases within marine realms, right from the Proterozoic. Oxygen-depletions in the past have not only caused significant alterations in the global cycling of iron, carbon, sulfur, nitrogen and redox-sensitive elements but also impacted benthic biodiversity within and beyond the OMZs. In this way, through the geological past, marine OMZs have played a central role in the spatiotemporal delineation of benthic biogeochemistry across the global ocean. With an aim at augmenting holistic understanding of the pasts and presents of marine OMZs, this symposium invites abstracts on sedimentary biogeochemistry and paleo-records, as well as aquatic geochemistry and geobiology, of global OMZs.

The ocean floor and the marine environment are invaluable assents. It encompasses important geological and geomorphological structures, provides mineral and energy resources, and provides habitats for numerous species important for our environment as they should contribute to sustain global biogeochemical cycles. Thus data and information from the oceanic environment help keeping the balance between usage of the oceanic mineral/energy resources and the environment, are crucial to understand future developments and possibilities and provide a sound base for future generations to benefit. Digital data sets and digital maps are immense facilitators for international cross-boundary understanding of the Earth and provide the base for future applications such as mapping potential gas hydrate fields as a source for future exploration or mapping of marine habitats for constructing coastal management systems to keep sustainable marine resources and environments for future generations. Nevertheless, the ocean floor is investigated in much less detail than the land areas and mapping methods, mainly geophysical ones are a key for marine mapping campaigns. This session will offer multidisciplinary R & D contributions on geology and geophysics, and also bathymetric and biologic aspects, towards mapping methods, data sampling and acquisition, data analysis and their results, and innovative ways of data access. It also aims to present the actual development of processes to harmonize and integrate marine data across EEZ boundaries.

Prof. Nigel Hughes  nigel.hughes@ucr.edu (USA), Prof. Asish R. Basu (USA)

Dr. Hughes is professor of the Geology at the University of California, Riverside, USA.

Events related to the open and close of the Palaeozoic Era mark major transitions in the trajectory of Earth-Life interaction. The symposium will explore recent discoveries made worldwide that relate to these critical intervals, with an emphasis on studies that combine insights from multiple datasets and approaches, including geochemistry, isotope chemostratigraphy, paleobiology, sedimentology, petrology, and geochronology. As the Indian subcontinent has good records of both these transitions, we particularly encourage perspectives related to tectonomagmatic events associated with the peri-Gondwana margin at these critical times.

The possible sessions under this Symposium are i) The opening of an era: Precambrian-Cambrian boundary events and their aftermath, biotic turnover, and palaeogeographical evolution, ii) At the close: Critical events, Mass Extinction and Evolution of Biosphere

Keywords: Neoproterozoic, Cambrian, transition, paleobiogeography, bioevents

Prof. Gerta Keller is a Professor in Geology. She is one of the foremost worker on this theme.

Prof. N. Malarkod is a Professor in Geology working on this theme on Indian sediments.

Extinction events are important factors in the history of life on Earth, and many studies suggest catastrophic causes for at least some major mass extinctions. Two types of catastrophic event have been invoked: major impacts by asteroids or comets and episodes of continental flood basalt volcanism. Of the five major mass extinctions in Earth’s history, only the Cretaceous–Tertiary (K–T) mass extinction has been positively linked to an asteroid impact/ continental flood basalts (CFB), Over the past decade continental flood basalts (CFB) have been correlated with most major mass extinctions leading to suggest that this may be the general cause of mass extinctions. The symposium will cover various aspects on Volcanism and its role in Mass extinction and Paleobiodiversity and the key note addresses are arranged besides technical sessions.

The possible sessions under this Symposium are i) Marine Records, ii) Terrestrial Records

6.3 Cenozoic Paleoclimate and Ecosystem
Prof. Robert Spicer r.a.spicer@open.ac.uk, Torsten Utescher (Germany)

Robert Spicer’s research focuses on the Quantitative reconstruction of Paleogene and Neogene climate based on CLAMP (Climate leaf analysis).

Torsten Utescher is one of the founder member of NECLIME (Neogene climate evolution of Eurasia) His work involves quantitative reconstruction of Neogene climate based on Coexistence analysis of plants.

The global climate during the Cenozoic shows a general cooling trend with short abrupt warming periods as revealed by the marine isotopic records. The response time of marine water is always greater than the free air mass on the land surface because of the high specific heat capacity of water. This creates the disparity between land and marine reconstructed palaeoclimate dataset. The quantitative climate reconstruction during the Paleogene and the Neogene based on the biotic proxies are considered as most reliable because they are free from the diagenetic effect and their response time are also very quick. The two techniques such as CLAMP (climate leaf analysis multivariate program) and CA (Co-existence Approach) have been widely used for quantitative estimation of palaeoclimate during the Paleogene and the Neogene. The two aforesaid methodologies have been successfully used in the quantitative reconstruction of land palaeoclimate during the Paleogene and the Neogene climate. The biota during the extreme warming events during the Paleogene also affected severely which can be clearly observed in the floral turnover during the PETM. The symposium invites contributions in this regard.

The possible sessions under this Symposium are i) Quantitative reconstruction of the Paleogene and the Neogene climate and biotic turnover during the Paleogene warming, ii) Seasonal extremes during Cenozoic and Quaternary, iii) Primate Evolution and climate change.

Dr. Uma Ramakrishnan is an Associate Professor, National Centre for Biological Sciences, Bangalore, India

Past geodynamic and climatic events have majorly influenced speciation and extinction of biota. Inferring rates of speciation and extinction of biota in response to these historical processes over geological time scales is fundamental to understand diversification of species and biodiversity evolution in deep times. Modern synergized paleobiogeographic approaches will involve integration of fossil data with molecular phylogenetics to understand the evolutionary pattern in deep geological times. In recent years, it has been realized that molecular clocks used in molecular phylogenetics must be calibrated with reliable fossil-data to ascertain when groups and clades of organisms appeared. This symposium invites studies which used fossils and molecular phylogenetic approaches to reveal biogeographic pattern and global diversification of biota.

The possible sessions under this symposium are i) Biogeography of Angiosperms, ii) Reconstructing the Evolutionary History of species using Fossil and Molecular Biology approach

Five major mass extinction events occurred during the Phanerozoic Eon following which major radiations of animals and plants took place.  What caused these extinction events, what were the major changes in the physical environments, what are the important chemical signatures left in the sedimentary record, what biotic groups were most affected and the biota recovered after extinction boundaries are some of the topics that can be covered under this heading.

7.4 Gondwana Sedimentation, Climate and Life
PK Singh prakashbhu@rediffmail.com (India), Saswati Bandyopadhyay (India), AK Singh (India)

Sedimentation in the Gondwanaland (South America, Africa, Antarctica, India, Australia, Madagascar) began with a glaciation event in the Upper Carboniferous followed by fluvio-lacustrine sedimentation. Marine pulses have also been recorded in the Permian sequences. The sedimentary history and life of these continents was controlled by the climate to a large extent. The symposium will address palaeoclimatic changes in the southern hemisphere at a time it was assembled into a single super-continent. In addition, extensive coal deposits during the Permian time will also be discussed including changes in continental vegetation prior to and after the Permian-Triassic mass extinction. Further, semitonid and lung fishes, labyrinthodont amphibians, rhynchosaurs, phytosaurs, aetosaurs, di-nosaurs, pterosaurs, rhynchocephalians, mammal-like reptiles and mammals were thriving during the time of Gondwana assembly. Abstracts are also invited on evolution of vertebrates, their intercontinental affinities and relevance in biozonation and intercontinental correlation.

7.5 Break-up of Gondwana,Evolution of Indian Ocean and Development of Marginal marine Basin
DK Pandeydhirendrap@hotmail.com (India)

Following the break-up of former Gondwanaland, marine seaways emerged between the constituent continents and marine sedimenta-tion took place in pericratonic areas. Evolution of these sedimentary basins, their tectonic setting, and depositional history, evolution and diversity of fauna and understanding the past biogeographic provinces are focus of this symposium.

7.6 Mesozoic Marine Revolutions - Sea Level Changes, Extreme Climates, Mesozoic Bioevents, Biotic Recoveries, & Correlation
B Haq haq@purdue.edu (USA)

End of the Triassic Period witnessed a major mass extinction event. Various causes, such as marine regression, volcanism and asteroid impact etc. are suggested as cause for this mass extinction but no consensus achieved so far. The Triassic Period also experienced greenhouse conditions with major faunal turnovers. Correlation of these events at the global scale is needed.
Following the end permian mass extinction, new forms occupied the empty ecological niches. In the marine realm, new primary producers like coccolithophorids, diatoms and dinoflagellates arrived on the horizon. Land vegetation changed from lycopod- sphenopsid dominated flora to gymnosperm and fern dominated flora and then to angiosperm dominated flora. Dinosaurs, birds, and mammals evolved during the Mesozoic Era. Late Jurassic-Early Cretaceous interval is an important period, which coincides with significant environmental fluctuations and elevated levels of extinctions in marine invertebrate fauna and faunal turnovers in low latitude shallow marine faunas and in marine and non-marine vertebrate faunas. These bioevents are the focus of this symposium.
Further, the Cretaceous Period is a classic example of a Greenhouse Earth with ice- free polar regions. There are extensive records of black shales in the ocean and chalk in epicontinental seas. Oceanic-anoxic events are known from the Tethys and Atlantic basins. Understanding these anoxic events is also focus of this symposium.

7.7 India’s Northward Flight, Closing of Tethys, Rise of Himalaya, Biological Evolution
V C Thakur thakurvc12@gmail.com (India)

Following its rapid northward journey India collided with Asia in the Early Paleogene, which led to the rise of the Himalayan mountain chain. During this collision process, many tectonic and geomorphic features got expressed in the Trans-Himalayan region. Also, following the rise of Himalaya, weathering and erosion of rocks brought large quantities of sediments into the foreland basin. This was further accentuated by the intensification of Indian Summer Monsoon and the interplay of tectonics and climate. This symposium will address the role of tectonics and climate in shaping the geomorphol-ogy of the Himalayan frontal belt.

7.8 Paleogene Hyperthermal events––Sedimentologic, Geochemical & Biotic Responses
Vandana Prasad prasad.van@gmail.com (India)

Paleocene-Eocene Thermal Maximum (PETM) event is one of the greenhouse states that the Earth passed through during its geologi-cal past. During PETM, the average Earth’s surface temperature rose by 6-8°C and many organisms were severely affected by this rise in temperature. PETM also led to the diversification of mammalian fau-nas in the Northern Hemisphere and high latitude areas. The effects of this climatic perturbance in the the low latitude areas and Southern Hemisphere are focus of this symposium.

These inter-connected systems need better understanding to predict future sea-level contributions. This symposium invites abstracts related to theoretical, numerical, and observational works on dynamics and evolution of the polar ice sheets at both contemporary and geological timescales. Both regional and large-scale studies are welcome to develop a more comprehensive view of changing polar regions and their underlying causes, feedbacks and impacts.

Raja Ganeshram is a Professor and Chair of Geochemistry at the School of Geosciences, University of Edinburgh, UK. His research interest lies in studying the tropical Climate variability on glacial-interglacial to decadal time scales, and Global Change and Biogeochemistry of polar sea ice environments.

The polar and mid-latitudes play an important role in governing Earth’s climate. Recent climatological observations suggest that natural modes of climate variability in mid to high-latitudes such as Atlantic/Pacific (multi) decadal Oscillation (AMO, PDO) and North Atlantic Oscillation (NAO) as well as the Southern Annular Mode (SAM) can influence tropical climate including the South Asian, East Asian, American, and African monsoon systems on various timescales. Also, the tropics have been hypothesized to influence the high-latitude climate via oceanic and atmospheric pathways. However, observational time series are short and therefore cannot resolve low-frequency changes/events. It also raises the question as to whether such teleconnections were persistent in Earth history with fundamentally different climate states. Thus, the complex interaction between climate variability in the polar to mid-latitude regions and the tropics remains to be fully understood. This symposium invites contributions exploring the past climate variability of the mid-latitude and polar regions (including the Southern Ocean, Arctic Ocean, and North Atlantic Ocean) and the tropics (including the monsoons) on decadal, millennial, glacial-interglacial, and longer timescales from a proxy-data, modelling and data-model comparison perspective.

8.4 Southern Ocean – Past Global Linkages
Crosta Xavier xavier.crosta@u-bordeaux.fr (France), Luke Skinner (UK), Rahul Mohan (India)

Dr. Xavier Crosta is senior scientist at CNRS-EPOC, Université de Bordeaux, France. He is expert in diatom taxonomy, biogeochemistry and isotope chemistry to document Southern Ocean palaeo-oceanography and palaeo-productivity over the Pleistocene with a focus on the Holocene and last 2000 years.

Dr. Luke Skinner is a palaeoceanographer working at the University of Cambridge, in the United Kingdom. His research interests centre on the role of the ocean in the transport and cycling of heat and carbon on both short- and long timescales, in particular via changes in the ocean's large-scale overturning circulation.

Dr Rahul Mohan is a Scientist at NCAOR, Goa, India. He has developed a group on Southern Ocean paleoclimatology with special emphasis on diatoms, coccolithophores and planktic foraminifera.
The Southern Ocean (SO) is an important oceanic hub for redistributing heat, fresh water, carbon and nutrients around the planet and hence plays a key part in the climate system. Deep mixing in the Antarctic Circumpolar Current (ACC) is a key component of the global large-scale overturning circulation (LSOC) as it constitutes an important return path for carbon and nutrients stored in the ocean interior to reach the surface. The SO thus plays a pivotal role in the partitioning of carbon between the ocean and the atmosphere. However, the full range of mechanisms by which the SO may influence the LSOC and global climate, in particular via the modulation of the upper and lower overturning cells and of the ‘warm-’ and ‘cold’ return routes for water entering the Atlantic, are still largely unknown.

The main objective of this symposium is to bring together experts from a range of disciplines (biology, earth sciences, chemistry, ocean processes) to better identify past oceanic bipolar teleconnections in relation to global LSOC dynamics over the Plio-Pleistocene and provide constraints on its future evolution in response to anthropogenic warming. Non-exhaustively, topics may cover the following aspects: past changes in the SO upwelling and latitudinal mean position of the Antarctic Circumpolar Current; the dynamic controls of circum-Antarctic deep ocean ventilation/overturning circulation during the past few million years; implications for the marine biogeochemical cycles of carbon and nutrients.

A. A. Mohamed Hatha has doctorate in environmental microbiology and is a Fulbright fellow. He works on emerging pathogens and its impact on coastal ecosystems. His research addresses issues with respect to Arctic being more hospitable to human pathogens in wake of warming.

Masaki Uchida was awarded doctorate from Hiroshima University and currently works on polar microbial ecology with special reference to terrestrial systems. He works on both the Arctic and Antarctic realms and is interested to compare and contrast the changes that are manifested at poles in wake of recent climate variability.

The Arctic is experiencing rapid changes with respect to climate and its impact on ecosystems. Though one can debate on the root causes, internal variabilities and other external forcing mechanisms, it is very explicit that the impact is negative and is of extreme concern. Many studies focus on changes in larger biota that is easily perceptible and well explained. The impacts on sub microscopic organisms are grossly overlooked, as is the case with any realm. Before we realize the potential adverse effects arising due to community level compositional changes, the microbes would have adapted and invaded to realms, which were previously not conducive to proliferate and exhibit virulence. Change in migratory patterns and variations arising due to change in host specificity could further thwart our understanding on health significant processes. There is an immense need to identify marker species and understand genetic cross talks conferring properties of adaptation, resistance and even probably evolution of new species of microbes. In this session, we invite abstracts on digitizing microbial communities and exploring genomes and transcriptomes to unravel the changes at diversity and functional level.

Under unabated warming, the marine-based parts of the Antarctic Ice Sheets have the potential to provide a major contribution to sea-level rise over the next centuries. Of the Antarctic Ice Sheets, the response of the East Antarctic Ice Sheet (EAIS) to future oceanic and atmospheric warming is hard to predict because the ice sheet covers a large area with bedrock topography characterized both by deep subglacial basins and by high, buried, mountain ranges. Improved understanding of processes, thresholds, rates and magnitudes of previous EAIS retreats is essential to improve predictions of future sea-level rise. This symposium aims to bring together results from past ice sheets, spanning from the last deglaciation to times in the past with elevated CO2 and temperatures. These studies can extend from the ice sheet interior to the deep sea. This symposium welcomes contributions from fields including glaciology, ice sheet modelling, sedimentology, paleo-limnology, marine geology and geophysics, among other.

Glacier mass balance, unlike the changes in length and area, is a direct method to ascertain the impact of climate change on the glaciers and establishes a linkage between glacier dynamics and climate change. The geological method of mass balance studies provides quantitative estimate of glacier loss at high temporal resolution, which is essential for understanding climate-glacier interaction processes and spatio- temporal variability of the glacier mass balance, even with only a small sample of observation points. The glaciological observations are complemented by results from the geodetic method to extend the mass balance measurements for better insights into the glacial dynamics. Recent advances, especially availability of precise laser altimetry data sets, Lidar and laser-derived DEMs acquired using UAVs, provide a new opportunity to assess glacier dynamics in otherwise inaccessible and rugged terrain. The symposium invites abstract on all above aspects of glacier mass balance.

Melt waters from glaciers provide much of the water supplies for agriculture and hydropower production. Sustained glacier retreats in response to climate warming and anthropocene will significantly reduce the contribution of glacier-melt to the streamflows in glaciated basins. The forecast of streamflows in glacier-fed streams thus requires an understanding of the process controlling glacier mass balance, glacier hydraulics, sediment dynamics and fluctuations in glacier geometry. Hazards associated with glaciers, largely controlled by glacial hydrology have necessitated the need for better understanding of glacial hydrology. Sudden bursting of glacier-dammed lakes and of water stored within glaciers – and mudflows associated with these events – has caused extensive damage in mountainous regions. This symposium invites abstracts on all above-mentioned issues.

Kireet Kumar, Scientist & I/C Director,
Research interests: Climate Change and glaciers
GBPIHED, Almora, India; 

Glaciers are sensitive and direct indicators of climate and its fluctuations. The dynamic behaviour of glaciers and its sensitivity to climate plays an important role in determining the time dependent evolution of mass balance and runoff changes in mountainous regions. Standard glacier parameters include mass balance and the glacier length determines the position of terminus (snout position) and annual difference between net gain (accumulation) and loss (ablation). Fluctuations in snow line/ Equilibrium line altitude, Equilibrium Line Altitude and accumulation area ratio of aa glacier provides an immediate response of glaciers to climate change. This symposium will address glacial parameters those can be used as indicators of temperature and precipitation variation at local and regional scale and inter alia provide a direct indication of the health of a glacier.

Cryosphere encompasses all the Earth's icy regions— including snow, glaciers and permafrost. The above-surface part of the cryosphere occupies around one sixth of the Earth's surface, and is located in places that are generally very remote, rugged, and in challenging climatic conditions. Cryosphere is therefore well suited to the use of remote sensing techniques, especially those operated from space borne platforms. The availability of ICESat, CryoSat and AMSR-E data has given boost to the cryospheric studies. This symposium will address recent advancements in remote sensing and image processing for climatic behaviour modeling from cryospheric measurements.

The Institute of Mathematical Sciences (CMI)

Understanding the stability and dynamics of glaciers is critical for predicting the future of glaciers. Glacier dynamics are driven by the interplay between the topography, temperature and basal conditions beneath the ice. Cryosphere monitoring and modelling approaches are closely interconnected thereby the data from monitoring systems are routinely used to calibrate and validate numerical glacier dynamics models. Glacier dynamics models relating temperature with glaciers terminus records coupled with high resolutions climate models have recently been used to assess changes in glacier mass balance and associated impacts under changing climate. This symposium will address informations available in past few decades from satellite and other monitoring systems together with the advancement in the computing hardware to understand complex behaviour of glaciers at fine spatial and temporal scales.

Oliver Nebel Oliver.Nebel@monash.edu (Australia), Nicholas Gardiner (Australia), Tim Johnson (Australia)

Tim Johnson's research has concentrated on the study of crystalline rocks from a variety of geodynamic settings and what these can tell us about fundamental processes on Earth. His expertise lies in metamorphic petrology, in particular the application of phase equilibria modelling using internally consistent thermodynamic data.
Tim Johnson has specific interests in the generation, segregation and migration of melt in the crust and upper mantle, the fundamental processes driving the evolution of the lithosphere. More recently his research has concentrated on early Earth processes, in particular in Archaean geodynamics and the generation and modification of Earth's first crust.
Advances in geochronology, thermochronology, petrochronology, and the application of various stable and radiogenic isotopic tracers, now provide an unprecedented toolkit for the temporal and geochemical resolution of the stages of orogeny. This symposia welcome contributions on orogens through time, from the assembly of Archaean cratons, through to modern active orogenic systems. High-precision dating techniques and proxies for prolonged geodynamic processes are welcome, as are applications of traditional isotope tracers and new analytical tools such as non-traditional stable isotopes.

Alan Collins is Director of the Centre for Tectonics, Resources and Exploration (TRaX).
The Proterozoic is a period when eukaryote cells evolved, the Earth’s climate radically fluctuated, the atmosphere and oceans became oxic and when the supercontinental pulse carved up landmasses, developed and closed oceanic gateways and vast mountain ranges—it is the aeon when the Earth became habitable. In this multi-disciplinary symposium, we are seeking submissions that unravel the geology of the orogens that record plate-interactions. Distribution and evolution of plates and plate tectonics through the Nuna/Columbia–Rodinia–Gondwana supercontinent cycle, to their effect on the evolving broader Earth System will also be discussed.

10.4 Secular Change in Magmatism and Metamorphism: the Fingerprints of Orogenesis
Tim Johnson Tim.Johnson@curtin.edu.au (Australia)

Tim Johnson's research has concentrated on the study of crystalline rocks from a variety of geodynamic settings and what these can tell us about fundamental processes on Earth. His expertise lies in metamorphic petrology, in particular the application of phase equilibria modelling using internally consistent thermodynamic data.
Tim Johnson has specific interests in the generation, segregation and migration of melt in the crust and upper mantle, the fundamental processes driving the evolution of the lithosphere. More recently his research has concentrated on early Earth processes, in particular in Archaean geodynamics and the generation and modification of Earth's first crust.
On the modern Earth, specific tectonic settings within orogenic belts are characterized by different styles of magmatism and metamorphism. These provide tectonic ‘fingerprints’, mainly chemical in the case of igneous rocks and thermal in the case of metamorphism, which permit constraints on the geotectonic setting of older rocks, where much of the supporting evidence may have been destroyed. How far back into deep geological time these tectonic fingerprints can be relied upon remains debated, as the evidence generally becomes circumstantial rather than direct. This symposium invites contributions from studies of magmatic and metamorphic rocks of any age with a view to assessing, improving and questioning their potential use as petrogenetic indicators within a broad range of orogenic settings.

After an 18-month postdoc at the NERC Isotope Geosciences Laboratory (UK), he joined the Department of Applied Geology at Curtin University, Australia in 2015 to commence a five year Curtin Early Career Research Fellowship.
The Himalayas represent one of the best modern laboratories to study the evolution of thermal structure of an orogen during the collision between two continental plates. Collision leads to crustal thickening, which in turn causes temperature changes in the lower and mid crust as a consequence of enhanced radiogenic heating, in places resulting in melting of crustal domains. The topography generated by collision is simultaneously moderated by erosion and extension. These processes influence the thermal evolution of the deep crust, manifested in the form of phenomena such as inverted metamorphism and leucogranite production. Pressure-temperature-deformation-time paths extracted from responsive lithologies provide insight into the orogen’s interior, and record the thermal evolution of the crust as orogeny progresses. This symposium intends to cover a broad range of topics related to the thermal evolution of the Himalayan orogen, including metamorphism, syn- to post- collisional magmatism and geochronology..

11.2 The Himalaya - Surface processes
George Mathew gmathew@iitb.ac.in (India)

George Mathew specializes in Quaternary geochronology, Thermochronology and active tectonics, and has been working on these aspects in the Arunachal Himalaya.

Erosion and exhumation are processes that are intimately related to orogeny. Erosion and neotectonic activity drives present-day uplift and exhuhmation of the Himalaya, leaving signatures in the form of geomorphic features such as incised gorges, undercut river valleys and terraces. Rates of such uplift can be constrained using a variety of thermochronological techniques. Enhanced erosion leads to a corresponding material influx into Himalayan rivers and streams, and the geochemistry of waters within the fluvial systems can serve as an efficient monitor of erosion rates. The rate at which erosion and denudation occur impact global climate, through processes including silicate weathering and burial of organic carbon, although the extent to which climate is so influenced is disputed. This symposium intends to discuss all erosional and exhumation processes including the sedimentary record, thermochronological constraints on uplift and exhumation rates, detrital mineral studies in Himalayan rivers and fluvial weathering chemistry and its ancilliary effects on climate.

11.3 Crustal Deformation of the Himalayas
Vineet Gahalaut vkgahalaut@yahoo.com (India)
The Himalayas represent an unrivalled case study for understanding the mechanisms of continent-continent collision. The classical model for creating the Himalayan orogen involves rapid northward movement of a fast moving Indian plate and subduction of the Tethys ocean, before the Indian continent finally collided with Eurasia. Shortening related to this convergence continues today, and the crustal deformation is primarily accommodated on a number of Himalayan discontinuities. Recent careful geodetic measurements confirmed that the total shortening is not limited to the Himalayan region, but is also accommodated within Tibet and the Indian peninsula. This symposium intends to discuss regional tectonics and geophysical studies relating to tectonic plates in the context of the Himalaya. We welcome results from geodetic studies of the deformation of the Indian and Eurasian plates, from seismological studies of recent and past Himalayan earthquakes.

His avid love of mountaineering morphed into a love of geology and mountain systems. He did an undergraduate degree in geology at Aberystwyth University in Wales and a PhD at the Open University studying the metamorphic sole of the Semail ophiolite in Oman. For the past 30 years he has studied the geology of the UAE/Oman ophiolite, Himalaya, Karakoram, Tibet, and Southeast Asia.
This symposium will cover the geological evolution of the entire Himalaya chain including Indus suture zone, Tethyan Himalaya, Great Himalayan metamorphic sequence (GHS), Lesser Himalaya (LH) fold-thrust belt and the Siwalik molasses basin. Processes to be covered include timing of the India-Asia collision, ophiolite obduction, island arcs within Tethys, pre- and post-collision sedimentary record, crustal shortening and structural evolution, metamorphic evolution, crustal melting and leucogranite formation.

11.5 Brittle vs Viscous Deformation in the Himalaya – Field to Experiments
Santanu Bose bose.santanu@gmail.com (India), Rodolpho Carosi (Italy)

Santanu Bose has worked extensively on numerical and analogue modelling of geological structures. He is currently actively involved in, and has published on models that are directly related to the Himalayan structures.

Rodolpho Carosi specialises in continental tectonics and has published extensively on Himalayan faults and shear zones.

The Himalaya is a natural laboratory for understanding orogenic processes. A unified theory of Himalayan evolution that links extreme topography with subsurface processes remains elusive. The two competing hypotheses, channel flow and wedge tectonics, provide alternative explanations for the development of the Greater Himalayan Sequence, both with respect to its exhumation and topography. None of these models give importance to the role played by the regionally occurring ductile fabrics (e.g. foliations), and their potential link with Himalayan thrusts (e.g., MCT, Ramgarh, and MBT). This symposium intends to examine the cause of varying pattern of deformation over spatial and temporal scales in the Himalayan belt. We invite new results that discuss the link between the regionally occurring ductile structures and brittle faulting, and the exhumation of the Greater Himalayan Sequence in the framework of Himalayan orogeny. The symposium will encompass field, experimental and numerical studies on the Himalaya, focusing largely on faults, shear zones and modelling studies.

Dr Dilek is a University Distinguished Professor at Miami University, with an expertise on tectonics, geochemistry and petrology. He has served as the Vice President of the USGS for a term. He has worked extensively on ophiolites in many orogenic belts and has published about 250 peer-reviewed papers and 28 books. See the attached CV.
Dr Windley is an Emeritus Professor at Leicester University. He has worked extensively in Phanerozoic and Precambrian orogenic belts and ophiolites around the world. He has published about 350 papers and a widely cited book, entitled “Evolving Continents”.
In this symposium, we will examine the ophiolite record of Supercontinent Gondwana and its continental derivatives, spanning the entire evolutionary spectrum from its assembly through accretionary and collisional tectonic events to its disassembly and dispersal through continental rifting, seafloor spreading and subduction mechanisms. Precambrian and Phanerozoic ophiolites in India, Africa-Arabia, South America, Antarctica, Australia, Central Europe and Iberia reveal significant geological evidence for the assembly and disassembly of Gondwana. We welcome contributions presenting new data and interpretations as well as refined models and overview of ophiolite occurrences in all these Gondwana-derived continents.  We envision this symposium as an interactive forum for the exchange of new concepts, models and data on the Gondwana geology with a focus on its ophiolite record

12.1 Deserts: Past and Present
Deepak M. Maurya dmmaurya@yahoo.com (India), Amal Kar (India)

Drs. Deepak Maurya and Amal Kar have extensive experience in working on modern and paleo-desert systems in Thar Desert.

Deserts are one of the most complex and fascinating ecosystems. Scientifically these are the ‘arid lands’, covering 20% of the global non-polar area, but accounting for only 6% of the world’s population. Yet, the high population growth rates in the arid areas, especially in the developing nations, have impacted the region’s scarce natural resources, especially soil and water, with risks of land degradation and atmospheric dust. This throws huge challenges to the geo-scientists for finding sustainable solutions to the emerging problems. Despite numerous in-depth studies during the last few decades, our geo-scientific knowledge on the desert’s past and present still needs improvement to address the emerging problems arising from excessive resource use. An understanding of the landscape response to past climates in quantitative terms may also be necessary to model the future landscape responses to climate change. This symposium invites abstracts on various aspects of deserts including

  • Antiquity of the deserts processes.
  • Interpreting the legacies of water, evaporites and placers for sustainable use.
  • Patterns of human and cultural response to past environmental changes.
  • Quantification of the present-day landscape processes: aeolian, fluvial and others.
  • Desertification – causes, preventive measures, and future needs.

Keywords: Arid land sedimentation, Chronology, paleoclimate, Desertification

12.2 Soil-Geomorphology and Landscape Evolution
Pankaj Srivastava pankajps@gmail.com (India), Peter Kühn (Germany)

Dr Pankaj Srivastava and Dr Peter Kuhn have worked and published extensively on evolution of Quaternary landscape using soil geomorphology in various type of climate and tectonic settings.

The intimate relationship of soils and landforms forms the sound basis for the use of soils in geological studies. The application of soils in geomorphic research is now a well-established approach because the history of any landscape evolution is intimately tied with the history of soil development. Increased application of this approach has brought a major change from the traditional historical approach to quantitative evaluation of the physical processes that act over different time scales ranging from 103 to 105 years. It is realized that the study of soil-chronosequences is the most valuable tool to infer the rates of soils and landscape evolution and to comprehend the soil-geomorphic processes that act over different time scales. In view of its tremendous application, soil-chronosequences developed across the landforms have become a potential tool for testing the pedological and geomorphic theories. This symposium intends to address soils, landforms, erosion, flooding, sedimentation, vegetation and land use to understand the soil-geomorphic in relation to changing climate during the Quaternary.

Keywords: Soil geomorphology, landscape evolution and Quaternary climate and tectonics

12.3 Mountain Landscape: Tectonics and Climate Feedbacks
Rasmus Theide rasmus.thiede@ifg.uni-kiel.de (Germany), Pradeep Srivastava (India), Manfred Strecker (Germany), Bodo Bookhaagen (Germany)

Drs Bodo Bookhagen and Rasmus Theide have worked extensively on exhumation, climate tectonic feedbacks and evolution of mountain chains like Himalaya.

Dr Pradeep Srivastava has developed model and chronology explaining climate forcing in widespread river valley aggradation and incision and evolution of riverine landscape of Himalaya.

The coupling between tectonics, surface processes and climate can fundamentally govern the dynamics of mountain belts and shapes it landscapes. A diverse range of geomorphic and sedimentary records, including longitudinal river profiles, fluvial terraces, downstream fining trends, growth strata, sediment provenance, sequence stratigraphy, and changing depositional environments provide first order constraints. The increasing integration of new methods for quantifying erosion rates and source-to-sink sediment transfer at a range of temporal and spatial scales with landscape evolution has significantly improved our understanding on rock exhumation, surface processes and erosion. This symposium aims to attract contributions that explore the relationship between surficial geomorphology, sediment dynamics and from active tectonics to plate boundary processes, including studies that link upper plate processes to deeper crustal structure. In particular, we encourage coupled catchment-basin studies that take advantage of numerical/physical modelling, geochemical tools for quantifying rates of surface processes and high resolution digital topographic and subsurface data. We also invite contributions that address the role of surface processes in modulating rates of deformation and tectonic style including plate boundary processes.>>

12.4 Glaciers: Past and Present
Aparna Shukla,aparna.shukla22@gmail.com (India), Manish Mehta (India), Dirk Scherler (Germany)

Dr Aparna Shukla and Dr Manish Mehta worked and published extensively on glacial processes, inventory and Paleoglaciation in NW and Garhwal Himalaya

Dr Dirk Scherler is modelling expert who has developed regional scenarios on glacial-climate responses in Himalaya and other places.
Mountain glaciers shape the Earth’s surface both at present and in the geological past. The extent and timing of Quaternary glaciations have an impact on the patterns of regional and global climate, which in turn affects carving mountainous topography. The linkages and interactions of varying climate and ice cover extents, with downstream fluvial systems, orogen-scale mass and force-balances is still poorly understood. Key challenges include the dating of glacial landforms and reconstructing glacial dynamics at 103-105-year timescales. New developments in the fields of Quaternary geochronologyhave provide unprecedented opportunities in upcoming years. At present, mountain glaciers across the world are important reservoirs of snow and ice that caters to the water demands of billions of people. Changing climate is resulting in widespread shrinkage of the cryosphere and climatic perturbations are significantly affecting the timing and magnitude of the water release. Precise quantification and monitoring of glacier changes are thus vital. Enhanced glacier melting is also promoting the formation of glacial lakes that, when catastrophically drain, pose significant risks to the downstream communities. This symposium invites abstracts on

  • Understanding glaciations across time and space.
  • Estimation of glacial ice reserves – methods and errors.
  • Glacier response to climate change and forcing factors.
  • Glacial and high altitude lakes – processes, status and hazard.
  • Glacial hydrology – climate change impacts

Keywords: Glacier, Climate change, Cryosphere, Quaternary, and Hydrology

12.5 Extreme Hydrological Event -Present and Past

The proposer has worked extensively on the extreme flood sequences and their chronology of western and Central India and has been an important member of Fluvial archive group (FLAG) of PAGES
Extreme hydrological events, those occur with significantly lower or higher magnitude and frequency than threshold values, pose severe risk to human safety, cause economic loss and are a threat to sustainable development. These events are unique or clustered in time and often change the landscape and related processes of a region. One important implication of climate change is the predicted increases in the frequency and intensity of extreme hydrological events, namely, droughts and floods. This symposium solicits presentations on multi- archival and interdisciplinary investigations on understanding extreme events, past and present, in various global regions. Also invited are deliberations on the response of human societies to such large scale impactive events.

13.1 Recent Advances in Near Surface Geophysics
Gerald Gabriel gerald.gabriel@leibniz-liag.de (Germany)

Gerald Gabriel: 1997 PhD TU Clausthal, since 1998 LIAG, since 2016 acting head of department ‘Seismics, Gravimetry, Magnetics’; lecturer at Leibniz Universität Hannover, associate editor ‘Near Surface Geophysics’

Near-surface geophysical exploration methods are particularly relevant with regard to exploration and use of the economically viable but also vulnerable subsurface, a task of high societal relevance. This covers a wide range of applications, for instance, the exploration of natural resources, geotechnical exploration, landscape evolution, and archaeology. Apart from manifold applications, urban regions are moving into the spotlight of near-surface investigations, due to their increased vulnerability, thus posing new challenges to the methods available. Simultaneously, the demands on the spatial resolution of the provided information, in particular of 3D structures and parameters, are steadily increasing; comprehensive understanding of the system requires innovative methods to monitor and even possibly forecast geological processes. These developments in acquisition technology must be accompanied by progress in the processing of the acquired data, in numerical modelling, and even in data management. This symposium aims to address all aspects related to near-surface geophysics studies.

Hitoshi Kawakatsu is a Seismologist.
Claudio Faccenna is a Geologist.
Thorsten W. Becker is a Geodynamicist.
This symposium intends to cover global and regional-scale deep Earth structural imaging, the links between deep structure and surface geology and related geodynamical modelling and analysis. Targets for imaging include the lithosphere-asthenosphere system beneath continents and oceanic basins, subduction and continental collision, the mantle transition zone, mantle plumes, the lower mantle/CMB and the core. Of particular interest are the large-scale mantle and lithospheric processes responsible for the Indo-Eurasia collision. Questions include: Why did the Indian plate move so fast, and what controlled its motion throughout the Cenozoic? What controls orogeny and deformation within the Indian and Eurasian lithosphere? How is the negative geoid anomaly over India related to deep mantle dynamics? How is regional plate tectonics affected by plumes and their potential surface impact, including the Deccan traps?

13.3 Imaging the Crust and Lithosphere Beneath the Continents
M. Ravi Kumar mravi@isr.res.in (India)

M. Ravi Kumar has made significant contributions towards investigating the shear structure, composition and deformation of the lithosphere and sub-lithospheric mantle and decipher their bearing on the evolution and seismogenesis in intra and inter plate tectonic environments.

High-resolution imaging of the crust-mantle structure holds the key to elucidate the evolution of the diverse geological provinces that constitute the Earth's surface. In spite of the rapid strides in imaging technology, the continental interiors, in particular small scale heterogeneities within continents, imprints of paleo-subduction, detection of weak discontinuities and their role in continental evolution largely remained tentative. Also, processes like horizontal accretion by shallow subduction or magmatic differentiation, mantle layering and dynamics, nature and depth to the Lithosphere- Asthenosphere boundary and Mid Lithospheric Discontinuity, their bearing on plate tectonics, strain localization and earthquake genesis, still remain to be resolved. Dense deployments of permanent and array type multi parametric geophysical instruments in a phased manner coupled with the development of powerful computers for processing and simulation has enabled high- resolution imaging of the spatial variations in the structure of various provinces. This symposium intends to address high-resolution imaging of the crust and mantle part of the lithosphere and its bearing on the evolution of the continents, geodynamics, plate tectonics and geohazards.

Keywords: mantle, core, continental collision, subduction, lithosphere-asthenosphere system

13.4 Crustal structure and Deformation in Active Tectonic regions with Special Reference to the Himalaya

Ajay Manglik completed his Ph.D. 1994; Scientist, CSIR-NGRI since 1989; Research experience in modelling of geodynamical heat and mass transport processes in earth’s interior, electromagnetic geophysics, and geophysical inversion. Group Head for airborne near-surface exploration and geophysical imaging of the NW Himalaya.

Lithospheric plate boundaries are the regions of active deformation and geogenic hazards, which are manifestations of the dynamic processes operative at multi-scales within the Earth’s interior. Understanding of these processes requires knowledge of the structure and physical/mechanical properties of the subsurface rocks besides information about the tectonic forces leading to deformation. Integration of resolvable images of the Earth’s interior obtained by various geophysical techniques coupled with geodetic measurements is needed for comprehensive understanding of active tectonic regions. .

The symposium aims to address topics related to geophysical imaging of the crustal structure of active tectonics regions and geodetic measurements. Special emphasis will be on the Himalayan collision belt and the Andaman-Sumatra subduction zone.

14.1 Regolith geology and concealed mineral deposits
Ignacio González-Álvarez Ignacio.Gonzalez-Alvarez@csiro.au (Australia)

Regolith units are the result of in situ and/or transported material, which has been affected by weathering processes. Understanding genetic aspects of regolith could help in mineral exploration by providing broader targets or obstruct exploration by concealing the bed rock targets, preventing easy sampling, concealing structures, lithological units etc. Genetic models of regolith mainly include climatic, geomorphological, pedological, tectonic domains and the classification of mapping units are mostly dependent on the terrain, scale and information extractability. In general, basic information like in-situ versus transported regolith, understanding provenance, effect of paleo to modern drainages are the key elements needed to the explorer. The various mapping techniques may include remote sensing, interpretation of geophysical data sets, geochemical sampling, spectrometric studies and ground validation etc. Several approaches are developed to map them. Currently, mineral exploration has concentrated on concealed deposits in regolith-covered terrains. Characterization of cover material as residual, transported or as complex nature by taking the aid from spectral studies, heavy minerals, geochemistry, age dating of detrital material etc. are the emerging techniques.
Genetic classification schemes for regolith, methodologies of mapping at regional and local scales, importance of a specific genetic class of regolith for a targeting particular mineral deposit, geochemical and geomorphological nature of regolith, methodologies of characterization of cover material, successful application of numerous techniques, effective use of varieties of geoscientific data sets and other related issues are the key subjects under this symposium.

14.2 Application of aerogeophysical Data Sets for Target Delineation through Basement Mapping/ Predictive Geological Mapping of Potentially Covered Terrains
B. K. Sahu sahubk2010@gmail.com (India)
A geological map of a largely covered terrain prepared using potential field data sets and outcropping geology is a predictive geological map. Regional potential field datasets are increasingly used to create the basement or predictive geological maps of regions with little or no outcropping areas. Evaluation of constrained density and magnetic susceptibility models with measured potential field data through modelling clubbed with known outcropping geological parameters plays a powerful tool to create the predictive geological maps of the covered terrains. The airborne magnetic data can through light on granitoid - gabbroid domains consisting of multiple generations of individual intrusions may give insights on the broad geodynamic models. .

Creation of the predictive geological maps involving identification of the near-surface and deeper responses and classifying the remaining responses according to their possible sources, integrated analysis of multiple data types, i.e. magnetics, gravity, radiometrics, conductivity, outcropping geology etc., to produce a more reliable model of the covered terrain or subsurface geology are the subjects under this category. The advancements and success stories related to delineation of mineral potential areas of covered regions, data acquisition, processing, spatial analysis, application of filters by airborne geophysical methodologies viz., magnetics, time domain magneto-gradiometry, gravity gradiometry, airborne electromagnetic etc., are the key discussion elements of the symposium..

 

14.3 Mineral System Approach for Enhancing Mineral Deposit Discovery Rate in the Potentially Covered Terrain
M. N Praveen praveenmn74@gmail.com (India)

Deeply weathered and regolith covered terrains may coincide with the tectonic domains and hence mineral system approach can help the explorer in targeting the mineralization below cover. Mineral exploration in covered terrain is challenging, requiring the development of new technical tools and approaches. Mineral system features include the geological setting, fluid drivers, fluid and metal sources, fluid pathways, depositional traps and post depositional modifications. All of these components link to geodynamic processes and the tectonic system. Transported cover is an obstacle to mineral exploration as it masks the detect Mineral System Approach for reversing the decline in mineral deposit discovery in the covered terrain table signature of buried mineral systems and dispersion of indicator elements to the surface. Mineral system gives an opportunity to generate prospectivity maps of potentially covered regions to enhance the rate of mineral deposit discovery. Translating mineral system elements into mappable criteria, delineation of presence of a particular mineral system in covered regions, new advancements in mineral system studies, various rankings for varieties mineral systems, identification of critical elements, working on greenfield regions for mineral potentiality etc., are the mine issues for this symposium.

14.4 Advances in Geophysical Approaches for Tracing Concealed and Deep Structures and Materials
M. K. Mukherjee  mrinal_km67@yahoo.co.in (India)

Geophysical techniques, such as seismic surveys, gravity modelling, magnetic data, deep electrical resistivity surveys, varieties of magneto-telluric methods etc., are all well-established tools for delineating shallow to deeper geological materials and structures of both covered and exposed terrains with variable degrees. The algorithms developed for handling observed gravity data by many geoscientists is growing to derive the structure of upper crust, sedimentary basin or both. Seismic reflection surveys generate the detailed images of the subsurface allowing to delineate structure and stratigraphy.

Highlights on delineation of fault systems and other crustal scale structures by using the data sets of seismic survey, gravity, magnetics, deep electrical soundings etc., and magneto-telluric models for deep conductive zones. Mapping of potential structural conduits, fault splay systems using remote sensing data, structural traps, structurally permeable zones of mineralizing fluids etc., shall fall in this symposium.

14.5 Ground Geophysical Methods of Gravity, Magnetic, Electrical, Electromagnetic to Bring Out Concealed Fertile Bodies
G. Karunakar karunakar65@yahoo.com (India)

Gravitational and geomagnetic measurements are useful to find underground targets that have significant differences in density and magnetism. Integration of petrophysical and geophysical data sets in the modelling process, such as gravity and magnetic field data, can provide crucial information as to the nature and distribution of density contrasts and magnetic material in the subsurface. In mineral exploration, for covered and partially covered regions, electrical and electromagnetic methods are used at regional to prospect scale for direct detection of electrically anomalous targets, in particular metal sulphide and metal oxide mineralization. Information about the geometry, dimensions and electrical characteristics of the sources of anomalies can be obtained. The magneto-metric methods are effective for sufficiently electrically conductive bodies may be related to the host rocks, to produce a measurable anomaly at deeper depths. Ground penetration radar surveys are for mostly shallow investigations of regolith hosted and placer mineralization in addition to determining the thickness and continuity of subsurface layers and cover materials.

Modelling source geometry, depth of source, responses from different litho-types, fault zones etc., of potentially covered regions by magnetic, gravity, electrical, electromagnetic are the main foci under this symposium.

14.6 Geochemical Techniques of Tracing Distal Footprints of Concealed Mineral Deposits
David Cohen d.cohen@unsw.edu.au (Australia)

As mineral deposit discovery rates decline, increased attention is being focused on geochemical exploration methods for application in covered terrains. Basement geochemical signatures are masked within the cover due to the geochemical and other intricacies of the regolith. Hence, majority of ore deposits those are hidden by burial and deep weathering are yet to be discovered. In a specific geo-environment when many geophysical techniques have limited application, geochemical methods can be used as an efficient tool for mineral exploration particularly, in regolith predominant terrains. Depletion and enrichment of specific elements and their selective ratios in primary haloes of certain mineral deposits have also been used for vectoring toward ore zones in recent times.

Pathfinder elements, various geochemical sample media, leaching techniques, threshold values, mobile metal ion methodology, vectoring towards ore zones, case studies on discovery of concealed deposits by geochemical techniques etc., are the elements considered in this symposium. Groundwater sampling techniques, analytical and interpretation techniques, trace metals and metalloid concentrations, isotopic applications, metal saturation, ion exchange, mobility in various environments, threshold values of indicator metals, buried mineral deposit discovery etc., and are also part of this symposium.

 

 

14.7 Recent Advances in Detection of Concealed Mineral Deposits by Integration Geoscience
M. N. Mishra mnmishra4@yahoo.co.in (India), R. Balaji (India)

Geological, geophysical, geochemical and geochronological constraints such as gravity & magnetic records, aerogeophysical data sets, magneto-telluric, seismic interpretations, geochemical data, drill hole information with an understanding on tectono-magmatic history and mineral system by integration geoscience approach significantly reduces the risk of mineral exploration, mostly for the largely covered areas. In a geospatial environment, various layers with different geo-scientific information may be overlain and analyzed as an integrated dataset for prioritization of detailed exploration. Construction of litho-structural maps using field observations integrated with airborne and ground geophysical data, satellite data, alteration maps, geochemical data sets etc., by various statistical modelling for various deposit styles, prospectivity analysis by index overlay, fuzzy logic etc., mostly to the cover dominant terrain are the main subjects encompass in this symposium.

14.8 Developments in Targeting Concealed and Deep Seated Uranium –REE Mineralization
A. K. Chaturvedi anandlko57@gmail.com (India)

With growing demand of sustainable clean Energy resources worldwide, nuclear energy has a very important role to play. Bulk of the world uranium resources are accounted for by the Proterozoic unconformity related deposits, Middle Proterozoic Iron Oxide Breccia complex and Phanerozoic sandstone type uranium deposits. Last decade witnessed significant advancement in understanding mineral deposits in relationship to internal and external processes of the Earth, exploration techniques, instrumentation, data processing and interpretation techniques. In particular, Airborne Electromagnetic methods (AEM) proved to be very successful in assisting uranium Exploration. AEM has proven to be particularly useful in places such as the central parts of Africa, South America and Australia, where approximately 80% of the landscape is covered by regolith and sedimentary basins. Integration of multi parametric geospatial datasets acquired over different geological terrains have been studied to delineate favorable locales for uranium exploration. These data sets include satellite imagery, aeromagnetic, aero-radiometric, airborne time domain electromagnetic, geological and structural data layers. Thematic layers of conductive horizons, faults and fracture zones, alteration zones, radio elemental rich zones, lithological, geochemical are extracted from geospatial data sets. GIS tools facilitate data transformation, visualization, analysis, modelling and spatial decision support required for integrating exploration datasets in generating mineral potential maps and in defining suitable zones for detailed uranium exploration. In addition to applying suitable geoscience applications of discovering Uranium mineralization as discussed above, the exploration of strategically important Rare Metals and Rare Earth Elements in beach sand placers, concealed alkaline suite of rocks and carbonatites in various geological environments are the main subjects under this symposium. Different Geophysical techniques, geochemistry etc., which are very successfully used in tracing such concealed deposits are also part of this symposium.

Dr. R. A Duraiswami and his students are actively engaged in the studying physical volcanology of the Deccan Traps, Sylhet Traps and the Javakheti Volcanic plateau, Georgia.

Stephen Self is the former Vice President (2011-2015) and Life Member of the International Association of Volcanology & Chemistry of the Earth's Interior (IAVCEI) and past leader of UK’s Volcanic and Magmatic Studies Group. He has worked extensively on volcanoes and continental flood basalt terrains of the world and is well published.

The Indian subcontinent hosts several Archean, Proterozoic and Mesozoic CFB provinces. The Archean volcanism and associated volcanic plumbing system of dyke swarms and sills in the Peninsular shields offer unique sites to unravel and understand petrogenesis of ancient flood basalt sequences. With over half a million square kilometres, the Deccan Traps is one of the better studied CFB provinces in the world. Attempts at integrating physical volcanology, geochemistry and geophysical studies to build 3-D facies architecture of volcanic successions and their impact on climate are ongoing. The Rajmahal Traps liked to the Kerguelen LIP, the Rajamundry Traps etc. are topics of interest. The symposium invites abstracts on current status of knowledge and future work possibilities by exchange of ideas and comparing provinces from India with other global CFBs like Karoo, CRB, Siberian Traps, etc.

Prof. Hiro Yamagishi is a noted volcanologist from the Geological Survey of Japan who has worked extensively on Island arc volcanism. He has publications on geochemistry of island arc basalts and volcanology of pillow lava-hyaloclastite sequences from the Japanese and related arcs.

 Dr. Tapan Pal has dedicated his service at Geological Survey of India on studying the Andaman and Nicobar volcanism. His notable works include the study of pyroclastics from the Barren Island volcano.

Island arc volcanism is closely associated with the subduction of ocean and continental lithosphere and produce spectacular archipelagos of stratovolcanoes that constitute the famed ‘rings of fire’. These include many famous volcanoes like Etna, Vesuvius, Pinatubo, Fujiyama, Krakatau and Toba to name a few. These stratovolcanoes are notorious for violent explosions and stratospheric mass loading that lead to greenhouse effects and climate change.
India-Asia collision produced island arc in the NW Himalayas and along the Andaman and Nicobar Islands. These regions are closely associated with Island arc volcanics (Khardung, Dras, etc) or with dormant and active volcanoes like the Narcondam and Barren volcano. Besides these, the Taftan-Bazman (Iran) and Kuhi-e-Sultan (Pakistan) are important stratovolcanoes in the vicinity of the subcontinent. The symposium aims to review the latest status of research in Island arc volcanism and will focus on the siesmo tectonics, volcanic products, monitoring and mitigating natural hazards posed by this type of volcanism.

Dr. Karol Nemeth’s areas of expertise include physical volcanology, magma-water interaction research, and volcanic hazard studies. Nemeth’s research is centered on understanding monogenetic volcanism and volcanic field evolution across the globe.

Dr. Makarand Bodas was a member of the team that established stratigraphy of a thick lava pile of the Western Deccan sequence using geochemical signatures. His current interests are i) understanding relationships between lava morphologies and different types of slope failures in the Deccan Province and ii) studying transitional flows in the Deccan Province.

Dr. Loyc Vanderkluysen research involves wide array of methods, ranging from volcano monitoring and thermal remote sensing, to high-temperature geochemistry, igneous petrology, and experimental volcanology.

Under this symposium, we invite multidisciplinary contributions addressing various aspects of study of volcanic rocks from the older sequences to active and contemporary volcanic fields. The use of Deccan basalts and trachyte in the range of Indian architectonic heritage, from antiquity to current times, is quite fascinating. The world famous Ajanta and Ellora caves, forts, temples and ancient, medieval and contemporary buildings in and around Pune-Mumbai are perfect examples of how the basalts have carved a niche in the cultural ethos of the people for western India. The symposium invites contributions highlighting various methods of study of volcanic rocks on earth and other planets, their importance in human civilization.

17.1 Geochemical and Chronological Perspective of Stars to Planets
G. Srinivasan gopalan.srinivasan@gmail.com (India)

Dr. G. Srinivasan is geochemist/ cosmochemist and has worked extensively on accretion and evolution of planetesimals, production of short-lived radionuclides and differentiation of asteroids. His work on primitive meteorites led to the discovery of 41Ca in early solar system and his work on differentiated meteorites established the role of 26Al as a heat source for planetary melting.

The astrophysical evolution of the Universe is mirrored in the bulk elemental abundances in the Solar System. More than 99% of the Solar System is composed of remnants from the Big Bang - hydrogen (H) and helium (He) and trace amounts of Li, Be, and B. The remainder of the elements in the material inventory is the product of nucleosynthesis from variety of stellar sources, e.g., supernovae, late-stage stars, and novae. The nearly uniform elemental and isotopic composition of planetary bodies suggests that nebular parent material was well mixed. However, vestiges of various stellar sources are manifest in the isotopic composition of presolar grains, Ca-Al-rich inclusions in primitive meteorites and heterogeneities in bulk meteorites. These heterogeneities pose a challenge for interpretation and modelling the geochemical evolution of terrestrial planets. At the same time the variable isotopic composition provide insight into the astrophysical setting in which our solar system formed and the processes that prevailed. The gas-solid chemical fractionation of elements in the nebula drove the compositional variation in primitive meteorites. The accretion and growth of planets and large asteroids was followed by their large scale melting resulting in metal-silicate fractionation, a process that resulted in core-mantle formation. The differentiation of mantle and the formation of crust led to further fractionation of elements based on their compatibility. The Earth as a planet or our solar system as a whole cannot be viewed in isolation but have to be understood in the context of other planetary systems around distant stars. This symposium invites abstracts covering all these aspects.

17.2 Geochemistry of Earth’s Crust and Crustal Evolution
Allen Nutman anutman@uow.edu.au (Australia)

Professor Nutman extensively worked on Archaean and Palaeoproterozoic crustal evolution via high-grade gneiss complexes mostly in Greenland and Australia, but also in China, Brazil, Russia and India. He has vast experience on SHRIMP ion microprobe U-Pb geochronology.

The 1970s marked a revolution in the Earth sciences with the growing availability of accurate and precise absolute geochronology and the acceptance of the plate tectonic mechanism to explain major features of the lithosphere. Over the last fifty years, there has been continuous debate regarding the extent to which the modern tectonic processes are compatible with the ancient geological record. This is particularly so for the Archaean and Proterozoic, which encompass 3.5 billion yeas (~75%) of Earth’s history – with continuing debates centered around first-order questions: (i) What was the volume of continental crust through time and how did it form; (ii) when did ‘modern’ plate tectonics start and (iii) the significance of hydrosphere – atmosphere interactions on the lithosphere and the emergence and spread of life. This multidisciplinary symposium draws together contributions from the diverse realms of trace element and isotope geochemistry and geochronology, integrated with tectonics, metamorphic and sedimentary geology. The key aim of this symposium is to explore how deep in Earth’s time does James Hutton’s ‘The present is the key to the past’ hold true.

Keywords: Crust, evolution, composition

17.3 Evolution of Earth’s Atmosphere and Ocean: Geological and Geochemical Perspective
Andrey Bekker andrey.bekker@ucr.edu (USA)

Prof. Bekker is widely known for his contributions to our understanding of atmospheric oxygen evolution during the Precambrian. He has provided the first timing constraints of Great Oxidation Event. He has worked on Lomagundi excursion events, S, O, Fe, Ti and U isotope systematics in understanding the redox evolution.

Earth underwent the most dramatic environmental changes in the early Paleoproterozoic and late Neoproterozoic when supercontinents assembled and broke-up, multiple Large Igneous Provinces were emplaced, major perturbations in the biogeochemical carbon cycle took place, atmosphere and oceans were oxygenated, multiple global glaciations occurred, and major innovations in the evolution of life happened. Bracketed by these two time periods of environmental turmoil, the ‘Boring Billion’ has also been in focus of the recent research with the emphasis on whether low oxygenation of the oceans or shallow-marine settings played a key role in the delayed evolution of life. Leading to the Great Oxidation Event in the early Paleoproterozoic, localized oxygenated settings or short-lived, transient oxygenation events has been inferred in the otherwise anoxic surface environments. There has been significant progress in our understanding of these events, yet cause and effect relationships among them are poorly constrained and remain highly speculative. Early Earth’s plate tectonics and geodynamics are also poorly understood, yet they provide a backdrop for all these evolutionary changes. New state-of-the-art geochemical and geological proxies has been developed and applied to constrain these events and their relationships. High-precision geochronology provides precise ages to calibrate these events and correlate globally. Geochemical modelling matured to address uncertainties in our understanding of the biogeochemical carbon cycle, nutrient cycling, and chemistry and redox state of the atmosphere and oceans in the Precambrian. Early Earth’s history also provides now an insight into exploration for life on other planets. Contributions dealing with any of these aspects will be welcome to this symposia.

17.6 Environmental Forensics of the Transport and Fate of Contaminant in Soil and Freshwater Systems
Prosun Bhattacharya prosun@kth.se (Sweden), Manish Kumar (India)

Over the past decades, environmental forensic/ archaeological geochemistry has come up as one of the most vital zone of environmental studies. This symposium will provide a prestigious platform for the young dynamic scientific investigators, who are involved in addressing various issues of environmental contamination owing to its source and in relation to historical reconstruction of the release of these contaminants into the environment. Although the data furnished by traditional EPA approach can be very much useful and handy for monitoring purpose, but its importance is diminished when investigators aims at determining the source of contaminants/ point of release and migration pathways.

The present symposium intends to address the unanswered question relating to identifying the sources/ point of release of contaminants, by integrating a variety of analytical techniques or tools, analysis of the acquired data into a unified comprehensive data set. The symposium will give emphasis on: Contaminant Fingerprinting for source identification and/or age-dating, including chemical, isotopic, chiral, mineralogical /microscopy techniques, DNA and tree-ring fingerprinting. Specific Evaluative Techniques for source identification and/or age-dating including historical document and aerial photography review, signature chemicals, atmospheric tracers and markets forensics, background concentration evaluations

Global-scale, or continental-scale, geochemical surveys cover millions of square kilometers of the Earth’s surface generally at a very low sample density (1 site per 1,000 to 10,000 km2). Geochemical patterns produced from these low-density surveys are connected to processes related to many factors including tectonics and climate and in turn to weathering, geochemical and mineralogical composition of the original soil parent material, continental-scale glaciation, topography, regional-scale alteration and mineralization, and in some cases, human activity. Over the past 15 years, several global-scale geochemical surveys have been conducted (Australia, China, Europe, India, Mexico, United States) and the data and maps are being used as a tool to aid in environmental and resource management. This symposium aims to focus on case histories from global-scale geochemical mapping programs, the lessons learned from the surveys, and the opportunities for utilizing the data for the benefit of humankind. In addition, presentations of results from higher-density geochemical surveys conducted at national to local scales.

18.6 Quantitative Mineralogy – Applications and Value in Geoscience Systems
Shaun Graham shaun.graham@zeiss.com (UK), Vishwanath Uppugunduri (India)

Shaun Graham is a leading specialist in automated and quantitative mineral analysis. His particular research focus is the development and application of quantitative mineralogy techniques into a wide variety of materials and geoscience applications. His key focus areas currently are understanding how the multi-scale data acquired from these technologies can be used to deepen our understandings of complex systems (i.e. mineralogy processing circuits, ore genesis and mineral exploration targeting). Throughout the last 5 years he has contributed over 30 abstracts to international conferences, contributed to multiple peer-reviewed publications and supervised a number of Masters and PhD students.

Vishwanath Uppugunduri is one of the leading Geomettlurgists in the country with experience of more than 35 years in the base metals, precious metals and ferrous metals fields in India and abroad having served as Head Of R&D of HZL (Vedanta), where he initiated a number of recovery improvement projects based on the inputs of quant minerology which has helped HZL to become a world leader with highest recoveries of Lead, Zinc, Silver.

At the very essence of any applied physical science is the generation of quantitative data that is used to characterize, understand and explain complex systems. The techniques used in this application therefore provide extensive value in quantification of mineralogy, textures and complex associations across a range of scales. These quantitative studies therefore enable us to understand the system is greater detail and scale our quantified observations from the nanometer all the way through to the kilometer scale.

This aim of this symposium is to provide a forum for researchers to share ideas, new techniques and technologies and applications of automated and quantitative mineralogy. Whilst these capabilities have in the past primarily been a technology utilized in the mining community for Geometallurgy and process mineralogy (which is still a core theme of the symposium). However, papers demonstrating other applications in petrological studies (igneous and metamorphic), sedimentology, oil and gas / digital rock physics, etc. are encouraged.

Prof Akira Imai is Professor of Economic Geology, Kyushu University, Japan and Vice President of the Society of Resource Geology. He has been extensively working on the genesis of base and rare metal resources, porphyry Cu and epithermal Au deposits in island arc settings of western Pacific rim and SE Asia.

Prof Hai Than Tranh is Professor of Geology and Tectonics, Hanoi University of Mining and Geology, Vietnam. He has been a leader on structural, geotectonic and metallogenic evolution of Vietnam and development of suture zones and amalgamation of crustal blocks in SE Asia.

South East Asia Region is vastly rich in base metals, precious metals, tin–tungsten, gems and hydrocarbons and provides great exploration challenges to develop these resources in a sustainable manner. The region consists of a collage of continental blocks or fragments such as South China, Indochina, Sibumasu, and West Myanmar-Sumatra terranes which were rifted away from the margin of Gondwana at different periods in the Phanerozoic, and led to the opening of the Palaeo-, Meso- and Neotethyan (or Cenotethys) Oceans. Throughout the long history of Gondwana supercontinent break-up and subsequent accretion of these crustal terranes and amalgamation, various rifting, subduction, opening and closure of back arc basins, ophiolitic obduction and arc-continent/continent-continent collisions have occurred, and formation of mineral and hydrocarbon systems were related to these tectonic processes. Recently, advances have been made in understanding the results of these tectonic processes, through the study of geochronology, geochemistry, seismicity, stratigraphy and structure. In this symposium, we welcome contributions of current development of metallogenic, regional geological and tectonic evolution.

Dr Roger Skirrow has studied IOCG deposits along with many other mineral deposit types for more than 30 years, mainly in Australia while working as a research scientist at Geoscience Australia. His interests include hydrothermal geochemistry, applications of geochronology and isotope tracing in hydrothermal systems, tectonic and geodynamic settings of IOCG and other mineral systems, and mapping of mineral potential. DrSkirrow was an Associate Editor of Economic Geology for 5 years, and is now the SGA Regional Vice President for Oceania.

Prof. Huayong Chen graduated from Queen's University, Canada and worked as a Research Fellow at CODES, University of Tasmania, Australia. He has been a professor on Economic Geology in the Guangzhou Institute of Geochemistry, Chinese Academy of Sciences since 2012. His work covers a range of hydrothermal deposits, especially on IOCG and porphyry-epithermal systems. He will hold the position of Chief Editor of Ore Geology Reviews from 2019, and has been an Editorial Member of Mineralium Deposita since 2016.

IOCG deposits are epigenetic, hydrothermal, resources of Cu and Au (± U, REE, Ag, Mo, Co, Bi, etc), spatially associated with abundant (>10 %) low-Ti magnetite and/or hematite, and exhibit characteristic potassic, sodic and hydrous alteration mineral assemblages. IOCG deposits, exemplified by the ~10 billion tonne Olympic Dam Cu-U-Au deposit in South Australia and several giant deposits in the Archean Carajás district in Brazil, are distinct from typical porphyry, skarn and iron oxide-apatite deposits. However, the definition and classification of IOCG deposits has been a topic of enduring controversy since the initial recognition as a separate deposit type in the 1990s.There are also many questions remaining to be answered on the nature and origins of the hydrothermal fluids, sources of metals, and tectonic and geodynamic settings of IOCG deposits. All these will be the main issues to be discussed in this symposium.

Dr. Mohamed Shareef: Integrated studies involving granitoid evolution and associated Cu-Au mineralization in Dharwar Craton. Since last 11 years actively involved in granite metallogeny from Dharwar and Bastar craton with focus on Cu-Pb-Au-Mo and REE mineralization.

Granite magmatism and related mineral deposits are linked to diverse and complex geological processes. These metals and non-metals are not only indispensable for strategic and high-end technological applications (U, Th, Sn, W, Mo, Nb, Ta, Sb, F, Cu, Pb, Au), but also many of the elements (Be, Li, Ga, Zr, Hf, Y, REE) upon which current societies are increasingly becoming dependent. With the advent of advanced analytical techniques, a coherent genetic model can be worked out. Elucidation of such models provide insights in unravelling specific granite magmatism, viz., S-, I-, A-, M-, P-types, which occur in specific tectonic settings. This symposium will provide an opportunity to revisit the known styles of mineralization in granites and advances in related mineral exploration techniques.

Prof. Craig Storey is Professor of Geology and Associate Head (Research) at the University of Portsmouth, UK. Prof Storey is geochemist and petrologist with a particular interest in understanding the role of and developing the use of accessory minerals to monitor magmatic, metamorphic and metallogenic processes; specializes in in-situ measurement of trace elements and radiogenic isotopes supported by advanced electron imaging and crystallographic characterization. Prof Storey is an Associate Editor of Mineralogical Magazine and has previously been Vice President of the Mineralogical Society of Great Britain and Ireland.

The spectrum of metal deposit types generated in arc systems is a broad one, but each deposit type can be related to one of the specific tectonic sub-domains within subduction-related volcano plutonic settings. The most fundamental process operative at convergent plate margins is the subduction of oceanic lithosphere, and therefore, it is reasonable to seek an explanation for variations in arc metallogeny in terms of variations of the subducted materials, the style of subduction, and the stress regime in the overriding plate. Metal deposits formed in the principle arc systems as well as inner side of the arcs and arc-related rift include: Porphyry – type deposits, Copper – bearing breccias pipes, Skarn deposits, Epithermal (vein-type) deposits, Massive Magnetite deposits, Manto-type Copper deposits, Contact metasomatic deposits, Polymetallic vein deposits, Back arc gold deposits, Climax – type porphyry molybdenum deposits, Kuroko – type massive sulfide deposits, Palaeozoic volcanic – hosted massive sulfide deposits, Base metal vein deposits, Metal deposits related to fore arc felsic magmatism, Massive sulfide deposits in greenstone belts, Vein – type gold deposits in greenstone belts, IOCG, and Mississippi valley type deposits.

Dr. K.R. Hari has research interest on lithospheric architecture and geodynamic setting of mantle and also understanding the metallogeny of precious metals (diamond, gold and PGE) mineralisation, integrating petro-chemistry, mineral chemistry of ores, rocks, fluid inclusion studies, stable isotope systematics and modelling. He has more than 25 years of teaching and research experience.

Dr. E. Sajhi is having more than 18 year teaching and research experience and is an associated editor of Geoscience Frontiers (An Elsevier Journal). He has published several research articles in reputed international journals.

Plume generation, migration and impingement in the lithosphere have considerable role in the formation and disruption of supercontinents and generation of mineralized systems. The tectonic cycles have a direct relationship to metallogeny because of the interaction between the continents, tectono-thermal processes related to the orogenic and anorogenic systems, biotic evolution and global sea level changes. The direct and indirect relationship between magmatic and hydrothermal ore systems and their association with mantle plumes can be proxied by the emplacement of mafic and ultramafic magmas associated with flood basalts and LIPs (Large Igneous Provinces), layered intrusions, giant radiating dyke swarms and rift systems. This symposium intends to address connections between mantle plumes, plate motions, continental assembly and breakup, dyke swarms, intraplate anorogenic volcanism and associated ore deposits.

19.6 Manganese metallogenesis in terrestrial rock record
Dillip Ranjan Kanungo dilliprkanungo@gmail.com (India)

Dr. Dillip Ranjan Kanungo has research experience on mineralogy and geochemistry of manganese ores and associated rocks related to metallogeny, with expertise in EPMA, SEM, XRD & DTA techniques. Possesses 21 years R&D experience in mineral characterization and beneficiation studies of different ores of Indian and foreign origin. Recipient of the IIME Mineral Characterization (Peravadhanulu) Award.

Manganese occurs in a large span of terrestrial geological record within diverse depositional environments. The four dominant modes of Mn-depositing processes are euxinic basin sedimentary, oxygen-minimum zone sedimentary, volcanic, and karstic processes. Superimposed on these are supergene and metamorphosed Mn ores. In Earth history, the reasons for time gaps in Mn deposition from 2700 to 2300 Ma in the Early Archean and a well-defined gap in sedimentary rock-hosted deposits between 1800 and 1120 Ma, excluding some large volcanic rock-hosted accumulations, requires global attention. The cause of virtual nonexistent of Mesoproterozoic sedimentary rock-hosted Mn deposits is debatable, as there is a major sedimentary rock-hosted deposit of Wafangzi in northeastern China between 1800 and 900 Ma and the age of Sausar manganese belt, central India is controversial. Mn(III) phases are considered as short-lived redox player in suboxic environments, but widespread observations of stable and abundant Mn (III) phases in the rock record needs more discussion. Post-depositional processes and their impact on manganese mineralogy and redox state require detail deliberations. Significance of local basin tectonics rather than global parameters and partitioning of Mn from Fe irrespective of potential source rocks and their control on Mn mineralization from Archean to Recent in terrestrial rock record are some of the points, besides those mentioned above, to be examined and discussed in this symposium.

19.7 Rift Related Mineralization: Geological and Geophysical Perspectives
Prabodha Ranjan Sahoo prabodha@iitism.ac.in (India), G Sreenivas Rao (India), Sahendra Singh (India)

Dr. Prabodha Ranjan Sahoo: His research interest is in understanding the metallogeny of precious (gold and PGE) and base metals using fluid inclusion studies, stable isotope systematics and modelling concept-based exploration strategies. Recipient of the National Geoscience Award, Government of India, for significant contribution in mineral discovery and exploration.

Dr. G Srinivasa Rao: His research interest is in understanding the lithosphere architecture and geodynamic setting of continental lithosphere and its implications on metallogeny, based on integrated geophysical techniques. He is the recipient of the Inspire faculty award, DST, Government of India and best thesis award from IIT Bombay and Association of Exploration Geophysicists (AEG), India.

Dr. Sahendra Singh: His research is focussed on the metallogeny of orogenic gold and refractory gold within wide varieties of litho types e.g. greenstones, carbonates and QPC. He has more than 20 years of teaching and research experience, has published several research articles in reputed journals.

Geodynamic processes have significant bearing on metallogenesis. A wide variety of mineral deposits e.g. Cu, Pb, Zn, Mo, Ni, PGE and REE’s are formed due to rifting of oceanic and continental crust and occur in association with diverse litho types in global scale. The Intra-cratonic basins, believed to have developed in a rift setting, are potential sites of giant ore systems, such as sedimentary exhalative (SEDEX), stratiform, stratabound and Iron oxide copper gold (IOCG) deposits. However, their mechanism of formation is not yet fully understood. Many of the features previously ascribed to subduction-related systems have been explained by post-collisional intracontinental and extensional settings. The influence of mantle-related magmatic processes such as emplacement of orogenic rift related granites, alkaline rock-carbonatite complexes and kimberlites are also less understood and need attention. This symposium calls abstracts on all these issues.

20.1 Biodiversity
Vipul Sharma vipul.sharma@iucn.org (India)
Vipul Sharrma is an accomplished environment and development professional with eight years of extensive experience on Business and Biodiversity.
Biodiversity considerations are relevant throughout the mining life cycle – from discovery or reconnaissance, to exploration or prospecting, development and production, and finally to decommissioning and closure. Although mining companies are generally aware of the mandate, there are cases of failure to fully consider the interdependencies between mining, biodiversity and society in the assessment of impact, which translate into implications for human well-being (livelihoods, safety, security and health). The identification of these impacts at an early stage can streamline decisions about where, or where not, to develop mines, as well as about how to develop them.
This symposium aims at discussing good business practice to incorporate appropriate scientific methodologies that encompass all levels of assessment of impact on biodiversity and ecosystem services, stakeholder engagement, and comprehensive economic valuation of the affected areas into business decision-making.

20.2 Reporting Sustainability
Biswajit Paul biswajit@iitism.ac.in (India)

Dr Paul is Associate Professor,Centre of Mine Environment,Department of Environmental Science and Engineering.He ha rich experience in field,academics and consultancy.

Sustainability reporting is not just report generation from collected data; instead it is a method to internalize and improve an organization’s commitment to sustainable development in a way that can be demonstrated to both internal and external stakeholders. Sustainability reporting can help organizations to measure, understand and communicate their economic, environmental, social and governance performance, and then set goals, and manage change more effectively. Analysts often consider a company’s sustainability disclosures in their assessment of management quality and efficiency, and reporting may provide firms better access to capital. This symposium intends to discuss reporting methodology as a unified standard that may allow reports to be quickly assessed, fairly judged and simply compared.

20.3 Policy Initiative and Framework
Ashish Dash ashis001@gmail.com (India)

Ashish Dash is working on policy advocacy and sustainability and he is actively enaged in various committees constituted by Ministry of Mines.

The extraction of mineral reserves has always resulted in varying degrees of environmental resource degradation and social impacts, including displacement, all across the globe. The mining industry across the Globe has been facing criticism on several issues relating to its performance vis-à-vis sustainable development.The Mineral Policy needs to hold a comprehensive view to facilitate the choice or order of land use keeping in view the needs of development as well as needs of protecting the Forests, Environment and Ecology. The concept of SDF can be traced back to 2001 when the world’s leading multinational mining companies decided to go for an image makeover by promoting the organization - International Council on Mining and Metals which developed a social and environmental wish-list, the SDF, which its members were to comply with voluntarily. The SDF framework outlines a working definition for sustainable development in the mining sector as - "Mining that is financially viable; socially responsible; environmentally, technically and scientifically sound; with a long term view of development; uses mineral resources optimally; and, ensures sustainable post-closure land uses” This symposium intends to revisit SDF for its implementation

G K Pradhan gkpradhan58@gmail.com (India)

Prof Pradhan is Dean and Faculty of Engineering and Technology at AKS university.He is also editorial member of the IME Journal.He is recipient of National Geoscience Award for 2012 under Mining Technology category.

In many developing countries, the public sector continues to play a dominant role in production of various minerals (coal, lignite, petroleum, iron and steel, bauxite and aluminium). A simple and transparent mechanism for granting mining lease or prospecting licence through competitive bidding is in place besides assured tenure and easy transferability of mineral concession granted through auction, strict penalty provision to deter illegal mining.
Mine reclamation, use of non renewables, community engagement, water management are among the area where few mining companies are leading with innovative approaches.
With journey progressing steadily, this symposium invites abstracts on sustainability practices in mining industry that will be able to change the perception of regulators, community, civil society and other stakeholders.

21.1 Altering Biogeochemical Cycles in Changing Climate

Rajesh Agnihotri is expert of stable isotope geochemistry with strong research interests in short term to long term changes in the climate system and associated biogeochemical changes.

Prof. Mark A. Altabet is an expert in stable isotope biogeochemistry with particular research interests in ocean nitrogen cycling present and past and its alteration by human impacts and climate change.

Dr. V.V.S.S. Sarma is an expert in trace gases emission and food web dynamics using stable isotopes of carbon and nitrogen and estuarine biogeochemistry

Global climate change (anthropogenic warming) may induce glacial retreats in high-altitude environments and expose new landscapes that were usually under snow-cover and remained barren for several thousands of years. Enhancing vegetation/ greenery in the form of mosses, lichens, grasslands could be seen over the peripheral regions of polar icecaps, high-altitude environments of western Himalaya and Peruvian Andes. This effect could significantly alter Carbon and Nitrogen biogeochemical cycles and impact regional ecology. Likewise, enhanced (N based) fertilizer usage in agricultural lands worldwide, modified soil erosion, and other anthropogenic processes could significantly change C and N inventories to the coastal oceans. Demand for bio-utilizable N is increasing at the rate of ~2% annum globally to meet out world agriculture demand. This may significantly change greenhouse gas budgets on global scale. In addition, inter-linking rivers and construction of more dams are expected to modify estuarine and coastal biogeochemistry. For instance, deglaciated terrains may increase cyanobacterial diversity and activity with enhanced photosynthetic rates. In addition, enhancing air pollution in densely populated cites can increase anthropogenic aerosols loading and coastal ocean biogeochemistry with reference to primary production and acidification. Taken together, multi-disciplinary approaches including stable isotopes of C and N are needed to characterize aforesaid effects and glean this in sedimentary records. These anthropogenically modified geological imprints from natural repositories are needed to understand and quantify rates of changing ecosystems in an anthropogenic induced climate era. This symposium invites contributions on various aspects of climate change effect on biogeochemical cycles.

The climate change is one of the most important topics of the ‘Assessment Reports’ of the Intergovernmental Panel on Climate Change (IPCC). The major concern is the increasing atmospheric CO2 levels causing environmental warming and associated sea level rise during the 21st Century. There is no doubt that some such changes are now adequately known having small uncertainties, however, there are a number of areas where our understanding is poor such as pattern and flux of future precipitation, El Nino and Southern Oscillation (ENSO) as components of climate system, changes in ice-sheets and sea level, and so on. The poor knowledge over these aspects limits our ability to plan adaption and mitigation strategies to meet the challenges of future climate change. An important aspect towards this is the lack of observations of relevant changes and associated processes as our instrumental record is very short. However, the limitation of short climatic instrumental records may be overcome by palaeoclimate studies employing range of tools that have the capability of meeting uncertainty of future predictions. Physical, chemical, and biological proxies respond to environmental conditions that help in palaeoclimate reconstruction for periods before instrumental records. These proxies such as sediments, ice cores, tree ring, etc. can provide information on climate variability that cannot be provided by direct observation of the modern climate. Some of the important key research approaches are i. Proxies used for palaeoclimate reconstruction need to be better calibrated emphasizing the uncertainty in their use and involve the forward modeling of proxies in climate models; ii. Comparing the Model-data with palaeoclimate data retrieved using different tools; and iii. Testing models against the wide range of climate behavior observed in the past. All these will help us to minimize the uncertainties and make the future climate predictions more reliable. Contributions on these topics are invited under this symposium.

21.3 Asian Monsoons and their Drivers from Mid-Holocene through Current Period
Karumuri Ashok ashokkarumuri@uohyd.ac.in (India), Mat Collins (UK)

Prof. Ashok is an expert tropical Indo-pacific variability and teleconnections, earthsystem modelling, and seamless prediction. His other interests include weather & climate prediction applications, past and future climate simulations, and understanding long term changes in the links of Indian summer monsoons with its driver.

Prof. Mat Collins is a renowned expert on ENSO variability, and  Dynamics of the Indian Monsoon. His interests include climate modelling, climate variability and change, and quantifying uncertainty in climate projections.

The Asian monsoons sustain life and economy of many nations. Studies based on observations show that the monsoons vary through diurnal and multi-centennial time scales. The ENSO, Indian Ocean Dipole, Eurasian snow cover, Mascarene High, etc. are some of the documented drivers of the monsoon variability. Interestingly, recent studies suggest a changing driver such as the ENSO. While the role of anthropogenic climate change has been suggested to be a factor for these recent changes as well as global warming in the last 3-4 decades, notably, changes such as continental scale warming have been also documented during the medieval warm period, through proxy-data analysis (IPCC, 2013).

In this symposium, simulation studies addressing the Asian monsoons variability and their teleconnections to various drivers from Mid-Holocene through the current period are invited. The ENSO variability is suggested to be relatively weak during mid-Holocene period, and the last millennium period is analogous to the historical climate period in terms of external forcing. Therefore, studies on these two periods and those which compare such simulations with proxy data and with present day climate simulations are welcome. Studies which explore other important aspects relevant to monsoons or their drivers will also be considered.

21.4 Air Quality, Environment and Public Health Impacts in Asia

Prabir Patra is an expert of greenhouse gases modelling with strong research interests in short-lived air pollutants and their controls through hydroxyl (OH) radical chemistry. He

A. P. Dimri is climate model experts and work on science of climate change.

As per the World Health Organisation (WHO), an estimated 4.2 million premature deaths globally are linked to ambient air pollution. Ambient air pollutants for public health concern are particulate matter of less than 2.5 microns in diameter (PM2.5), ozone (O3), nitrogen oxides (NOX) and sulphur oxides (SOX). The air pollutants promote heart disease, stroke, chronic obstructive pulmonary disease, lung cancer, acute respiratory infections in children, and may harm cognitive intelligence.
Studies suggest about two-thirds of all air pollution related deaths occur in Asia, which is home to all of the top 20 World’s most polluted cities. Fourteen among 20 of them are located in India (www.bbc.com; 2 May 2018). The sources of air pollution are linked to infrastructure developments, power generation technologies, agricultural waste management and cooking with polluting fuels in the developing countries.
The atmosphere near the Earth’s surface plays a major role in processing the gas phase species (NOx, SOx, volatile organic compounds) into the particulate phase (e.g., PM2.5), which affects human health and visibility that bear huge economic implications for both land and air transport sectors. Amount of air pollutants in the cities can be transported hundreds of kilometers to the rural areas and vice versa depending on the winds direction and speed, and stability of the atmosphere (boundary layer meteorology).
The interactions between the sources of air pollutants, air chemistry and atmospheric transport will be addressed in this symposium. Based on the Asia specific deliberations in the presence of international experts, we hope to come up with South Asia-specific solution to mitigate air pollution.

21.5 Aerosol-Cloud-Radiation-Land Surface Interactions and Feedbacks: Consequences to Water Cycle During India Summer Monsoon
Sachchida (Sachi) N Tripathi snt@iitk.ac.in (India), Ilan Koren (Israel)

Dr. Tripathi is an expert on aerosol direct and indirect effects, and has been working in this field for more than two decades now. He has investigated in depth, several aspects of aerosol-cloud-radiation-surface interactions during Indian monsoons, especially for the Indo-Gangetic Plains. Other than these, his research interests also include aerosol effects in regional climate-chemistry models, as well as developing new techniques for aerosol absorption.

Dr. Koren explores clouds and rain and their links to processes in the oceans. Focuses his research on problems related to aerosol-cloud interactions, complex systems, self- organization, and emergent behavior in cloud fields. In parallel he explores links and feedbacks between marine ecology, air-sea exchange and clouds.

Aerosol, is a key component of the lithosphere-hydrosphere system, and thus implicates sustenance of life. Ambient aerosols modulate atmospheric stability, land-sea thermal contrast, water availability etc. through effects on radiation, snow albedo, cloud properties, etc. These processes in turn feedback aerosol distribution. Nonetheless, surface properties and environmental variability also affect the aerosol-processes and feedbacks. The goal of this symposium is to explore interactions among aerosols, cloud, land, radiation and human activities from regional to global scales. We invite abstracts of observational and modeling studies exploring: (1) aerosol-radiation interaction, the role of aerosols in exchanging heat and water masses at the earth surface including energy flux partitioning, snow-ice darkening effects, impacts on lower troposphere, and associated feedbacks, (2) aerosol-cloud interaction and their impacts on monsoon hydrological cycle, (3) impact of atmospheric circulation and monsoon convection on the aerosol emission, transport, deposition, and atmospheric haze over the earth’s major continents . Other topics related to aerosol impacts on the regional climate system and weather are also welcome.

21.6 Monsoon Dynamics

Dr. Roxy Mathew Koll is leading research on climate change and its impact on the monsoon, the rapid warming in Indian Ocean and the marine ecosystem. He is a Co-Chair of the CLIVAR Indian Ocean Region Panel, and a Lead Author of the IPCC Special Report on Oceans and Cryosphere in a Changing Climate. He was named the Kavli Fellow by the U.S. National Academy of Sciences and the Indian Meteorological Society felicitated him with the Young Scientist Award in 2016.

Prof. Deepti Singh is a renowned expert on monsoon variability and climate extremes. Her research explores the physical drivers of climate extremes, and their impacts on agriculture, water availability and human health, particularly in monsoonal climates. She was named the Kavli Fellow by the U.S. National Academy of Sciences.

The monsoon dominates the socio-economic livelihood over Asia, including the water resources, agriculture and power generation. Therefore, the changes and extreme events associated with the global warming is of utmost importance to the lives of over two billion people over the monsoon region. Through observations and modelling, the scientific community has advanced its understanding of the past and future changes of the monsoons. In the global warming scenario, it is found that the rainfall pattern has undergone substantial changes with tendency for more extremes. Most of the studies stick to the “wet getting wetter and the dry getting drier”, though a few research suggest decrease in rainfall over some of the monsoon regions. The IPCC AR5 is also suggestive of the uncertainties looming over the status and fate of the monsoons.

Monsoonal changes are found to be different when the region and time-periods considered are different – and so are the implications. Thus, there is an urgent need to provide more regional-scale information through the use of weather and climate models that could resolve small-scale features. Spatial and temporal changes in temperature, wind and rainfall are vital. This will hopefully provide more information on how climate change will affect the rainfall (monsoon and otherwise), wind and other extreme events, such as warm/cold episodes. In particular, the future decision strategies in the renewal energy world must be designed to consider the uncertainties and probabilities of weather and climate. This symposium is setup to bring forth the uncertainties and new understandings regarding large scale and regional changes over the monsoon regions. All climate change studies, past and future, related to the monsoon and associated extreme events, are invited.

Prof. Bookhagen is an expert on mountain geomorphology and the impact of climate changes on transport processes in mountains. He is an active researcher in the Himalaya with two decades of field experience. He is known for combining field data with remote-sensing measurements.

Prof. Sinha is an expert in sediment-transport processes and paleoclimatic reconstruction with more than three decades of experience in the Himalaya. He has worked on the impact of Quaternary and Holocene climate changes on sediment-transport processes and stratigraphic development in various parts of the Himalayan foreland basin.

Quaternary to present-day climate changes have profoundly altered the Himalayan landscape and have been a key driver for erosional processes. The rates of mass transport have changed throughout the past climate cycles - and with it the pace of landscape evolution. The goal of this symposium is to explore the interactions among climate variability and landscape evolution at a variety of scales: Spatial scales ranging from local studies to assessments encompassing the entire Himalaya, and temporal scales of days, seasons, to millennia at various points during the Quaternary. We solicit abstracts using observational and modeling studies, for example to explore: (1) the impact of (hydro-)climatic extreme events on sediment-transport processes, both in the past and present; (2) geo- and bio-geochemical tracer studies to reconstruct paleoenvironment conditions, sediment dynamics, and rates of transport etc.

Prof.Bhatla has been conducting research using RegCM.

Dr.Coppala has been contributing to developments in RegCM and further instrumental in CORDEX.

Although the climate change is a global phenomenon, its impacts are felt at the regional and local levels. So far as the impacts of climate changes on the society are concerned, the crucial issues are water resources, agriculture and human health. The related important climatic parameters are the surface temperature, relative humidity and rainfall. It is very important to have accurate information on the spatio-temporal distribution of these climatic parameters and their future projections in order to be able to estimate the impacts of climate changes on agriculture and human health at any place. This information also helps in appropriate policy formulation and adaptation measures. Both statistical and dynamical downscaling techniques can be judiciously used to get spatio-temporal distribution of relevant climatic parameters at any place which will be eventually useful in the context of global changes.

22.1 Advances in Our Understanding of Global Hydro-Climate Dynamics Before Cenozoic
Robert A Spicer r.a.spicer@open.ac.uk (UK), Vandana Prasad (India)

Prof Robert (Bob) Spicer current research spans two areas of ecosystem and climate evolution critical to understanding and managing global change issues. The first is landscape and monsoon evolution in southern Asia. The second is the evolution of high latitude vegetation and climate.

Dr Vandana Prasad is a Senior Scientist at BSIP-Lucknow, India with interest in High resolution biostratigraphy, biotic turnover, paleoenvironment, relative sea level change and paleomonsoon

It is being increasingly realized that broader understanding of present day regional monsoon dynamics can be better achieved from its global perspectives. Although, regional monsoons are recognized as a global system, each subsystem has its own features and patterns of variability on different time scales. The concept of global monsoon hinges upon the annual variation in precipitation and circulation in the global tropics to subtropics and annual migration of ITCZ. Emerging evidences have suggested that modern monsoon sub-systems were established in late Cenozoic after reorganization of land and sea. There has been growing interests in recent years in paleomonsoon studies across the world for the time interval prior to the Cenozoic, This symposium invites contributions on: Origin and Evolution of global monsoon system (prior to Cenozoic) in time and space and its driving factors. Nature and pattern of global Hydro-climate system (mega-monsoon) during Permian to Jurassic (Pangaea supercontinent). Modeling of large-scale meridional migration of the ITCZ over Pangaea. Causes for differences in the origin and evolution of modern regional monsoon systems.

22.2 Evolution of Monsoon Variability on Tectonic Scale During the Cenozoic

Dr Ann Holbourn is research scientist at Kiel University, Germany. She investigates the evolution of ocean circulation and climate on various timescales from the Cretaceous to the present and us interested in understanding the mechanisms driving changes in ocean productivity, temperature, oxygenation, ice volume and carbon cycling. Her research is primarily based on the geochemical analysis of foraminifera and marine sediment properties.

Dr. Raj K. Singh is Assistant Professor in School of Earth, Ocean and Climate Sciences, Indian Institute of Technology Bhubaneswar. His research interest focuses on understanding the evolution of Asian Monsoon system and its variations in longer (orbital scale cyclicity) and shorter (solar cycle) time scale. Dr. Singh has innovatively used deep-sea benthic foraminifera and planktic foraminifera to understand this monsoon variability.

Monsoon climate has varied through geologic time due to orbital parameters and tectonic processes resulting openings/closures of oceanic gateways, upliftment of mountains and position of continents. The tectonic processes operate over time spans > 106 years. Monsoon history at tectonic time scale traces back beyond the Quaternary. Over recent decades, there has been rapid advances in paleomonsoon reconstructions based on marine and terrestrial proxy records, in order to better understand climate-tectonic coupling. It is also believed that climate-driven erosion can also influence tectonism and the mountain belts architecture. However, it is essential to understand how the tectonic processes and climate-driven erosion interact and feed-back on each other in order to test and quantify linkages among them. In recent years, the International Ocean Drilling Programs (IODP) were taken up to study the pattern of variability in regional monsoon systems on tectonic, orbital and suborbital scales. This symposium invites contributions on (1) Origin, evolution, pattern variability and controlling factors of regional monsoon sub-systems on tectonic scale (2) Nature of the monsoon sub-system variability patterns from Paleogene to Neogene. New advances in tectonic scale monsoon evolution from recent IODP Expeditions (Expeditions 346, 253, 354, 355, 356, 359, 363).

22.3 Monsoon Evolution Pattern on Orbital to Suborbital and Centennial to Interdecadal Scales Stephan Steinke ssteinke@xmu.edu.cn (China), Sushant Naik (India)

Prof. Stephan Steinke is a palaeoceanographer, paleoclimatolgists and micropalaeonologitst specializing in past climate change with an emphasis on the mid- and low-latitude climate, particularly in the following areas: South and East Asian monsoon variability and Indo-Pacific Warm Pool hydroclimate. He is currently an Professor at the Department of Geological Oceanography and State Key Laboratory of Marine Environmental Science (MEL), Xiamen University, China.

Dr. Sushant Naik is a paleoceanographer and paleoclimatologist with keen interest in past climate change with emphasis on utilizing foraminifera for deciphering paleomonsoon, past pCO2 and pH. He is a Scientist with the National Institute of Oceanography, at Goa, India.

An understanding of the dynamics of regional monsoon variability and its relationship with other climate components is essential to our ability to predict monsoon, in the context of rapid climate change scenario. Paleomonsoon records from both marine and terrestrial archives from tropical-subtropical regions have shown variations in monsoon climate on orbital, millennial, and centennial to decadal scales. However, atmospheric and oceanographic processes involved for these changes and phase relationship (leads/lags) between these processes are not fully understood. Evidences suggest that apart from external orbital forcings and solar control, millennial to centennial scale changes in monsoon system are linked to the high latitude northern Hemisphere climate. Furthermore, there are strong evidences suggesting linkages between short term decadal scale monsoon variability and tropical Indo-Pacific climate and ENSO. We invite contributions on paleomonsoon studies made through various proxies from marine and terrestrial archives and recent IODP expeditions and modeling studies. The contributions are expected to address: External and internal climate forcing factors controlling monsoon variability. Short term variability and its linkages to internal climate variability such as high latitude climatic perturbations, inter-hemisheric climate relationships, atmosphere-ocean teleconnections, high and low latitude climate linkages (e.g., North Atlantic Oscillation, Atlantic Meridional Oscillation, El Nino Southern Oscillation, and Indo-Pacific oscillation/Pacific decadal oscillation).

She received her Ph.D. in Engineering (2016), MS in Earth and Build Environmental Science and Engineering from Xi’an Jiaotong University (2014) and an additional MS in Geological Science from Kumoun University, Nainital (2006) respectively. The main focus of her current research is on the hi-fidelity reconstruction of the Indian summer monsoon variability on a wide range of temporal and spatial scales to understand the past, present, and future of climate change using speleothem as the proxy.

Dr. Prosenjit Ghosh is Assistant Professor at the Centre for Atmospheric and Oceanic Sciences, Indian Institute of Science in the year 2007. His research interest focuses on reconstruction of seasonality through time using empirical relationships between the proxy records and climate parameters, and application of stable isotope technique to understand environmental processes. Most notable contributions have been the establishment of clumped isotope thermometry, generating standards for mass spectrometric analysis of solids and gaseous CO2 in air mixture, application of isotope based GCM to study Indian Monsoon precipitation.

Previously the climate variation in the Holocene was considered relatively much lesser to that of the last glacial period. Recent studies provide strong evidences of high amplitude, multidecadal to centennial scale variability of monsoon climate during the Holocene, associated to sunspot activity and also to abrupt reorganization of the thermohaline circulation. As there is strong relationship between the Holocene monsoons and human civilization, the interests in understanding Holocene monsoon variability and its causing factors have increased among the scientific community particularly in context of current scenario of anthropogenic induced greenhouse gases and global warming. The contributions are invited on various aspects of Holocene Monsoon such as variability patterns as recorded from marine and terrestrial archives, geoarcheological sites, documentary resources. Human adaptations to past monsoon changes. Evaluation of magnitudes of natural and anthropogenic forcings. Identifying past climate analogues projecting the future. Projected changes in the monsoon (ocean-atmosphere coupled models and earth system models).

Megadroughts are spatially extensive droughts lasting decades and perhaps even centuries. Megadroughts have repeatedly challenged the resilience of many ancient and medieval cultures and radically altered their historical trajectories. Indeed, a near-global megadrought 4,200 years now marks the most recent unit of Holocene. Decades-long drought in the Sahel during the latter half of the 20th century and in the SW United States in recent decades comprise modern examples of megadrought--but they pale in comparison to the earlier Holocene megadroughts documented by a global array of high-resolution proxy records. Nevertheless, the underlying and complex causal mechanisms of megadroughts remain poorly understood. We invite contributions that characterize the spatio-temporal pattern and magnitudes of megadroughts and strive to understand their causal mechanisms using instrumental observations, paleoclimate proxy records, and climate modeling. We also welcome contributions that investigate the societal impacts of past, present, and future megadroughts.

23.1 Carbonatites and Alkaline Rocks: Origin and Evolution with Special Reference to Rare Metal and REE Mineralisation
Anton R. Chakhmouradian chakhmou@cc.umanitoba.ca (Canada), P. Krishnamurthy (India), S. G. Viladkar (India)

Dr. Anton R. Chakhmouradian obtained his doctoral degree on geology and mineralogy in 1997 from St. Petersburgh Univ. Russia. Following post-doctoral studies at Lakehead University, he joined the Univiversity of Manitoba in 2000 and is engaged in teaching and researches focused on the petrology, mineralogy and geochemistry of carbonatites, alkaline rocks and related-mineral deposits. A recipient of the Young Scientist award (2005) of the Min. Assoc. of Canada and also the W. W. Hutchinson Medal of Geol. Assoc. of Canada (2011).

Dr. P. Krishnamurthy is engaged in researches on carbonatites, Deccan Basalts, Uranium Geology and Rare Metal Exploration (carbonatites), both in the field and supported by robust analytical capabilities in XRD, XRF and EPMA at Centre of Advanced Study in Geology, Dr. HarisinghGour Central University (1966-70; 1974-75), University of Edinburgh (1970-74) and AMD (1975-2003). Presently continuing to train Research Scholars and Faculty in Indian Universities with special reference to carbonatite RM & REE related mineral resources in India, jointly convened by Geological Society of India and AMD since 2015).

Dr. S. G. Viladkar is engaged in teaching and researches of carbonatites of India with special reference to AmbaDongar at the St. Xavier’s College, Mumbai, since 1967, through International collaboration with scientists from Canada, USA, Germany (Alexander Von Humboldt Fellow), Russia, South Africa and UK. Presently engaged in researches on carbonatites at the CRC,  AmbaDongar.

Carbonatites are rare rock types that host rare metal and rare earth element (RM & RE) deposits, which are critical to the development of high-technology applications from cell phones to supercomputers. An understanding of their genesis and evolution with special reference to the mantle source regions to the formation of a deposit is vital for exploration and exploitation. Ever since the proving of the existence of ‘synthetic carbonatite magma’ by experimental studies in the CaO-CO2-H2O system and its corroboration by the eruption of carbonate-lavas with nephelinites in OldoinyoLengai, Tanganyika in 1960, there has been an exponential increase in researches on carbonatites and associated alkaline rocks. Physico-chemical and mineralogical evolution of the carbonatite magma within a given complex is thus vital to ore body location and search.

The Symposium aims to invite abstracts on carbonatite research, especially works those inter-linked the theory and practice that will be a potential help in exploration so that ore body models are refined and which may also lead to better focus on deposit-seeking techniques and approaches. Those who had worked on proven deposits can be specially sought to contribute to the Symposium.

Yasushi Watanabe, graduated from Hokkaido University, worked for Geological Survey of Japan for 29 years.

Kenzo Sanematsu, graduated from Kyushu University and has been working for AIST.

There are wide spectrums of rare earth resources in addition to carbonatites which dominate in LREE. These include non-alkaline-rock related deposits, iron-oxide apatite deposits, phosphate-rich hydrothermal deposits, ion-adsorption deposits, placer deposits, deep-sea sediments, etc. Although the rare earth grades of these deposits are lower than those of the carbonatite deposits, some of the deposits are enriched in HREE, and from some deposits, REE may be produced as a by-product. This symposium aims to discuss the geneses of these REE deposits including transportation and concentration processes of REE in these deposits. This symposium will also discuss geometallurgy of REE of these deposits; how efficiently and feasibly REE could be extracted from the ores.

23.4 Critical Raw Materials for Sustainable Development: Geology, Resources, Production and Socio-Economics
Harikrishnan Tulsidas harikrishnan.tulsidas@un.org (Switzerland)

Harikrishnan Tulsidas is a professional geologist with over 30 years of experience in management and development of critical raw material and energy resources. He has wide experience in exploration, resource evaluation, development, process innovation, and international policy formulation. He currently works as Economic Affairs Officer in the United Nations Economic Commission for Europe (UNECE) and leads the work on development of global standards for sustainable management of critical raw materials.

Many hi-tech applications including high efficiency, energy conserving, less-polluting and low-carbon technologies of the future such as renewable energy, e-mobility, communications, data management, robotics and artificial intelligence require vast amounts of critical raw materials (CRM). Such CRMs are not only essential for the green technologies, but also for more basic objectives of sustainable development such as food production, healthcare and water desalinisation.

Geological understanding of its occurrence and associations were often ignored even when they were found with other high-value materials like iron, copper or gold ores. Some of these materials are associated with refractory minerals. Hence the current technologies for recovery are energy- and chemical-intensive harsh processes involving higher levels of radioactivity.

This symposium aims to discuss CRMs based on the demand and supply analysis; its sustainable production and utilisation. This symposium intends to connect global geological surveys and service organisations, the mining industry and technology providers to meet the objectives of 2030 Agenda for Sustainable Development and beyond.

Keywords: CRM, ECE Resources and Sustinability

23.5 Critical Metal Deposits and New Technology
Shao-Yong Jiang shyjiang@cug.edu.cn (China)

Prof. Shao-Yong Jiang has major interests in Ore genesis of the critical metal deposits; petrogenesis of magmatic rocks; stable and radiogenic isotopes and their application in mineral deposit research and in geochronology.

Critical, strategic, Hi-tech or green metals include (but are not limited to) the rare earth elements, Nb, Ta, Li, Be, Rb, Cs, Zr, Hf, Co, In, Ge, Ga etc. The rapid development of new technologies has led to the increasing demand for these critical metal resources, yet the potential primary and secondary sources of a number of these elements remain somewhat poorly understood. In particular, comparatively little research has been undertaken on the genesis of the diversity of critical metal deposit types, the geochemistry and cycling of these elements. This symposium provides an opportunity to discuss the most recent research into understanding critical metal deposits. Contributions focused on geochemistry, mineralogy, genesis and the exploration of critical metal deposits are encouraged. Topics will encompass the new and novel understanding of traditional ore deposits from multiscale datasets, possibly taking advantage of the recent developments of high spatial resolution techniques for in-situ chemical and isotope analysis.

Keywords: Critical, Strategic, Hi-tech, Green metals; Ore-genesis; Exploration

23.6 Raw Materials for the Electric Vehicle Revolution: Geology, Mineralogy and Geometallurgy
Kathryn Goodenough kmgo@bgs.ac.uk (UK)

Dr Kathryn Goodenough is a Principal Geologist at the British Geological Survey. Her research focuses on the geology of critical metal resources, particularly the rare earth elements and more recently lithium, and she is involved in a number of international collaborations on this topic.

Modern technology, including low-carbon technology such as renewable energy and electric vehicles, is dependent on a wider range of raw materials than ever before. In particular, growth in electric vehicle (EV) use is expected to drive demand for a range of raw materials used in batteries and motors, particularly including cobalt, lithium, the rare earth elements, nickel, and manganese. Most of these commodities are currently mined from a relatively limited number of deposits worldwide. Improved understanding of the geology, mineralogy and geometallurgy of these deposits is vital to ensure secure, sustainable supply of these raw materials. This symposium invites presentations on all aspects of the life-cycle of these EV raw materials, from geological context and exploration for resources, to mineral processing and metal recovery. Presentations are welcomed on both onshore and offshore deposits, and on both primary and secondary resources.

Keywords: electric vehicle, cobalt, nickel geometallurgy

23.7 Mineral Processing Technology for Cleaner Production of High-Tech and Critical Metals
T Sreenivas tsreenivas@ymail.com (India), Abhilash (India)

Dr T Sreenivas is a Senior Scientist working for last 30 years in the field of mineral processing of strategic and critical metals. He is also Professor in Homi Bhabha National Institute and recipient of National Geoscience Award with about 100 publications in peer reviewed journals and International Conferences.

Dr Abhilash is a Scientist working for last 14 years in the field of hydro-biohydrometallurgy of strategic and critical metals vis-a-vis recycling of secondary resources. He is Member, National Academy of Sciences (India), and recipient of Young Scientist Award (BRSI, AMI, ISCA, MESA, INSA), Young Metallurgist Award (Govt of India) with about 80 publications in peer reviewed journals and International Conferences.

As countries gear-up for endowment of natural resources of high-tech and critical metals which are essential components in green technology materials, it will be critical that various facets of sustainability are integrated into new operations, policies and investments. Elimination of waste and reduction of energy consumption reduce both the demand for new mineral resources and quantities of potentially harmful wastes and contribute to the transition to sustainability. These challenges provide opportunities for the application of mineral processing and extractive metallurgical principles to add value to wastes/co-products, reduce energy consumption and recycle complex and novel materials besides harnessing primary and secondary resources. Many of the geological settings of high-tech and critical metals are in complex environment with reference to their beneficiation and hydrometallurgical processing. In most cases they are by- or co-products of some other major minerals/metals or the tenor may be very lean demanding comprehensive extraction approaches for making their recovery economical and environmentally benign. This Symposium focuses on mineral processing and extractive metallurgy for cleaner production of high-tech and critical metals with active participation by way of Invited lectures and contributory papers from industry, academia and research organisations.

23.8 Pegmatite: Mechanism of Emplacement, Genesis, Deposits and Economic Significance
M.B. Verma director.amd@gov.in (India)

Shri M.B. Verma is the Director of Atomic Minerals Directorate for Exploration and Research in India and has more than 35 years of experience in exploration for U, RM and REE hosted in various rocks including pegmatite.

Pegmatite is a textural attribute rather than composition, where exceptionally coarse size of crystals develops in a variety of physiochemical conditions from a crystallising magma. Granitic bulk composition pegmatites are common however, mafic, alkaline rocks and carbonatitic pegmatites do occur in nature with different suites of minerals.
The role of aqueous vapour phase and growth rate of silicate crystals in pegmatites are the important field of research in experimental igneous petrology. The mechanism of pegmatite emplacement and chemical zonation are other equally important aspects, which need to be addressed. The transfer process of elements in giant crystals is another field of research. This symposium intends to discuss all these aspects Besides, the symposium also aims to give due importance to genetic aspects of REE, Rare alkalies- Li, Rb and Cs, Rare Alkaline Earths- Be, Sr and Ba, High Field Strength Elements including Sn, Nb, Tq, Zr, Hf and Fluxing Components B, P, and F. The relation of LCT and NYF pegmatite to the S, I and A type granite is another major scope of this symposium.

24.1 Spatio-Temporal Variability of Carbon Burial in the Oceans
Rajeev Saraswat rs.niog@gmail.com (India)

Dr. Rajeev Saraswat is working as Senior Scientist in the National Institute of Oceanography, Goa. His research interest includes paleoclimate and paleoceanography.

Oceans are a large sink of carbon. The ocean sediments contain both inorganic and organic carbon. The abundance of organic and inorganic carbon in marine sediments mainly depends on primary productivity, sediment grain size, dissolved oxygen concentration and depth. As the aforementioned parameters vary regionally, the carbon burial also varies accordingly. Additionally, the temporal variability in these parameters results in a change in carbon burial potential of any region. The assessment of both the spatial and temporal variability in carbon burial in a region is important to understand its potential to modulate global carbon cycling during different boundary conditions. This symposium invitites contributions on documentation of carbon burial during both the present and past, in different parts of the world oceans.

24.2 Assessing Coastal Vulnerability in a Warming World
R. Mani Murali mmurali@nio.org (India)

Dr. Murali is a Senior Scientist in the National Institute of Oceanography, Goa. His research interest includes coastal processes and coastal vulnerability.

A large human population resides in the coastal regions of the tropical countries. The rise in sea level, as well as extreme oceanic events like cyclones, Tsunami and Surges have increased the vulnerability of the coastal regions. Some of the appropriate climate changes and their impacts include accelerated sea-level rise, the increase in the number and intensity of coastal and inland storms, coastal inundation associated with increased precipitation and shoreline erosion. The vulnerability of different coastal regions, however, varies, depending on the elevation of the settlement zone, as well as intensity and frequency of extreme events. The increase in the frequency of extreme events will thus have grave consequences in the form of loss of life and property apart from the adverse effects on the coastal ecosystems. This symposium aims to include remote sensing, modelling and field studies based on approaches to assess the vulnerability of different coastal regions to anthropogenic activities, as well as sea level and extreme events.

Dr. Biswas is working as a Senior Scientist in the CSIR National Institute of Oceanography, Biological oceanography Division, Goa. Her research interest includes ocean biogeochemistry and the effects of ocean acidification on marine phytoplankton.

Dr. Shetye is working as a Scientist in the CSIR National Institute of Oceanography, Goa. His research interest includes ocean biogeochemistry and the effect of ocean acidification on calcareous marine organisms.

Dr. Dineshram is working as a Scientist in the CSIR National Institute of Oceanography, Goa. He had extensively worked in experimental marine ecology to study climate change impacts on marine invertebrates at physiology and proteomics levels.

Over the last century, extensive anthropogenic activities on earth led to an unprecedented increase in the atmospheric CO2 concentration and thus warming our climate. The surface oceans absorb a substantial part of the anthropogenically emitted CO2 and increased accumulation of CO2 in the surface ocean waters is increasing H+ and bicarbonate ion (HCO3-1) concentrations, coupled with decreasing pH [acidification (OA)] and carbonate ion (CO3-2) concentrations. The major shift in dissolved inorganic carbon speciation in surface seawater is affecting calcium carbonate saturation state, which is vital for numerous marine calcifying organisms. There have also been examples of resilient species under low pH condition. Autotrophic organism, like phytoplankton may respond differently to this ocean changes since increasing CO2 may be beneficial to them as a substrate for photosynthesis. Our oceans also experiencing warming and hence, under collective (multi-) stress may become deleterious for marine biota. Further, ocean warming is resulting in major changes in ocean physics which may further change nutrient availability and light penetration. These may have potential to impact the entire food chain, fisheries resources and carbon cycling. This symposium intends to include field and laboratory studies on extent of ocean acidification and its impact on marine ecology, with particular emphasis on Indian waters.

24.4 Reconstructing Past Pollution Levels from Marginal Marine Regions
G.N. Nayak gnnayak@unigoa.ac.in (India), Rajiv Nigam (India)

Prof. G. N. Nayak is working as Professor, in the Department of Marine Science, Goa University, Goa. His research interest is pollution monitoring and paleoclimate reconstruction.

Dr. Rajiv Nigam is working as Emeritus Scientist, in the National Institute of Oceanography, Goa. His research interest is application of foraminiferal proxies.

Anthropogenic activities result in discharge of various pollutants in the marginal marine regions. The pollutants include heavy metals, persistent organic pollutants and sewage. These pollutants adversely affect marginal marine community and thus severely alter the ecology of the marginal marine regions. The high resolution past records of concentration of various pollutants, can help in assessing the timing and possible anthropogenic activity responsible for increasing pollutant load. This symposium intends to include papers based on the past records of pollutants from marginal marine regions.

24.5 Sea Level Changes During Late Pleistocene and Holocene Periods and its Implications of Coastal Landforms.
V.J. Loveson vjloveson@nio.org (India)

V.J. Loveson is working in sea level changes research for nearly 28 years. He elaborately studied the Quaternary sea level variation along East Coast of India. During 1995-99 Inter-congress periods, Dr Loveson functioned as Secretary, INQUA Indian Ocean sub-commission on Sea level variation and coastal evolution.

The rise in sea level is an important effect of global warming. The rate of sea level rise, however, varies regionally, due to the local upliftment/subsidence. Besides, natural variability also affects sea level. Therefore, it is important to delineate the natural and anthropogenic contributions to the sea level changes. The past sea level change records from different regions can help in delineation of natural and anthropogenic contribution to the sea level in a warming world. This symposium aims to include modelling and field studies to reconstruct past sea level changes from different parts of the world.

Geoarchaeology is a study of archaeological record and can be applied to a wide range of scales, from the reconstruction of palaeoenvironments and how they have been affected by human activity. Geoarchaeological research includes both geological and archaeological practices and converges into a single discipline with specific characteristics, aims, and procedures. Undoubtedly, the effective integration of the earth and archaeological sciences is one of the major challenges of geoarchaeology.

An integration of invasive viz. archaeological excavation and noninvasive approaches viz. application of geospatial techniques, maps for geological-geomorphological analysis, geophysical surveys, use of available natural resources etc. may help in the process. Coring of sediment section undoubtedly constitutes one of the most common methodological approaches employed by geologists and archaeologists in reconstructing subsurface stratigraphic architecture. This symposium is planned to address all aims and challenges of geoarcheology in varied situations.

25.2 Late Quaternary Climate Shifts and Human Adaptation to Landscape: A Geoarchaeological Approach
Hema Achyuthan hachyuthan@yahoo.com (India)

Dr. Hema Achyuthan has keen interest in understanding man land relationship and his adaptation to late Quaternary climate shifts.

During the Late Quaternary period, climate has fluctuated several times with varying intensity and duration. These shifts have affected civilisations, causing their decline and collapse such as the Harrapan, Sumerian, Akkadian, since the mid-Holocene period or even older Man’s communities. Application of geological methods to archaeological sites, especially of the stratified archaeological deposits have yielded a wealth of information and records of vegetation change reflecting both geomorphic and past climate events and the utilization of plant resources by Man. Changes in composition of charred wood, fruit, and seed assemblages indicate the progressive impact of man upon the native vegetation during the late Quaternary to Holocene period. Man has experienced Late Quaternary climate shifts, has adapted and settled on the land. Land clearance and cultivation over the past several thousands of years have increased the extent of forest edge, the transition zone between closed forest and open areas. These changes have led to an increase in landscape carrying capacity, in the abundance, and diversity of food resources available to expanding populations. Paleoenvironmental and paleoecological analyses of palaeosols, sediments from lakes, sediment detritus from archaeological sites, coastal sites, sites within the river banks, ocean cores that will be correlated with terrestrial and climate events. This symposium will bring together researchers who will deliberate on their findings.

Parth R. Chauhan: Assistant Professor at IISER Mohali; Specialising in prehistoric archaeology of central India and northern India. Carries out paleoanthropological research on stone tool technology, geoarchaeology and vertebrate palaeontology.

This session focuses on the investigation of adaptations among hominins to local, regional and global environmental changes during the Pleistocene and early Holocene, ranging from the Palaeolithic to the Neolithic/Chalcolithic cultural phases. These periods document the existence of a diversity of hominins and feature evolutionary processes which eventually allowed modern humans to flourish and their technological agencies to prevail. Accordingly, some major transformations in prehistoric cognition and behaviour occurred, and research in recent years on these questions has yielded new perspectives on the chronology and patterns of hominin dispersals across the world, and on the characteristics of cultural phases and transitions. Such important insights have typically been gained from advances in geoarchaeological methods and geochronology; from anthropological models; from approaches to inferring cognitive skills and behaviour based on artefact assemblages; and from a deeper understanding of correlations between fossil, genetic and archaeological data. We would welcome contributions on any of these topics, in hope that they will collectively sharpen our continuously changing conceptions of the past.

25.4 Recent Scientific Methods In Coastal And Inter-Tidal Archaeology
Supriyo Kumar Das sdas.geol@presiuniv.ac.in (India), Kaushik Gangopadhyay (India)

Dr. Supriyo Kumar Das, an Organic Biogeochemist with international portfolio, is working to address fundamental geoarchaeological problems by applying geochemical methods.

Dr. Kaushik Gangopadhyay is an experienced and trained environmental archaeologist, and is working in coastal West Bengal since 2006. He and his team have excavated two sites in east Medinipur district in West Bengal.

Coastal and inter-tidal archaeology have emerged as one of the major subdisciplines within the field of archaeology in recent years. Coastal areas have been colonized by humans from the prehistoric period because of the presence of easily exploitable marine as well as terrestrial resources. Therefore, there is a need to develop inter-disciplinary approaches to understand the archaeological records preserved in the dynamic and varied coastal landscapes. These landscapes include coastal sand dunes, basins of tide dominated estuaries, islands and swamps. The symposium will address methodological challenges of studying coastal geoarchaeology, and its link to site-formation processes. Stratigraphy of a coastal sites is affected by sea-level changes, burial and erosion processes. These dynamic mechanisms have direct impact on the preservation of archaeological sites. Archaeological artefacts and objects such as bones are modified as a result of dynamic processes of water actions. Transport of objects into secondary contexts is common occurrences thereby making cultural interpretations difficult. These can be addressed as formation process of the archaeological site. Scientific methods adapted from geology, for example, studying the roundness of fluvially-transported clasts would be useful in such conditions. The session will also address challenges in dating coastal sites, and the usefulness of combining multiple dating techniques such as AMS radiocarbon and OSL. The session will further address modern tools in geoarchaeology including organic residue analysis and the application of stable isotopes and lipid biomarkers in reconstructing the anthropogenic history in archaeological record.

The symposium calls for contributions on early earth orogenesis centering on when, how and why did the "modern-style" plate tectonics begin on the planet earth. Despite divergent opinions, there is a general consensus that the switch over from "pre-subduction", plume-driven vertical tectonics to "modern subduction" regime of horizontal plate motions is linked with a change in thermal regime from one of heat generation through radioactive decay to heat loss by conductive cooling. The tectonic transition that is said to coincide with the first appearance of an arc-back arc system, the earliest record of eclogite, the advent of a dual thermal regime, reflecting unequivocal convergent plate margin processes and changes in crustal growth rate and petrotectonic assemblages (e.g. from tonalite – trondhjemite to potassic granites and from mafic, komatiitic greenstone belts to less mafic ones) appears to have taken place in the time period between 3.2 and 2.8 Ga. We encourage theoretical, high-precision analytical, experimental and fieldbased contributions from the fields of metamorphic petrology, geochemistry, geochronology, diffusion chronometry and thermo-mechanical modelling, primarily addressing "early Earth" tectonic processes. The session focuses on studies from low- to high-grade Archaean to Earliest Palaeoproterozoic metamorphic terrains in a range of topics from phase equilibria modelling, metamorphic P-T-t paths, timescales of orogenesis to geochemical and isotopic fingerprinting of tectonic settings.

Convergent plate margins are sites of intense deformation, magmatism, and metamorphism, where significant heat, fluid, and mass transfer may take place during orogenesis. Quantifying the fluxes and drivers of such processes during plate convergence is critical to understand the geodynamical evolution of the lithosphere, the rates and mechanisms of metamorphism at elevated pressure and temperature conditions, and for constraining the nature of mountain building through geological time, whether collisional or accretional in nature.

This symposium seeks contributions that investigate the causes, effects, and petrological or tectono-thermalimplications of regional or contact metamorphism at convergent margins, focusing on continental crustal materials. We welcome and encourage abstracts that use a variety of techniques, such as field mapping, phase equilibria modeling, petrochronology, geochemistry, and geodynamic and/or geophysical modelling, and studies that span a wide range of spatial and temporal scales.

Pulak Sengupta, Professor at Jadavpur University, 20 years of research experience on ultrahigh temperature metamorphosed rocks of India, over 35 research publications on the subject, Bhatnagar awardee, Fellow of Indian National Science Academy, Indian Academy of Sciences and Alexander von Humboldt Foundation.

Crustal metamorphism with peak temperatures exceeding 900°C, and locally reaching 1000°C or more, first documented from the Napier Complex about half a century back, is an established phenomenon. Recent compilations show more than 60 such UHT terranes the world over. Major advances have been made in recent years towards understanding the cause(s) of extreme thermal perturbation mostly at lower crustal levels and the possible tectonic scenarios. Discovery and calibrations of new trace element geothermometers improved measurement of temperatures, and phase equilibria modeling helped to document peak thermobaric conditions, P-T path of evolution, role of melting and melt segregation, collectively indicating possible tectonic environments. Improved geochronological techniques, particularly at such high temperatures, provided constraints on both timing and duration of UHT metamorphism. UHT metamorphosed terranes provide important clues regarding supercontinent assembly in the geological past. Despite these advances, major outstanding questions remain: (a) how efficient are the trace element geothermometers ?, (b) is UHT metamorphism short-lived and repetitive or long-lived ?, (c) what is the role of melt segregation in preservation of UHT assemblages? , (d) how efficient is the pseudosection approach in phase equilibria modeling, given the inherent uncertainties in bulk chemical approximation (water content and effect of melt segregation)?, (e) what is the significance of diverse kinds of retrograde P-T paths in terms of tectonic settings? (f) what is the rate of uplift and exhumation of UHT metamorphosed lower crust? The above points are illustrative, but not exhaustive. Given that several UHT metamorphosed terranes have been described from India, the symposium is expected to draw wide attention both nationally and internationally.

Fellow of Mineralogical Society of America, Fellow of Geological Society of America,Academician of Chinese Academy of Sciences.

A dramatic increase in current research on HP- and UHP- metamorphism reflects their significance in deciphering lithosphere evolution, and 30-35 years after the first discoveries of coesite and diamond in metamorphic rocks we now have completely different view on processes such as mantle dynamics, crustal tectonics and fluid-rock interaction during subduction, collision and exhumation, crust-mantle interaction in subduction zones. Recently a completely new field of research has also developed as a result of the discoveries of UHP minerals and assemblages in ophiolitic bodies in Tibet (Luobusa) and the Polar Urals (Ray-Iz).

Many of these new findings triggered further experimental studies and modeling; intensified future research should allow a better understanding of processes such as the subduction of oceanic and continental lithosphere, recycling of surface carbon and fluids to mantle depths, and later ascent towards the Earth’s surface.

This session welcomes contributions from small scale observations, for instance using X-ray, FTIR, Raman, TEM, Laser ICP-MS, SHRIMP, etc. techniques, to mountain forming process that include field studies, the derivation of pressure temperature paths, geodynamic modeling, geochemistry as well as age dating and fluid inclusion studies. We appreciate not only abstracts related to natural rocks but also to HP/UHP related experiments.

Research interests in subduction-zone mineral transformations, in particular fluid-mediated processes. Author of twenty five publications, Associate Editor for American Mineralogist

Whilst critical for our understanding of subduction zone geodynamics and related hazard, the nature, structure and properties of the subduction plate boundary are still largely unknown. Determining which lithologies and rheological behaviours prevail, which are the fluids and where, or what is their exact bearing on earthquake ruptures remains a real challenge. Metamorphic rocks are increasingly used as probes to image and understand physical conditions and processes at work along the subduction boundary at all relevant spatial and temporal scales (i.e., years and meters across all depths). Mineral transformations tightly control both deformation and element transfer along the slab, to the arc and to the deeper mantle. We welcome in this session all contributions aiming at integrating structural, petrological, mineralogical and geochemical data with particular emphasis on bridging the gap between observations made at rock and plate scale, from millions of years to a few hundred years only, and with interest in relating these findings with geophysical or numerical modelling data.

27.1 Field Structures – Macro to Meso Scale Deformation Processes
Bernhard Grasemann bernhard.grasemann@univie.ac.at (Austria), T. K. Biswal (India)

Prof. Bernhard Grasemann from Vienna (Austria) has worked extensively in the Himalaya and has made fundamental contributions in Structural Geology.

Prof. T.K. Biswal is a well-established name in the field of Structural Geology with experience of working in Geological Survey of India as well as in academia (IIT Bombay, India).

Although sophisticated analytical instrumentation has taken over many aspects of high-resolution geological analysis, field geology remains to be the foundation of most structural geology investigations. Interpretations based on structures/fabric that are visible to the human eye in the field, continue to be the first step in the study of deformed rocks. From the unravelling of superposed deformation, to the analysis of strain, field studies have been of primary importance in structural geology. In today’s modern times, structural geology techniques in the field become more and more supported by useful tools like tablet computers, terrestrial laser scanners or unmanned aerial vehicles. India is blessed with a variety of deformed terrains ranging in age from Archaean (Dharwar, Singhbhum, Bundelkhand) through Proterozoic (Aravalli-Delhi, Eastern Ghats, Central India Tectonic zone, Southern Granulite belt) to Phanerozoic (Himalaya orogen). These are replete with shear zones, ductile and brittle structures and have been a centre of attraction for field studies by Structural Geologists from all over the world. Many fundamental aspects of structural geology have been established exclusively based on analysis of field structures in rocks of ancient and modern orogens like the Caledonides, Variscan or Alpine-type orogens. Many processes with implications to kinematics and large scale tectonics and geodymanics have been envisaged based on field structures. This symposium intends to invite abstracts on “Field Structures-Macro to meso scale deformation processes”. It is expected that this will attract structural geologists who use field data to infer processes in polydeformed terrains and carry out kinematics as well as dynamic analyses using orientations of visible field structures.

27.2 Rheology and Deformation Mechanisms in the Earth

Prof. Nibir Mandal (Jadavpur University, India) has worked extensively on experimental rock deformation and numerical modeling. His research has contributed significantly to understanding of geodynamic processes and rheology of earth.

Dr. Susan Ellis is a Principal Scientist and Geodynamic Modeller at GNS Science, New Zealand.
Dr. Joel Sarout is a Senior Research Scientist at CSIRO, Perth (Australia). He leads the Rock Properties team.

Dr. Santanu Misra (IIT Kanpur, India) has established an experimental rock deformation facility in his institute and has contributed significantly to the understanding of deep crustal processes.

The deformation of rocks in response to tectonic stresses (rheology) is largely controlled by their ambient conditions (frequency and amplitude of stress perturbation, temperature, presence of fluids etc.), physical properties of the rocks and many other geological factors, such as synkinematic mineral reactions. The processes involved in rock deformation can be observed at multiple scales through a variety of mechanisms, ranging from brittle micro-fracturing to large- scale tectonic faulting (seismic and/or aseismic slip), crystal-plastic creep, stress-induced solid- state diffusion, partial-melting, and fluid flow. Such processes play a critical role in governing the Earth’s deep-rooted dynamics, and shaping its surface morphology. This session on Rheology and Deformation Mechanisms is designed to present and discuss current research and knowledge of the diverse processes of Earth deformation, particularly emphasizing role of transient rheology and resultant structures at varied scales. The session will bridge studies from micro-mechanisms of crystal deformation to large-scale tectonics, shallow brittle faulting to deeper ductile flow, using evidence from theoretical, numerical, experimental and natural data and observations.

27.3 Fabric Analysis – Past, Present and Future
Rick Law rdlaw@vt.edu (USA),Toru Takeshita (Japan), Koushik Sen (India)

Prof. Rick Law from Virginia Tech (USA) has made fundamental contributions to the analysis of deformed rocks using crystallographic preferred orientations (CPO).

Prof. Toru Takeshita from Hokkaido (Japan) is well-known for the study of quartz CPO and their use in understanding deformation conditions.

Dr. Koushik Sen is a scientist at WIHG, Dehradun (India) who has done extensive fabric analysis using microstructures and anisotropy of magnetic susceptibility (AMS).

Fabric analysis is critical in deciphering mechanisms and microscale processes that operate in deformed rocks. Challenging problems such as identifying monoclinic vs. triclinic shear zones or host vs. recrystallized quartz grains require detailed investigation of microstructures and crystallographic preferred orientations (CPO). Microstructures are a direct indicator of the conditions of deformation (pressure/temperature/strain rate) and also provide geologists with kinematic information that can be eventually useful in interpreting larger scale structural and tectonic processes. Since the beginning of the 21st century, fabric analyses have been performed using both; 1) relatively recently developed techniques involving, for example, SEM-Electron Backscatter Diffraction (EBSD), SEM and Microprobe-based Cathodoluminescence, Transmission Electron Microscopy (TEM), Anisotropy of Magnetic Susceptibility (AMS), Computer-Integrated Polarization (CIP) microscopy and, now less commonly, 2) older techniques such as measurement of CPO by Universal Stage and X-ray Texture Goniometry. It is therefore prudent to bring together structural geologists who use different fabric-analysis tools and techniques under one roof. This will provide a platform for geoscientists from all over the world to look at fabric data from a variety of geological terrains and collected using different analytical methods. Moreover, this will provide an opportunity to discuss the pros-and-cons of different methods of fabric analysis, thus providing the present and future generation with a direction for their research.

Dr. T.K. Mondal is an Assistant Professor in Jadavpur University (Kolkata, India). He teaches Structural Geology and has contributed significantly to the understanding of vein emplacement and gold mineralization in Gadag region (Dharwar craton).

Mr. Sivaji Lahiri is presently a research fellow in IIT Kharagpur. He is the first person in India, and one of the few in the world, to have quantified state of stress using vein orientations.

Most crustal-scale fluid flow is strongly influenced by the stress state, fluid pressure distribution and pre-existing fractures/foliations. Studies on such aspects are important to decipher the mechanisms of the hydrothermal fluid flow that lead to the formation of economic and non-economic the vein and breccia deposits. Therefore, it is important to understand the mechanics of structural controls on fluid flow and mineralization. In this context, the integration of results from various research domains in earth sciences, structural geology, mineralogy, geophysics, geochemistry, modelling) is the pre-requisite to understand the mechanics of the complex processes responsible for fluid flow and mineralization. This session aims to bring together the communities working on crustal-scale fluid flow with the objective to promote a scientific interaction for understanding the role of geological structures in fluid flow and mineralization. We encourage the presentation of contributions (both oral and posters) showing how multi-methodological and multi-disciplinary approaches improve the knowledge of structural control on fluid flow and mineralization.

Dr. Virginia Toy (Otago, New Zealand) does extensive work on shear zones and faults for which she employs a variety of tolls including fieldwork and EBSD.

This symposium, entitled aims to provide a common discussion platform for experimentalists, modellers and field geologists. We observe geological structures, and from them, we aim to decode the rheology of the rocks and understand the geological processes involved in their formation. One of the ways by which we enhance our understanding of the processes and mechanisms that lead to the formation of structures in naturally deformed rocks is to explore deformation in the laboratory. These experiments may be analogue or computational. They are typically performed at relatively high strain rates with the results subsequently extrapolated to natural strain rates. We invite contributions from geoscientists carrying out relevant field and experimental studies, at various temporal and spatial scales, to help geologists appreciate the conditions that lead to development of various brittle and ductile structures. We also encourage contributions that explore the extrapolation of experiments to natural strain rates, to mineral assemblages (rather than single phase aggregates), and to rocks undergoing chemical reactions during deformation.

28.1 Magmatic Processes and Ore Deposits
Mei-Fu Zhou mfzhou@hku.hk (Hong Kong, China), Ibrahim Uysal (Turkey), J. Gregory Shellnutt (Taiwan), Shoji Arai (Japan)

Magmatic ore deposits (e.g., chromite, Ti-V-bearing magnetite, Ni-Cu-sulfides and PGE) are formed from ultramafic-mafic magmas due to high temperature crystallization processes. This symposium will cover the current state of knowledge and understanding of these deposits across the world, in particular of the deposits of chromite, Ti-V-bearing magnetite, PGE associated with chromitite and/or sulfides, and Ni-Cu-sulfides in mafic/ultramafic rocks including komatiites. This symposium invites contributions on the fundamental processes which control the formation of these deposits through space and time.

28.2 Hydrothermal Processes and Ore Deposits
Franco Pirajno franco.pirajno@uwa.edu.au (Australia), Nigel Cook (Australia),Guoxiang Chi (Canada), Reimar Seltmann (UK), Jingwen Mao (China)

The formation and development of hydrothermal mineral systems is a consequence of interaction of metal enriched fluids (from diverse sources) with a wide variety of host rocks. Circulation of hydrothermal fluids and their interaction with surrounding rocks, result in heat and mass transfers between the fluid and rock, which leads to precipitation of ore minerals and the formation of alteration zones surrounding the ore bodies. Field observations (ground truth) integrated with microscopy, chemical and isotopic analyses of ore and gangue minerals are essential in the understanding of hydrothermal ore forming processes. This symposium invites contributions covering various genetic aspects of broad deposit types such as (i) orogenic/intrusion associated gold, (ii) base metals, and (iii) Sn-W-rare metals (+REE).

28.3 Sedimentary Processes and Ore Deposits
Andrey Bekker andreyb@ucr.edu (USA), Nicolas J Beukes (South Africa), Harilaos Tsikos (South Africa), Carlos Alberto Rosière (Brazil), Joydip Mukhopadhyay (India), Bertus Smith (South Africa).

A number of mineral deposits are hosted in sedimentary rocks. Sedimentary processes are responsible for the origin of these ore deposits (e.g., placer deposits, phosphorites, bauxites, Fe and Mn deposits, evaporites); alternatively, sedimentary rocks could behave as a trap for mineral enrichments (e.g., Cu-stratiform deposits, U rollfront deposits) due to their variable redox state. Significant progress has been made in our understanding of sedimentary processes responsible for ore deposits and the origin of sediment-hosted ore deposits. This symposium invites contributions and proposals for technical sessions dealing with processes responsible for sedimentary and sediment-hosted ore deposits are solicited for this symposium.

28.4 Fluid/Melt Inclusions, Trace Element and Isotope Geochemistry in Study of Ore Deposits
Robert Bodnar rjb@vt.edu (USA), Svetlana Tessalina (Australia),Maria Luce Frezzotti (Italy), John Mavrogenes (Australia)

Fluid/melt inclusions, trace elements and isotope geochemistry are the indispensable tools in ore deposits studies, unravelling the details about timing of ore emplacement and ore forming processes. This particular symposium will be focusing on two major aspects such as (1) Fluid/melt inclusions in ore deposit studies and (2) Application of isotopes in ore deposits studies. One of the major focuses will be on their applications in ore exploration.

28.5 Solubility of Metals in Melt/Fluid Systems
Anna Vymazalová anna.vymazalova@geology.cz (Czech Republic), Hassan Helmy (Egypt)

This symposium welcomes contributions that enhance our understanding of metal solubility, speciation, and transport in geologically-relevant fluids (aqueous or non-aqueous) and melts (silicate, sulfide, carbonate) in ore-forming environments.

28.6 Metamorphism and Ore Remobilization
Xiaochun Li lixc1986@hku.hk (Hong Kong, China), Richen Zhong (China)

Various mechanisms may contribute to metamorphic remobilization of ore deposits. These include (i) mechanical (stress-induced), hydrothermal (fluid-assisted), and (ii) sulfide partial melting (melt-driven). Mechanical remobilization modifies morphology of the ore body, apart from significant recrystallization of ore and gangue minerals. Hydrothermal remobilization accounts for dissolution and re-precipitation of ore-bearing phases. Sulfide partial melting can take place from upper-green schist to granulite facies. Studies have demonstrated that prograde partial melting of sulfides and consequent crystallization is a significant ore remobilization mechanism, which leads to enrichment of strategic elements in the remobilized ore, which were initially disseminated. With the improved chemical/isotopic analytical techniques, it is possible to characterize the metamorphic fluids and the nature of sulfide partial melting during remobilization. This symposium invites contributions on various such aspects of Metamorphism and ore remobilization.

29.1 Uranium Mineral Systems: Genetic Models and New Understandings of Uranium Deposits
Susan M Hall susanhall@usgs.gov (USA)

The dramatic increase in cost of Uranium since 2005 has resulted in discovery of new occurrences and interest in uranium mineral system. Mineralogy and geochemical characteristics of these new occurrences have been studied extensively. Now the time has come when information generated by the understanding of such development should be discussed across the globe. Recently IAEA has published review on existing uranium deposits classification and proposed a classification scheme based on genetic understanding. This symposium therefore invites papers on
1: Uranium deposit types, genetic models and its understanding.
2: Mineralisation, geochemistry, mineralogy and classification of uranium deposits

29.2 Advances in Uranium Exploration and Exploitation
Michel Cuney michel.cuney@univ-lorraine.fr (France)

Economic uranium deposits resulted from original inhomogeneity’s of uranium distribution in the Earth’s crust that commonly persisted through long periods of time, and through a combination of orogenic, metamorphic, and sedimentary processes produced rocks with enriched uranium contents. The initial enriched uranium domain was successively remobilized and concentrated into new enrichments of one or more magnitudes above normal background forming uranium ore deposits. This symposium aims to discuss nature, origin, evolution, and distribution of U provinces. The modelling and exploitation related development will also be discussed.

29.3 Unconventional Uranium Resources: A Global Perspective
Patrice Bruneton p.bruneton@orange.fr (France)

This symposium intends to discuss unconventional uranium resources as recoverable resources associated with phosphate rocks, non-ferrous ores, carbonatite, black shale and lignite. They correspond to low to very low grade, generally very large geological resources where uranium can only be extracted as a co- or by-product. Mostly it is not possible with existing technologies to recover them rather they are the future resources due to development of technological advancement. Economics play a vital role in this process. The unconventional resources are associated with intrusive plutonic, polymetallic iron oxide– copper–gold breccia complexes (IOCG-U), volcanic-related, Au-rich palaeo-quartz-pebble conglomerate, placers, lignite–coal, phosphorite and black shale [6]. The largest unconventional resources are in seawater, with resources estimated at 4 billion t at an average ‘grade’ of 3.3 ppb (3.3 mg/m3).

29.4 Thorium: Future Energy Source Exploration, Resources and Technology
Harikrishnan Tulsidas harikrishnan.tulsidas@un.org (Switzerland)

He has wide experience in exploration, resource evaluation, development, process innovation, and international policy formulation. He currently works as Economic Affairs Officer in the United Nations Economic Commission for Europe (UNECE) and leads the work on development of global standards for sustainable management of critical raw materials.

The increased demand of carbon-free energy, requires the sustainable use of fuel resources such as uranium and thorium. Uranium though is the main-stay of the present generation of Nuclear Power Plants, with the anticipated steep growth in nuclear energy it will be necessary to introduce thorium too as a fuel. Thorium fuel cycle offers several potential advantages over a uranium fuel cycle, including greater abundance, superior physical and nuclear properties of fuel, enhanced proliferation resistance, and reduced plutonium and actinide production. Technically thorium has been well established and it behaves remarkably well in Light Water Reactors, High Temperature Reactors and Liquid Fluoride Thorium Reactors. Recognizing the potential contribution of thorium fuel cycle in nuclear energy, renewed R&D efforts is seen in much country. Geologically thorium deposits are found in alkaline complexes, pegmatites, carbonatites and heavy mineral sands with wide geographic distribution. Major resources of thorium are seen in Australia, Brazil, Canada, India, Norway, South Africa and USA. Thorium exploration is presently continuing in some countries such as India and USA. The present production of thorium is mainly as a by-product of processing of heavy mineral sand deposits for titanium, zirconium and tin.
The symposium is targeted to discuss latest information on the latest developments in geology, mineralogy, exploration, resources, production, ore processing, environmental studies, safety and social licensing aspects.

Keywords: Thorium, resources, technology, energy generation

29.5 Uranium Resources and the Fuel Cycle for the 21st Century
Christophe Xerri c.xerri@iaea.org (Austria), Harikrishnan Tulsidas (Switzerland)

Christophe Xerri is a leading world expert in nuclear fuel cycle. He has a long experience in the French nuclear company, Areva. He had worked as Counsellor (Nuclear) to the Ambassador of France in Japan before joining IAEA as the Director of Fuel Cycle and Waste Technology Division.

Harikrishnan Tulsidas is a professional geologist with over 30 years of experience in management and development of uranium and energy resources. He has wide experience in exploration, resource evaluation, development, process innovation, and international policy formulation. He currently works as Economic Affairs Officer in the United Nations Economic Commission for Europe (UNECE) and leads the work on development of global standards for sustainable management of energy and raw materials

This symposium is planned to discuss sustainable development in the coming decade will be crucial for all countries, setting the stage for the rest of the 21st century. The 2030 Agenda for Sustainable Development set ambitious goals to ensure prosperity and security for the entire planet. All the 17 goals outlined in 2030 Agenda will require massive energy and material flows. Moreover, the goals encompass low-carbon foot-print and minimum impact to the environment during the production of energy and materials.
Nuclear energy will have a significant role in the low-carbon energy mix that will power the world on a sustainable path. Most of the energy scenarios for maintaining the 2°C increase above the pre-industrial levels in global temperature require a high share of nuclear energy. Large-scale utilization of nuclear power is foreseen in many countries, especially in the most populous India and China. Under the IAEA high case scenario nuclear power would see a 3-fold increase by 2050.
Uranium has to be seen as a low carbon fuel that can help realize many of the Sustainable Development Goals and climate commitments. Uranium resources to power the fleet of reactors are not only required in a timely manner but also need to be produced sustainably. The comprehensive recovery of uranium from unconventional resources including from wastes and tailings will be significant in future. In addition to new technologies for obtaining more uranium, the nuclear energy industry will have to examine practices in resource management including safe handling of mine tailings and long-term storage of spent fuel to ensure sustainability.

Chandan Chakraborty, Prof. Chandan Chakraborty has done extensive research on palaeogeography and tectonics of sedimentary basins including Gondwana basins of India, Deformation behaviour of different types of Rock Systems etc.

Anjan Rai Choudhuri, Dr. Anjan Rai Chaudhuri has more than 15 years’ experience in coal exploration in different Gondwana basins of India. His area of interest involves sedimentology, structural geology, basin modelling.

Goutam Mukherji, Gautam Mukherjee is an expert in exploration planning, characterization and assessment of resources with more than 30 years’ experience in the field of coal/lignite exploration.

Coal is the second most important energy source, covering 30% of global primary energy consumption and is the leading energy source in power generation accounting 40% of globally generated power. Many of the developing countries, including India, is well endowed with coal resources and these countries are increasingly satisfying their growing energy demands with cheap coal in order to sustain their economic growth. Hence, despite its insidious influence on the climate and health, coal is unlikely to be replaced in near future as the major player in energy scenario in most of the countries.
Coal deposits of the world formed from plants that grew in and adjacent to swamps, mostly, in warm, humid regions. Under certain conditions this organic material continued to accumulate and was later converted into coal. There are distinct time spans during which most of the world coal deposits were formed which represent periods during which several favourable biological and physical processes occurred simultaneously. Study on paleogeography, tectonic framework, paleobotany, palaeoclimate and sedimentary history helps to understand the depositional environment that favoured coal formation.
This symposium will cater to all researchers related to the geological aspects, exploration and economics of coal deposits.

29.7 Coal: Characterization, Beneficiation and Utilization
Uttam Kumar Bhui Uttam.bhui@spt.pdpu.ac.in (India), V. A. Mendhe (India), Naeem Ahmad (India), Sudip Bhattacharyya (India)

Dr. Bhui’s present research activities are related to molecular level characterization of crude oil, organic matter rich shale, coal, for development of new methods/techniques for the future use in much cleaner, greener and economic way.

Dr. V. A. Mendhe has completed about 122 R&D projects and has 140 research publications. He is member of editorial boards of several international journals and a number of professional national and international societies.

Naeem Ahmad is an expert in exploration planning, modeling, characterization and assessment of resources with more than 40-year experience in the field of coal/lignite exploration and in-depth knowledge of almost all Indian coalfields.

Dr. Sudip Bhattacharya has more than 20 years’ of experience in coal exploration.

Coal is likely to continue to be the major source of energy for many years to come but the manner in which coal is used must, and will, change. Advances in analytical techniques, modeling software with high power of computation system have resulted in improved partial representation of coal structure. but complete grasp on chemical constituents, their structure and their binding mechanism for the solid fuel is remain elusive.
Coal, with high carbon content than other fossil fuels, produces maximum CO2 when combusted. In addition, coal also contains a host of elements including Sulphur, nitrogen, mercury and heavy metals which pollute the environment when coal is mined or burnt.
Coal research has evolved to reduce all the disadvantages it has in conventional method. Today coal is seen in various ways of utilization with the help of many new and evolving techniques of characterization in molecular level. We have technologies in hand that will allow coal to be used in a more environmentally friendly manner. It seems that opportunities still exist for developing new processes and technologies, which need to be more economic, effective and efficient that may be unconventional in nature. This symposium therefore invites papers on Coal petrography, coal chemistry and beneficiation.

Dr. Liu has 25+ years of experiences in reservoir characterisation, geofluid and petroleum system modelling. He is an associate editor of AJES & JAES, and active members of AAPG, AGU, IAS and SPE.
Mr. Barua has 30+ years of experiences in petroleum system modelling and sequence stratigraphy.
Mr. Vasudevan has 33+ years of experiences in basin evaluation, sequence stratigraphy and reservoir characterization for hydrocarbons.
The Petroleum System is a unifying concept that encompasses all disparate elements (source, reservoir, seal, and overburden rock) and processes (trap formation, generation-migration-accumulation) of petroleum geology. This also includes genetically related petroleum that originates from one pod of active source rock and occurs in shows or seeps. These essential elements and processes must be correctly placed in time and space so that organic matter included in a source rock can be converted into a petroleum accumulation. The petroleum system generally occurs in sedimentary basins up to 7000 m depth. A significant breakthrough has been made in China and elsewhere in exploring deeply buried (more than 7000 m) reservoir plays. Advancement has also been made in accumulation mechanisms in micro-nano pores, under the influence of organic-inorganic interaction. This symposium invites contributions on Shallow to Deep to Ultra-Deep Petroleum Systems. Papers on petroleum exploration, basin analysis, play fairway analysis, petroleum systems, resource assessment, fracture basement, role of geophysics and petrophysics, based on geoscientific studies are invited.

Sh. Lochan, a Coal Geologist having 30+ years of experiences, worked on development and management of coal based unconventional energy resources, and implemented projects with CSIRO, Australia.

Shale gas, a natural gas trapped within shales (fine-grained sedimentary rocks), has captured the spotlight after successful production in USA by hydraulic fracturing and horizontal drilling and now well accepted in China and Poland as well. The interests have spread to tap this natural gas in Canada, Australia, and many European, African and Asia-Pacific countries including India because of its considerable reserve and less emission of greenhouse gas compared to other fossil fuels. Papers on exploration and exploitation strategies of shale gas are invited into this symposium.
CBM (Coal Bed Methane) refers to gas that is generated during coalification and stored within coal, as being a reservoir. This symposium expects papers on pressure, temperature and structural controls on the accumulation of CBM in coal; importance of hydrodynamic sealing in CBM accumulation and preservation; numerical modelling and reservoir simulations to understand the impact of stress dependent anisotropic coal permeability on well design; and gas content, permeability and depth & thickness of coal seam for economic production and resource evaluation in distressed condition also to optimize its utilization to reduce GHG impact under Global Methane Initiatives with suitable technology.

Dr. Nummedal is also the director of the Carbon Management Centre at CSM. He is a Research Professor and has vast experiences in Geology, Geophysical imaging and Petroleum Engineering.

Consumption of fossil fuels increases CO2 concentration in atmosphere that leads to global warming. As a step forward in reducing the global temperature by ~20o C, as suggested by the Inter-Governmental Panel on Climate Change (IPCC), the carbon capture, utilization and storage (CCUS) experiment is one of the best alternatives for reducing the carbon footprints. Saline aquifers, depleted oil and gas fields, basalt formations, deep coal seams and deep water shallow marine sediments are potential sites for CO2 storage. These procedures, though, have its own drawbacks of limited storage capacity. Connectivity between capture and transportation to storage sites and the geological leakage of stored CO2 are cost intensive. The CCUS initiatives in developing economies are still in initial stage. This symposium invites papers covering several aspects of CCUS experiments.

Energy security and environmental integrity have long been two major global issues of importance. Sufficient energy is essential for global economic growth along with minimal environmental impact. Facing the current global energy and environmental landscapes, it is timely to have a symposium session devoted to recent advances in tectonics and sedimentary basins that could help successful exploration for and effective development of oil and gas in a cost effective and environmentally sound manner. A petroleum system is spatially and temporally associated with a particular basinal setting, such as rift, sag, passive margin, and foreland, at a specific episode from the opening to the closing of greater ocean basins. Thus, not only do sedimentary basins provide the sources, reservoirs, and traps for oil and gas, but also they offer critical information regarding basin prototypes, which in turn can be instrumental in recovering the dynamic interplay among plate tectonics, syntectonic sedimentation, and hydrocarbon accumulation. The scope of this symposium session is intended to cover any aspects of sedimentary basins, including current case studies, innovative concepts and methodologies, with special reference to important sedimentary basins around the world at varying scales and from different perspectives.

Plate Tectonics refers to the geological processes that physically construct and shape the surface of planet Earth and is also capable of producing the most violent and destructive physical events (earthquake, volcanism, tsunami, landslide, etc.) which may occur in inter-plate or intra-plate regions with different kinematics. Geohazards due to these physical events provide a growing global challenge to the professional community. This symposium explores the implications of primary research, secondary consequences and tertiary conclusions related to all types of natural hazards in relation to crustal dynamics. The issues include identification and characterisation of seismogenic and non-seismogenic faults at different tectonic settings under contemporary tectonic stress environment, recurrence intervals for faults that are capable of generating earthquakes, temporal and spatial clustering of earthquakes, event chronologies, delineation of high strain zones and its relation with present tectonic stress, governing factors and comprehensive modelling on real time and delayed earthquake triggered landslide, critical factors for tsunami generation and its effect on wave probation-inundation, prediction of volcanism through volcanic seismicity, ground deformation, gas emission etc. at inter-plate regions and hotspot related intra-plate seismicity. Contributors are encouraged to present work that shows new discoveries, methods, practices and scientific results which can be successfully applied globally to benefit society in general as they are linked to our efforts to improve understanding of, resilience to and management of such natural threats.

One of the possible sessions under this symposium: Paleoseismology of the Frontal Himalayan Fold and Thrust Belt and Earthquake Hazards (proposed by R. Jayangonda Perumal, Tina M. Niemi, Javed Malik)

Several paleoseismological studies have been conducted during the last decade in an attempt to determine the timing, magnitude, rupture extent, return period, and faulting mechanics associated with the occurrence of large surface rupturing earthquakes along the ~2500 km long Himalayan Frontal Thrust Fault (HFT) or Main Frontal Thrust Fault (MFT). However, divergent viewpoints of different research groups have given rise to uncertainties surrounding the temporal constraint of paleo-earthquakes in the Himalaya. Moreover, the possible overestimation of the age of past ruptures, due to errors associated with reworked detrital charcoal samples and/or the inherited age of those samples, causes ambiguity surrounding the use of radiocarbon age results to precisely date paleo-earthquakes in the Himalaya. The session intends to address the above issues, and to discuss the geological crustal shortening rate at different time frames along the Himalayan frontal fold and thrust belt to improve the existing Himalayan earthquake model.

Niroj K. Sarkar, a senior research scientist with Geological Survey of India having long experience in landslide research in the Himalayas.

Landslides hazard, in many areas of the world cause significant societal and economic damage. Due to their large natural variability, and the inherent difficulties to recognize and map landslides where and when they occur, landslides and their damaging effects remain difficult to predict. This limits the ability to mitigate landslide risk, and to reduce their societal, economic and environmental consequences. This symposium will provide an opportunity to present and discuss new results in one or more of the following themes: (i) detection and mapping of landslides, including subaqueous landslides, from the local to the global scale, (ii) landslide initiation and propagation mechanisms, and their physical and numerical modelling, (iii) landslide and slope monitoring strategies and methods, with emphasis on new or emerging technologies, (iv) statistical and physically-based modelling of landslide processes, and model validation methods, (v) temporal and geographical landslide forecasting models and methods, at all scales, (vi) physical (e.g., geophysical, climate, environmental) and human drivers of landslides, and their expected impacts given their projected geographical and temporal variations, (vii) landslide vulnerability estimation, economic impact and risk assessment, mitigation methods.

This symposium aims to address complex hazard interactions that may affect large areas, spanning across different countries. These disasters may have triggers that are remote from the affected areas, and require exchange of information between different regions or countries. The symposium will address four types of transboundary disasters and hazard interactions:

• There could be transboundary hazards related to earthquakes: co-seismic and post-seismic events in mountains, such as landslides, debris flows, landslide lake outburst flows (LLOF), Glacial lake outburst flows (GLOF). • Related to complex interactions related to marine hazards (tsunami’s) and their triggers (earthquakes, volcanic eruptions, large submarine landslides, meteorite impacts). • Transboundary disasters can also have atmospheric origin, related to dispersion of volcanic ash clouds, smoke from major forest fires, dust storms etc. • Transboundary disasters having origin in large extreme meteorological events, such as tropical storms, cyclones, monsoon, and their associated hydro-meteorological hazards, such as large flooding events, landslides, debris flows, wind damage etc.

The symposium would like to bring scientists together that address the complex interaction between different hazards and focus on methods for spatial and temporal prediction and modelling.

Geohazards pose an increasing threat to society and therefore, it is necessary to develop models and methodologies for better understanding societal impacts in terms of life loss and economic setback in developmental perspectives. Predicting or developing well-tuned early warning for events like landslides (mass movements), earthquake, avalanche, flood, Volcanic mud flows (Lahars), sinkholes, etc. has been a hot topic for research and governance issues. At some specific areas in the globe, Earthquake induced submarine landslides cause Tsunami and cascading effect of the same to coastal habitats are woefully noted. While early warning for Tsunami is available, the same for earthquake is in nascent stage. The early warning systems incorporate the monitoring of physical processes and mechanisms for measuring, modelling and predicting geohazards. Developing early warning systems also requires setting criteria for parameters to be monitored and threshold values; equipment and systems; coordinating satellite radar data with local monitoring stations; planning monitoring programs for high-risk areas; and developing computer-aided decision-making tools with e.g. mobile data mapping and retrieval, and information management using geographical information technology (GIT), Remote sensing (RS), IT Enabled services, Artificial Intelligence (AI), Internet of Things (IoT) and 3D modelling. It is also important to prepare user-guidelines for data review, alarm facility and follow-up, telemetry/VSAT/WiFi links, and actions to be taken in the event of threshold values being exceeded andin-place automated warning signal dissemination procedure for individual and administrative users is also required, followed by safety and action plans. This symposium invites contribution on various such aspects of Monitoring, predictability and early warning of geohazards.

As per United Nations reports, 55% of the present global population resides in urban areas and this percentage is expected to rise to 68% by 2050; an addition of 2.5 billion people in the urban areas compared to present status. While the urban population in 1950 was 571 million, by 2050 it is going to witness a steep rise to 4.2 billion.
This unprecedented growth in urban areas is to a great extent, unplanned, without taking into account proper land use planning, adoption to existing building codes and regulations which are major contributors to the layers of vulnerabilities of urban areas. While many of the existing/ upcoming urban agglomerates are located in identified hazard zones like seismic zones, landslide prone areas, others are located in coastal areas are exposed to threats arising from sea level changes. Economic status of the urban population adds to the risk as the economically marginalized groups are pushed to the fringe and more hazardous areas. New aspects of urban hazards are appearing in the past decades in form of increasing trends of urban floods, stampede, road/rail accidents, industrial disasters, coastal degradation.
The proposed symposia ‘Urbanization and Geohazards’ aims to provide a platform for the global geoscientific community to deliberate on and share innovative research experiences in the Disaster Risk Reduction (DRR) practices in urban areas. Contributors are encouraged to present work on new tools for risk assessment and mitigation; role of geosciences in mainstreaming DRR practices; improving present DRR policies; resource management; urban early warning; increasing community participation; use of big data in urban DRR etc. Interested professionals are encouraged to also contribute through more innovative ideas.

31.10 Global Disaster Risk Reduction Policies: Status, Scope and Future Perspectives
Mriganka Ghatak mghatak.sdmc@gmail.com (India), Shahnaz Huq Hussain (Bangladesh)

The areas of expertise of Mriganka Ghatak include Quaternary Geology, Earthquake Geology with special reference to Active Fault Studies, Tectonic Geomorphology, Paleoclimate studies. He has extensive experience of working with the major regional and global stakeholders in the field of Disaster Management. He has played an active role in DRR in SAARC region and worked in close collaboration with global DRR stakeholders.

Shahnaz Huq Hussain is a well-established name in the field of Geography and Environment. She has taught and researched in this field for 40 years with special emphasis on Gender, Disaster and Climate Change. Conducted three SAARC trainings on Climate change, River Erosion & embankment safety management in South Asia, organized jointly by the SAARC Disaster Management Centre, New Delhi, India and the University of Dhaka, Bangladesh, during 2009, 2012 & 2014.

One of the prime requirements of Disaster Risk Reduction (DRR) in global, regional, national and local level is robust policies, their implementation and revision of the existing policies as necessary. Giving due recognition to DRR and developing risk resilience down to community level, there have been several policies/ frameworks from time to time. One of the earlier global initiatives for risk reduction has been declaration of 1990-1999 as the International Decade for Natural Disaster Reduction (IDNDR). Within IDNDR framework, Yokohama Strategy (1994) was one of the first adoptions of all-encompassing plan of action for rest of the decade. Subsequent Hyogo Framework for Action (HFA, 2000-2015) had set time bound strategic goals, priorities and expected outcomes. HFA had an in-built system of monitoring progress and the process of the next cycle of global DRR was set in motion by 2012 through consultations and inter-governmental negotiations. The Sendai Framework for Disaster Risk Reduction has been adopted by the states for the period 2015-2030. Drawing from the experience of the previous exercises, the Sendai Framework has laid strong emphasis on disaster risk management against mere disaster management.

The DRR policies/ interventions have also been on regional scale viz. ASEAN Agreement on Disaster Management and Emergency Response (AADMER) and SAARC Agreement on Rapid Response to Natural Disasters (SRRND). However, such adopted commitments have seen failures- SRRND, even after ratification by the members, is yet to be set in operation.
In light of the above, under the aegis of 36th International Geological Congress (IGC), the professional and stakeholders of DRR are invited to deliberate on the issues related to status, scope and future initiatives in DRR. This symposium intends to deliberate on good practices, success stories, role of SDG/MDGs, potential of assessment reports, areas of future concern for DRR in global to community level, learning experiences from past policies that can still be adopted. This symposium aspires to be a trendsetter, inviting all DRR stakeholder bodies, paving way for future participation of DRR communities in IGC.

In 2011 the World’s population exceeded 7 billion people, twice as many as in 1967. While the rate of increase is declining, the population is still expected to reach 9.7 billion by 2050. Consequently, human impacts on the Earth’s physical, chemical and biological systems are also growing dramatically. It has been estimated that deliberate global movement of rock and soil compounds, including toxic constituents, by human activity now exceeds that of transport by the World’s oceans by a factor of three and is likely to increase. Human activities have similarly affected the global nitrogen and carbon cycles. These enormous geological and geomorphological transformations are driven by population growth, urbanization and global industrialization. The release of technically enhanced geogenic contaminants (TECGs) from mining and hydrocarbon (especially non-conventional hydrocarbon) exploitation is also a growing issue. Population pressures have placed people at increasing risk to geological hazards or in closer proximity to past damage. The demand for natural resources is increasing with consequent environmental impacts. There are also important archaeological resources in anthropogenic deposits that can be threatened by insensitive and unsustainable development.
People are now a major factor in our “Dynamic Planet” and will increasingly be so. It is important to consider the future social economic and environmental changes (including climate change) that will exacerbate problems associated with anthropogenic deposits, including those containing geogenic contaminants.
There are many existing standards, specifications and protocols for dealing with technical and administrative issues in many parts of the World. There is a need to increase awareness of the best of these but also to make improvements to secure better protection of environmental and human health and protection of cultural and natural resources while exploiting essential resources. This symposium intends to discuss all these issues.

Geochemical investigations help us in providing societal and economic needs, in the exploration of mineral deposits, sustainable mining, metallurgy of ores and solving related environmental issues. Geochemistry of rock weathering, soil formation and nutrient provisioning, heavy metal pollution, waste disposal, carbon sequestration and intervention of geomicrobiology are the key aspects that deal future sustainability of soil fertility. Identification of aerosol source, understanding their dynamics and air pollution including smog are burning issues where geochemistry provides the solutions. Forensic and medical geology are other facets available for geochemical investigations and providing solutions. An important point for all these geochemical investigations is to mark the baseline level of elements, which help to recognize and understand the deviations from the natural background level. Therefore, developing systematic geochemical maps is essential for the basis for monitoring changes in the levels of chemical elements at the earth’s surface. Geochemical investigations of exposed rocks, regolith, soil horizons, sediments, groundwater, and streams not only help to develop geochemical maps but also in identifying potential mineral resources, understanding surface earth processes and other geological investigations. This symposium invites abstracts on uncontaminated surface earth and atmospheric geochemistry, geochemistry of degraded systems, biogeochemical facets of microbiology, forensic and medical geology.

32.3 Palaeosols and Palaeoweathering Profiles: Indicators of Palaeoclimates and Palaeoenvironments

In unravelling the temporal and spatial characteristics of past climatic and environmental changes, the ancient stratigraphic records have been largely used. Although the climatically driven changes can be studied in detail from marine records, impacts on terrestrial climates during the same periods are poorly known. Hence there is an urgent need to improve our understanding about the mechanisms that influence geological data preservation in various terrestrial proxies which can be extrapolated to today’s fragile global environmental conditions. Continental environmental archives are often highly temporally resolved and may provide more direct information about atmospheric processes than the marine archives and hence can be effectively used in analyzing the mechanisms behind the abrupt changes in the geologic past by integrating the global palaeoclimate data. In the recent past proxy paleoclimate analysis by using geochemical, mineralogical, sedimentological, palaeontological etc. data have been successful in various terrestrial archives like palaeosols, lake and cave sediments, loess, travertines, evaporates etc. Inter-comparisons of proxy data-climate models at regional and global scales are most necessary which combine inorganic, biological and biogeochemical processes acting within the weathering regimes. The aim of this symposia aims at discussing research approaches and results on the interdisciplinary palaeoclimatic studies of the palaeosols and palaeoweathering profiles, involving various proxies such as geochemistry, environmental magnetism, fossil assemblages, mineralogy, clay mineralogy and micro-morphology of the fossil soils etc. This will help in increasing our knowledge of the least studied areas by developing proxies which are sensitive to different aspects of climate and environmental change like Mean Annual Temperature, Mean Annual precipitation, Biological activity, Geochemical environment etc.

Water scarcity and misuse is posing a serious and growing threat to sustainable development and protection of the environment. Human health and welfare, food security, industrial development and the ecosystems on which they depend, are all at risk, unless water resources are managed more effectively in the present decade and beyond than they have been in the past. As countries continue to undergo dramatic shifts caused by climate change, a growing economy and population, competing demands for water coming from households, industry, and agriculture have wide-ranging implications for the country's future.
More importantly water scarcity risks holding back hard earned development and economic growth. Part of the solution can be found in more effective management of water resources and use of innovative technologies. New technologies and innovation exist but they rarely reach the developing countries like India. Techno-economic fixes do not address the underlying “zero-sum game” nature of water resource use. Ultimately, the water management problem is that of allocating the water available each year among users — both people and the ecosystem.
This symposium intends to discuss comprehensive water budgeting, simultaneously in each watershed and the river basin as a whole. Water budgets for the river basin will inform communities how much must be left for downstream users, ensuring that water resources are allocated between communities fairly and transparently.

32.5 Urban Geosciences
Daniel Schertzer Daniel.Schertzer@enpc.fr (France), Klaus Fraedrich (Germany), Stefano Tinti (Italy)

Daniel Schertzer, Dr. Professor and Director of the Chair “Hydrology for Resilient Cities” at Ecole des Ponts ParisTech. AGU Lorenz lecturer and Fellow, EGU Richardson medalist, Paris City Silver medal.

Several recent disasters, in particular in Asia, recall us once again how vulnerable to extreme hazards are our urban systems. Conversely these systems play more and more a key role in climate change, e.g.: 80% of GGH production and about the same percentage of the energy production, the total growth of the world population expected in cities (by 2050, 80% and 60% of for developed and respectively emerging countries). Furthermore, most assets are already highly concentrated there and are facing a wide variety of risks, especially geophysical hazards.
Fortunately, there has been an impressive series of international agreements that call for qualitative improvements of urban systems and their interactions with their environment: The Sendai Framework for Disaster Risk Reduction 2015 – 2030, UN 2030 Agenda for Sustainable Development, COP21 “Paris Agreement”, UN-Habitat City Resilience Profiling Programme (CRPP) and the Urban Agenda for the EU (“Amsterdam Pact”). All these agreements put a strong emphasis on the question of urban resilience.
There has been also the development of large networks of cities to exchange best practices with respect to the aforementioned goals, e.g., 100 Resilient Cities (100RC), ICLEI, Local Governments for Sustainability and C40 Cities Climate Leadership Group (C40).
Overall, the present challenge is s to shift from a short-term mismanagement of resources and risks to a wise monitoring of the environment, to develop holistic responses to both ongoing geophysical changes and urbanization processes and to increase urban resilience to geophysical extremes, water and climate change.
This Symposium will be focused on this challenge, in particular on the necessary involvement of geoscientist and geophysical societies.
This proposal of Symposium will be co-sponsored by EGU

36.1 Polymetallic Nodules: Geological Characteristics and Resource Potential
Abhishek Saha asaha@nio.org (India), Kali Sanjay (India), Thomas Kuhn (Germany)

Dr. Saha is a geologist having more than 10 years of experience handling petrological and geochemical data of diverse tectonic settings; currently heads the exploratory program for PMN (Survey & Exploration) in India at CSIR-NIO

Dr. Sanjay is a metallurgical engineer having about 25 years of experience on processing of wide variety of ores. At present he heads the exploratory programme for PMN (Metallurgy) in India at IMMT.

Dr. Khun is a marine geologist having more than 20 years’ experience on working in different marine resources including manganese nodules; hydrothermal deposits and also in mantle geochemistry.

Polymetallic nodules are rounded accretions of manganese and iron hydroxides that cover vast areas of the seafloor, but are most abundant on abyssal plains at water depths of 4000-6500 metres. The composition of nodules varies, but in addition to manganese and iron, they can contain nickel, copper and cobalt in commercially attractive concentrations as well as traces of other valuable metals such as molybdenum, zirconium and REEs. The essential conditions to form the nodules are (i) low sedimentation rate (ii) availability of nucleus around which accretion of oxides takes place (iii) oxidising environment and (iv) bottom currents of low velocity. The nodules are formed by precipitation from two sources such as (i) precipitation of colloidal particles directly from cold ambient seawater and accretion around a nucleus on soft sediment substrate forming hydrogenetic nodules and (ii) precipitation of metal ions either within the soft sediment or at the sediment-water interace from sub-oxic sediment pore waters where seawater is modified by chemical reactions within the sediment. The nodules of greatest commercial interest occur in the Clarion-Clipperton Zone in the equatorial Pacific Ocean (CCZ) and in the Central Indian Ocean Basin (CIOB). The concept of polymetallic nodules as a serious commercial prospect emerged in the 1960's and 70's, leading to a rush to develop the technology to extract them. Pursuant to the establishment of the International Seabed Authority in 1994 under the 1982 United Nations Convention on the Law of the Sea to organize and regulate mining and related activities in the international seabed beyond national jurisdiction, the Authority has entered into 15-year contracts for exploration of nodules in specific parts of the deep oceanin the CCZ and CIOB. Under the Contract, in addition to carrying out survey and exploratory activities within the contract area, the contracting agencies are also required to undertake Environmental Impact Assessment and to develop suitable exploratory, mining and processing technologies. Abstracts are invited in this symposia on geological and geochemical characteristics of the nodules in different areas, the effect of geological factors such as the depositional environment, sediment characteristics, hydrography etc, on nodule abundance, its composition and processing options.

Dr. Kamesh Raju is a reputed marine geophysicist who has contributed significantly to India’s deep seabed mineral exploration program as well to the studies of arc-backarc systems

Dr. John Kurian is a leading marine geophysicist with a proven track record in the field of seabed hydrothermal mineral exploration and mapping.

Dr. Jerome Dyment is a renowned marine geophysicist, head of the Marine Geoscience Team at the Institut de Physique du Globe de Paris, Chair of the International InterRidge Program and Chair of one of the geology Science Theme of teh International Indian Ocean Expedition

Modern seafloor hydrothermal systems, with their black/ white smokers issuing hot metal rich vent fluids from mafic or felsic volcanic rocks can be considered as modern analogs for the formation of volcanic-hosted massive sulphide (VMS) deposits. The discovery of such systems in the deep oceanic realm along the mid-ocean ridges has kindled a lot of interest primarily on account of the high concentration of base metals (Cu and Zn) and many noble metals (Au, Ag, Pd, Pt) in them. Of the more than 400 hydrothermal sites reported along the length of the mid-ocean ridges and arc-backarc systems, about 140 are considered to have economic potential with respect to polymetallic sulphide minerals. Apart from their economic potential, these deep-ocean mineral deposits can be considered as windows into Earth's processes, revealing clues to the evolution of seawater and ancient ore-forming processes.

Pursuant to the establishment of the International Seabed Authority in 1994 under the 1982 United Nations Convention on the Law of the Sea, the Authority has entered into six contracts with different entities for the exploration for polymetallic sulphides in the South West Indian Ridge, Central Indian Ridge and the Mid-Atlantic Ridge. Against this background, this Symposium would solicit abstracts on both modern active hydrothermal systems and relict seabed hydrothermal deposits, focused on the geology, geochemical characteristics including water-column chemistry, host-rock composition, geological models for seafloor hydrothermal systems, exploration strategies for potential sites of hydrothermal multi-metal sulphide mineralization and determination of the resource potential in different environments.

Dr. Iyer’s research interests are petrology, volcanism, coastal geomorphology, mineral resources (deep sea and coastal placers)

Dr. Banakar’s research interests are deep-sea Ferromanganese deposits with special reference to genesis and paleoceanography of seamount cobalt-rich Fe-Mn crusts; and Palaeoclimatology

Dr. James Hein, a Senior Scientist with the USGS, in an internationally-renowned authority on issues concerning mineral resources that occur within the EEZ and areas beyond national jurisdictions.

Cobalt-rich ferromanganese crusts are the authigenic (hydrogenous) colloidal precipitates accreted on exposed hard substrates over the seamounts of the world oceans. Older seamounts normally host thick crusts up to several tens of cm. As these crusts grow at extremely slow rates (few mm/my) they can act as repositories of long-term paleoceanogrphic records. The seamount crusts accreted close to the Oxygen Minimum Zones are expected to be enriched with very high concentration of cobalt up to even 2 % and are termed as Cobalt-Crusts having very high economic value. These crusts often are enriched with Platinum Group Elements, Tellurium and Gold, which add-up to the value of the crust deposits.

Pursuant to the establishment of the International Seabed Authority in 1994 under the 1982 United Nations Convention on the Law of the Sea, the Authority has entered into four contracts with different entities for the exploration of cobalt-rich crusts in the Western Pacific Ocean. The recent preliminary exploration in the Equatorial Indian Ocean has also indicated occurrence of Cobalt-rich crusts in the Afanasiy-Nikitin Seamount cluster.
With this background, it is quite feasible that the seamount cobalt-crusts in addition to their academic interest have economic potential of high value and may act as raw material for several high-tech metals. This symposium would invite abstracts related to formation of the seamount crusts; their scientific and economic importance; advancement in their exploration, mining, and metallurgical challenges and environmental impact on seamount cobalt-crust mining.

36.4 Exploration for Deep-sea Mineral Resources: The Scientific and Technological Challenges
G. A. Ramadass ramadass@niot.res.in (India), John Kurian (India), Georgy Cherkashev (Russia)

Dr. Ramadass has been involved in developing technologies for the exploration and harvesting of ocean resources for the last 24 years and has a number of publications and patents to his credit.

Dr. John Kurian is a leading marine geophysicist in the country with a proven track record in the field of seabed hydrothermal mineral exploration and mapping.

Prof. Cherkashev is an internationally-renowned geoscientist in the field of prospecting and exploration for polymetallic nodules and sulphides in the Pacific, Atlantic and Indian Oceans.

The exploration for deep-sea minerals and mineral deposits such as polymetallic nodules, polymetallic sulphides and cobalt-rich crusts in the seabed area presents several challenges in terms of the water depths at which they occur, their sporadic and restricted nature of occurrence, and the availability of suitable technologies needed for locating these resources. While the nodules occur on the sea-bottom sediments, generally half-buried and at water depths exceeding 4000 m, massive sulphides form discrete compact mounds along the plate boundaries over very restricted aerial extent, and the thin ferromanganese crusts are adhered to large areas of hard rock substrate. Such wide variations in the nature of the occurrence make their retrieval difficult. Furthermore, as regards the polymetallic sulphides and the crusts, the present technologies also impose limitations on drilling to adequately determine grade and tonnage. This Symposium proposes to invite papers focused on: the scientific and technological challenges in prospecting for these deep-sea mineral resources, and the developments in technology for exploring these resources.

Dr. Rahul Sharma is the editor of the book on ‘Deep-sea mining’ published by Springer in 2017. He has led the project on EIA of deep-sea mining in Indian Ocean. His fields of interest are seafloor environment associated with deep-sea minerals and has authored several papers on potential impacts of deep-sea mining.

Dr. Baban Ingole has been associated with the EIA project on deep-sea mining as a marine biologist and is n expert in marine biodiversity and ecology. He has authored several papers on deep-sea faunal assemblages and potential impact of deep-sea fauna.

Dr. Yoshihisa Shirayama has served as a professor of Seto Marine Biological Laboratory before joining the current position at JAMSTEC. His fields of interest have been marine biodiversity, taxonomy and ecology of deep-sea meiobenthos and the impact of ocean acidification upon it.

Dr. Teresa Radziejewska, is Professor of Marine biology at the Natural Sciences Education and Research Centre, University of Szczecin, Poland and has extensively worked on deep-sea fauna and the environmental impacts of deep-sea mining. She is a member of international research groups with several publications.

Mining of deep-sea minerals, many of which occur in the international waters, has attracted significant attention due to discovery of large volumes on the seafloor and growth in global demands for strategic metals such as copper, nickel, cobalt and rare earths. This has led to several entities registering claims for obtaining exclusive rights over large tracts of the seafloor under UN Law of the Sea and also developing technologies for their exploitation. On the other hand, environmental groups have been flagging concerns over the possible environmental impacts on the hitherto untouched marine ecosystems that house unique biodiversity. This symposium will address environmental issues in relation to deep-sea mining; look at the potential impacts on marine ecosystem as well as the mechanisms being put in place for mitigation and conservation.

36.6 Deep Sea Mining Within and Beyond National Jurisdictions: Technological Developments and Regulatory Frameworks
M. A. Atmanand atma@niot.res.in (India), Tetsuro Urabe (Japan), S. Rajan (India)

Dr. Atmanand, an Ocean Engineer by profession has done pioneering work in the area of deep sea technologies in India.

Prof. Urabe is an internationally-recognised figure in the field of seafloor hydrothermal activities both on the mid-ocean ridge and the arc-backarc systems.

As the quest for deep-sea mineral resources is gaining momentum, development of suitable mining technologies catering to their recovery from diverse in situ environmental conditions has become an important aspect of study. Furthermore, because many of these resources occur both in national and international waters, efforts are also on to develop regulations governing their exploitation in a sustainable manner at national and international levels.
This Symposium will thus have a two-fold focus: one, on the prospects and challenges of deep-sea mining of non-living resources; and two, on the legal framework governing deep-sea mineral extraction and exploitation in two different, yet inter-linked, jurisdictional contexts (national and international) in the developing of mining technologies. Papers are proposed to be invited on deep seabed mining technologies and challenges in their development and deployment, standardization of mining methods, mining design, national laws governing deep sea mineral extraction and exploitation, legal framework governing maritime areas of coastal states where mining activities are already on, and the laws governing seabed mining in the “Area” beyond national jurisdictions.

36.7 Extended Continental Shelves under UNCLOS: Sovereign Rights for Exploiting Non-living Resources Beyond 200 Nautical Miles
Bimal N. Patel vc@gnlu.ac.in (India), Rasik Ravindra (India), S. Rajan (India)

Prof. Bimal Patel is a renowned scholar and academician of international law and diplomacy and currently the Director of Gujarat National Law University as well as a member of the 21st Law Commission of India.

Dr. Rasik Ravindra, a renowned polar scientist, former Director of the National Centre for Antarctic and Ocean Research, Goa and former member of the United Nations Commission on the Limits of the Continental Shelf.

Dr. Rajan, a marine geologist, former Director of the National Centre for Antarctic and Ocean Research, Goa, India, and former member of the United Nations Commission on the Limits of the Continental Shelf.

The concept of legal continental shelf as embodied in article 76 of the United Nations Convention on the Law of the Sea (UNCLOS) and its delineation beyond 200 nautical miles feasible in respect of some coastal States is paving the way for additional areas where States can exercise rights of sovereignty over the seabed, sub-seabed and their natural resources. As on date, 70 Coastal States have lodged 80 Submissions with the United Nations Commission on the Limits of the Continental Shelf for extended continental shelves beyond 200 nautical miles (including joint Submissions by one or more countries). These submissions collectively encompass an area of about 30 million km2 of extended shelf (including potential overlapping claims). Considering that about 150 million km2 of seabed area (which corresponds to the global EEZ area) is already under the national jurisdiction of the world’s coastal States, the addition of a possible 30 million km2 would mean that roughly about 50% of the global ocean seabed with its natural resources could come under national jurisdiction. Against this background, this Symposium invites abstracts on the seabed and sub-seabed resources within the “legal” continental shelf of coastal States, the obligations and the liabilities deriving within the framework of UNCLOS for a sustained development of these resources in terms of know-how, preservation, exploration and exploitation, and the challenges in the management and sharing of natural resources in areas of overlapping claims by States with adjacent or opposite coasts.

36.8 Mineral Resources of the Continental Margins, Excluding Hydrocarbons
V. Purnachandra Rao vprao55@gmail.com (India), A. Anil Kumar (India),

Dr. Rao has been working on continental shelf and slope sediments for the past 38 years. He has contributed significantly towards the formation of authigenic/diagenetic minerals, such as phosphorites, dolomites and verdine-glaucony-phosphate facies and distribution of fine-grained detrital minerals on continental margins.

Dr. Anil Kumar is a marine geoscientist who has worked extensively on the formation of lime muds on the continental margins as well as on the rock-magnetic properties of marine sediments.

Near-shore marine mineral resources, especially from the continental margins are an important topic of research. Several investigators have attempted to identify the resource potential of near-shore heavy mineral deposits, control of hydrodynamic conditions on the distribution of detrital minerals, factors favouring the carbonate sediments and lime muds during the late Quaternary, coastal processes such as upwelling on the formation of phosphorites, and verdine-glaucony facies and minerals from the oxygen minimum zone. This symposium will discuss findings on near-shore mineral resources.

37.1 Ecohydrology
Karl Schneider karl.schneider@uni-koeln.de (Germany)

Ecosystem regulates the interaction of radiant energy and mass transfer that is essential in the development of the Critical Zone. It is known that the Critical Zone impacts ecosystems and interaction between the vegetation and water is important to understand this process; this study of interaction between water and ecosystems is central to the Ecohydrology.
The theme of Ecohydrology encompasses all the hydrological processes impacting distribution and function of ecosystems. The scale may vary from interaction at pore level to the vegetation-atmosphere boundary level.
Keywords: Soil moisture, water cycle, climate-soil-vegetation system

37.2 Critical Zone Science in Tropical System
Laurent Ruiz Laurent.Ruiz@inra.fr (France)

High temperatures, large amount of rainfall, and seasonality characterise the Tropical regions. Further areas with tropical climate can be divided in to wet, wet and dry, dry and cool tropics. Due to variation in temperatures, rainfall, and geology, the rate of weathering varies enormously in these areas, as a result soil production in these areas varies widely. It should be noted that large population lives in these regions, hence it is important to understand the Critical Zone processes in these areas.
Keywords: Soil production, weathering, critical zone, tropical climate
37.3 Biogeosciences
Jean Riotte jean.riotte@get.obs-mip.fr (France)

Understanding of the interactions between the four important spheres viz., atmosphere, hydrosphere, lithosphere, and biosphere is central to the theme of Biogeosciences. The interaction between natural ecosystems, physical and chemical enviroment, and humans is very complex and multidirectional, therefore, to comprehend these processes an integrated multidisciplinary approach is required. The biogeosciences studies have potential to enrich Critical Zone understanding; thus, its important to focus not only up on plant and microbial composition or quantification of processes driven by them but also, up on aspects such as microbial responses to environmental stresses that impacts biogeochemistry, depth up to which biological signals could be observed etc.

38.1 Mapping, Investigation, Characterisation and Management of Aquifers
Dipankar Saha dsaha002@yahoo.com (India)

Aquifers store and transmit groundwater. There are different investigation techniques for locating, demarcating and assessing the aquifers. The non-invasive techniques include the hydrogeological, hydro geochemical, geophysical, and interpretation of remotely sensed data etc., while the invasive techniques are drilling and bore well geophysical investigations. Mapping aquifers, characterising its hydraulic properties, groundwater regime behaviour like space-time variation of hydraulic head/heads are of paramount importance in managing this precious groundwater resource. This symposium would deal with different techniques of investigation, their efficacy and case studies in different hydrogeologic framework areas, behaviour of hydraulic regimes in particularly multi-layered aquifer systems, determination and interpretations of aquifer hydraulic parameters, optimum yield, safe yield, controlled groundwater mining in an aquifer. Water well construction and design issues will also be included into this symposium
38.2 Groundwater Chemistry and Contamination
L. Elango elango34@hotmail.com (India)

Groundwater quality is of major concern due to both geogenic and anthropogenic sources of contamination. The depletion of groundwater resources makes it necessary to safeguard the available resources from contamination. Emerging contaminants need to be continuously monitored in groundwater and appropriate water quality standards should be arrived at regular intervals. Hence, recent techniques of water quality assessment, understanding the changes in spatial and temporal groundwater quality, its relation to the aquifer properties including the fracture systems, deep groundwater, interaction between different aquifers, anthropogenic sources etc. will be discussed in this symposium. Not limited to these, all the other aspects related to groundwater quality and environment, geochemical and numerical models will also be addressed.

38.3 Managed Aquifer Recharge and Groundwater Resource Sustainability
R C Jain ratan.jain@gmail.com (India)

Aquifers have become a dependable source of water worldwide. There is an unprecedented increase in extraction of groundwater, both in areas underlying prolific unconsolidated aquifer systems and also in not so potential fractured aquifer systems in consolidated sedimentary and crystalline areas. Over-exploitation of groundwater resources is a common phenomenon now cutting across the basins, countries and continents. One of the main ways to combat over-exploitation is to recharge the aquifers artificially in addition to their natural replenishing capacity through rainfall infiltration. Artificial recharge aims to arrest the overland flow and divert it into the aquifers through some improvised structures. Improvements can be made in the chemical and bacteorological quality of the source water of recharge. This symposium will deal on both the traditional and modern recharge techniques, their efficacy and performance in building up groundwater resource and improvement of water quality.
38.4 Fragile Hydrogeology of Coastal, Island and Other Sensitive Areas
Abhijit Mukherjee amukh2@gmail.com (India)

Major part of the world’s population lives in the coastal areas and they depend to a large extent on groundwater. With increasing demand for freshwater, the groundwater pumping is also increased in these areas. Coastal aquifers are particularly sensitive to changes in groundwater extraction as they are generally connected to the sea and groundwater over-pumping may lead to seawater intrusion. In some other regions of the world, a large amount of groundwater gets discharged into the sea. Thus, the submarine groundwater discharge and seawater intrusion are of international research interest. Characterisation, understanding and predicting the future groundwater level in such regions are also essential for the proper management of these aquifers. All aspects related to coastal aquifer characterisation, interaction between multi-aquifers, complex hard rock aquifers, new techniques of identification of interaction between the sea and aquifers, natural and induced tracers, density dependent modelling tools etc. will be considered under this sub-theme.
38.5 Deeper and Trans-Boundary Aquifers
Sashank Sekhar sashankshekhar@gmail.com (India)

The impact of the increase in groundwater extraction is felt immediately in the decline in hydraulic heads of the aquifers. The declining water levels warrant quest for potential zones at greater depths. In arid and semiarid areas, underlain by both the unconsolidated and consolidated formations, the depths of wells are increasing in a rapid pace in last two decades. In some unconsolidated areas, though potential shallow aquifers are available, the deeper aquifers are exploited for better potable groundwater. In unconsolidated multi-tiered aquifer systems, the groundwater at places occurs under tremendous confined condition at deeper levels, even resulting in auto-flow conditions. The deeper aquifers, need to be investigated for their geometry and hydraulic behaviour, chemical quality and extractable volume of groundwater, as it forms a strategic resource. In many a cases the deeper aquifers form transboundary aquifers between river basins, administrative boundaries and countries. In future, with accentuated crisis of water, trans-groundwater issues can flare up. This sub-theme will deliberate on status of knowledge and new findings on deeper aquifers in different parts of the world, groundwater resource availability, vulnerability, and its value as a strategic resource in the scenario of climate change.
38.6 Impact of Climate Change on Groundwater
Makoto Taniguchi makoto@chikyu.ac.jp (Japan)

Climate change is inevitable and has caused variations in recent climatic conditions such as the global atmospheric temperature, extreme precipitation events, sea level rise and heat waves among other effects. Such changes in climate impacts the extraction of groundwater resources and use of nutrients and other chemicals in agriculture. The Intergovernmental Panel on Climate Change predicts that the impact will also be on groundwater quality through increase in the concentration of nutrients, salts, pesticides and pathogens. Regional and local level estimates of these effects should be studied to understand the likely impacts of climate change in the future, as this will assist in planning adaptation measures. All aspects related to the impact of climate change on groundwater resources will be taken up in this symposia.

The systems approach to understand formation and spatial localization of mineral deposit, termed the mineral systems approach, has been gaining wider acceptance over the past decade. In this approach, mineral deposits are regarded as economically significant concentrations of metal(s) brought about by synergistic interaction of diverse geological subsystems operating on a variety of scales in Earth’s crust to focus substantial mass and energy flux. These diverse mass-energy flux subsystems collectively constitute a mineral system. All subsystems must operate interactively in space and time in order to form an economic mineral deposit. This symposium invites contributions on mineral systems modelling and new developments in the field.

Keywords: Mineral systems approach, exploration targeting, prospectivity analysis
39.2 Mineral Prospectivity Modelling: State of the Art
E John M Carranza ejmcarranza@gmail.com (South Africa), Alok Porwal (India)

Alok and John hold PhD in model-based mineral prospectivity modelling and are well-known experts in the field of mineral prospectivity modelling, with wide ranging academic and industry experience.

Model-based mineral prospectivity mapping is widely used as a predictive desktop tool for narrowing down target areas for ground exploration at different scales ranging from regional to the deposit level. The input geological features are considered spatial proxies of the mineralization processes and are termed predictor or evidential maps. The integration functions that are used in mineral prospectivity modelling vary from simple arithmetic or logical operators to complex mathematical functions. In this symposium models will be discussed either as data-driven or knowledge-driven depending on whether the function parameters are estimated heuristically based on expert-knowledge or empirically based on the spatial statistical relationships between the known deposits of the targeted type and the predictor maps.

Most geological phenomena are too complex to be resolved by the reductionist approach – i.e. observations at macroscopic level cannot be explained by analyses at microscopic level. These phenomena typically happen over a range of length- and time-scales and often lie in between two extremes -- the ordered, deterministic and predictable limit, and the unpredictable chaotic limit, which may still be deterministic.
There have been multiple studies that have revealed the presence of chaos in geophysical records as diverse as rainfall, temperature, river flow, oxygen isotope concentration, geopotential values and solar radio pulsation among others. The complex systems related with earth and its environment have also been found to self-organise themselves, and in the course of evolution they reach critical states that can be studied using the well-developed framework of ‘self-organised-criticality’. Some systems are driven by regular assimilation of energy in incremental amounts. They stay far from equilibrium and can produce sudden bursts of large amounts of accumulated energy when a threshold is exceeded by an incremental addition of energy.
Furthermore, geophysical phenomena tend to exhibit characteristic scale-free behaviour over a range of length- and time-scales. A large number of studies have used the concepts of fractals, percolation and diffusion-limited aggregation, seemingly belonging to the realm of disordered systems, to unravel the intricacies of geological phenomena such as diagenesis and antisintering in sedimentary rocks to name just a few. Power-laws abound and one finds a range of fractal dimensions of surface fractals as well as volume or mass fractals giving vital insights into geophysical mechanisms.
Since the analysis and characterisation of geophysical space–time data from the viewpoint for chaos and fractals requires an interdisciplinary approach involving mathematicians, physicists and geoscientists, this symposia intends to provide a platform to discuss these approaches.

Earthquake interaction and triggering takes place during and after the occurrence of an event. At comparatively short distances, triggered events are known as aftershocks and occur specially around the main shock. However, it is still not clear whether static stress change from permanent fault displacement, quasi-static stress change from post-seismic deformation, or dynamic stress change from passing seismic waves plays the most important role in triggering aftershocks. Transient dynamic stresses carried by large-amplitude surface waves decrease slowly with distance and play a more important role in triggering events at long range. The evidence for dynamic triggering occurring in many parts of the world takes the form of earthquakes and tremors occurring at the time, or soon after, the passage of the surface waves. However, their mechanism is not yet understood. In some cases, foreshocks occur shortly before subsequent large earthquakes in the same region. This can be interpreted as a triggering effect (the smaller triggering the larger) or as a nucleation process (the smaller being part of the preparation process for the larger), sometimes associated with slow slip events inferred from geodetic data. This symposium will discuss the forefront of current research in this rapidly-advancing field.

The ubiquity of extreme events in recent years highlights the need for the quantification of their characteristic features, such as their occurrence probabilities and intensities, which are essential for societal response in prevention and resilience. The inter-relationship between climate change and climate extremes is an essential element in their modelling and prediction and a framework for a comprehensive analysis is needed. The complex systems framework, in which a large number of components of a system interact nonlinearly to yield complex behaviour, such as emergence, is well suited for such analyses. The data-driven modelling and prediction of nonlinear dynamical systems based on extensive data (Big Data) have provided many new insights and forecasting tools in many disciplines, including weather, space weather, climate change. These techniques are machine learning systems based on the dynamical systems theory and provide new directions in harnessing the data revolution and artificial intelligence. The key aspects of these approaches are the modelling, and prediction from the inherent features in the observational data, independent of modelling assumptions, and dynamic uncertainty quantification with event probabilities or likelihoods. The symposium will address these aspects in the extreme events, such as earthquakes, floods, droughts, hurricanes, tornadoes, and space storms and their variability. The complex systems with Bayesian machine intelligenceframework provide an approach for integrating the analysis of the extreme events, natural hazard and their variability, impacts of geological processes/ feed-back mechanism/ inter-relationship to climate change. The quantification of non-linear processes and their characteristics are the key features of these phenomena and highlighted as the central theme of the symposium.

Knowledge of hydrological processes and reservoir system is crucial for comprehensive understanding of the hydrologic cycle including the water quality analysis or management. Water is dynamic and strong solvent and it possesses different qualities as encountered with various natural and anthropogenic factors due to human activities or climate change. Modeling the spatio-temporal reservoir dynamics and hydrological processes, controlled by the complex systems of water supplying resources such as lakes, rivers, and reservoirs, has always been encouraged by the global hydrological community. Challenges still remain, in particular lack of proper models and in situ measured data, uncertainty analysis due to climate change and human activities, lack in knowledge of water exchange processes, etc. This symposium aims to discuss these challenges and recommend feasible solutions including latest technological developments in the modeling of hydrological processes and changes in reservoir or river system. We welcome theoretical and modeling work from pore to regional scale as well as both laboratory and field experimental contributions covering topics that include, but not limited to, simulation and modeling of hydrological processes and relevant changes in rivers, reservoirs and greater urbanized areas; hydrological model development and uncertainty analysis; disturbance hydrology; change in hydrological processes and reservoir system due to climate changes or human activity; critical water resource issues including reservoir operations and river flooding; advances in hydrogeophysics for reservoir characterization; case studies.

Many types of geological events such as earthquakes, magmatic activities, anomalous earth heat flux, and mineralization occurred in the earth lithosphere are of extreme nature due to origination of phase transition, self-organized criticality and multiplicative cascades. The common characteristics of these types of extreme events include scaling and singularity of their products such as energy release within short time scale or mass accumulation within short space scale. The energy and mass density distributions caused by these types of processes are of singularity which need nonlinear theory and models to describe. This Symposium welcomes proposals for sessions in a broad scope of applications of fractal, multifractals and other scaling theories in modelling extreme geological events in solid earth system.

Geophysical inversions are key problems in earth sciences. We determine the physical properties of the earth using geophysical data collected by gravity, magnetic, electromagnetic, seismic and other methods. The inversion methods provide the theoretical foundation and practical means to find information about the sub-surface geology from the observed geophysical data. Over the last decades, significant progress has been made in all aspects of geophysical inversions.
This symposium is therefore dedicated to recent advances in geophysical inversion methods, optimization theories and techniques, and their applications to the solution of regional-scale and deposit-scale geophysical and geological problems. Special focus will be made on developing theoretical principles and practical tools for integration and joint inversion of multiphysics data and constructing the shared earth models. We also invite papers on the case studies of applications of cooperative and joint inversions in different geological settings and in different geographical regions.

Deccan Traps are considered as one of the largest eruptions on the surface, covering 0.51 × 106 km2 area in the west and central India. Its eruption coincided with the K-T boundary biological mass extinction, perhaps the most violent in the Earth’s geological history. Besides, this terrain remains highly earthquake prone, having witnessed large number of damaging earthquakes in the recent past, such as 1967 Koyna, 1993 Killari, 1997 Jabalpur and 2001 Bhuj. In spite of several geological, geophysical and seismotectonic investigations, the nature of the crystalline basement concealed below the thick volcanic cover however, seems to have been studied least. Insignificant information is available that too is primarily based on the scanty seismological investigations or from the rocks exposed close to its periphery. Thus, to understand thoroughly, physical, compositional and thermo-geodynamical nature of the underlying Neoarchean crust, which lie below the Deccan Traps, has become a major challenge for geoscientific community.
 The objective of this Symposium is therefore, to invite innovative contributions based on multi-parametric geological, geochemical, mineralogical and geophysical investigations, to understand evolutionary nature of the crystalline basement and underlying mantle processes that may provide a new insight into the crustal evolution, particularly of this segment of the Peninsular shield. Comparison with the basement of other global volcanic terrains is encouraged. Besides, contributions related to the advances in seismic imaging in sub-volcanic terrains is also welcome.

It is well-known that CO2 utilization does not scale in regards to both magnitude and time of carbon storage required to positively impact climate. However, since utilization of CO2 most often requires high-purity CO2 as a feedstock, purification of CO2 from a dilute stream (e.g., air, industrial sources, natural gas or coal-fired power plant exhaust streams) is a required component of the utilization pathway. This purification step, whether it involves concentrating CO2 from air or a more concentrated point source, will be a required step for both utilization and geologic storage. Due to the lack of economic incentive today to inject and permanently store CO2 underground, utilization provides a pathway toward the generation of a carbon market. Research that focuses on the broad range of CO2 utlliization opportunities is of interest as the promising technologies will lead to demonstration-scale projects and public acceptance of displacing natural CO2 with anthropogenic CO2. Increasing demonstration-scale projects for utilization will inevitably lead to a decrease in the cost of the purification step, which will directly lead to reduced costs for conventional carbon capture with subsequent reliable storage. Hence, in the absence of adequate economic incentive to capture and permanently store CO2, utilization is a necessary intermediate step.

42.3 CO2 Storage/ Trapping Mechanism
Qi Li qli@whrsm.ac.cn (China)

Qi Li is Life Member of International Association for Mathematical Geology, Member of International Association for Engineering Geology and Environment, International Society of Rock Mechanics and Society of Petroleum Engineers.

The mitigation of carbon dioxide (CO2) emissions has become one of big issues in the world. Subsurface storage and utilization of captured anthropogenic CO2 (CCUS) provides a promising technology to decrease the rate of increase of CO2 in the atmosphere. The CCUS is characterized as an interdisciplinary R&D technology in energy geosciences between the basic science (geology, geophysics and geochemistry) and the reservoir engineering (site selection, reservoir geomechanics and potential evaluation). This symposium focuses on the fundamental aspects of understanding the fate of CO2 injected into deep reservoirs, the multi-physical, biogeochemical, and coupled interactions among CO2-brines, minerals, and hydrocarbons, and utilization strategies of CO2 in the subsurface (e.g. enhanced geothermal system, subsurface energy storage, and unconventional resources recovery by CO2). This symposium also welcomes innovated laboratory technologies and field investigations associated with fault reactivation and seal remediation during the large-scale sequestration and utilization of CO2.

42.4 CO2 Storage Associated with Enhanced Oil Recovery
Richard A.Esposito raesposi@southernco.com (USA)

Richard A. Esposito has over 28 years of experience in the electric utility industry in various roles and currently serves as Southern Company’s R&D Program Manager of Geosciences & Carbon Management. He works with a wide range of energy-related issues including Carbon Capture, Utilization, and Storage (CCUS), utility-scale energy storage, geothermal power, and deep well disposal of wastewater. Richard has a B.S. and M.S. degree in Geology and a PhD in Engineering with a focus on geologic storage capacity estimation in saline reservoirs, CO2-EOR pilot injection testing and certification of storage associated with CO2-EOR.

CO2-Enhaned Oil Recovery (CO2-EOR) is the process of using wells to inject CO2 at pressures where CO2 mixes with the oil, changing its properties, and increases the volume of oil extracted from an oil field. At the same time, oil fields provide the geologic framework for large scale storage of CO2 both associated with CO2-EOR operations or after the oil field is depleted. CO2-EOR projects are designed as a closed-loop system whereby some of the injected CO2 is co-produced with the oil and then separated in above-ground recycling facilities prior to being re-injected into the oil field. Each cycle of injection results in a volume of CO2 that is trapped is referred to as “associated storage”. This “associated storage” volume of CO2 has direct environmental benefits as the oil field can serves as a safe and long-term storage opportunity that values the injected CO2 as a commodity.  Demonstrating the safe long-term containment of CO2 in association with CO2-EOR and documenting the quantity of that CO2 stored is a driver in the expansion of EOR operations with use of anthropogenic CO2 that would otherwise be emitted to the atmosphere.  The understanding oil field operations and the documentation of “associated storage” is important to CO2 generators especially given a price on carbon or tax incentive for secure storage. This symposium invites case studies from oil fields whereby CO2-EOR operations were performed to evaluate this value proposition including parallel efforts such as the development of standards for storage of CO2 in oil fields.

43.1 Exploration and Mining for Kimberlites
Biplob Chatterjee biplob.chatterjee@geovale.com (India)

There is a unique connection between India and diamond. All through the history India dominated diamond production. Presently, nine out of ten diamonds recovered from diamond mines in different parts of world enters India for cutting and polishing before they travel to international market. Indian lapidary is the best in the world, particularly outstanding in handling the small size stones. It employs about a million people and continues to earn significant chunk of foreign exchange to the country.
Often unique and innovative methodologies are warranted for exploration strategies for kimberlites and related rocks as source of diamonds. This is largely due to geology of a terrain and emplacement mechanism of the kimberlite as well as its geometry.
This symposium will address current geological, geophysical, geochemical exploration tools for discovering kimberlites. Innovative multi-disciplinary methodologies from specific case histories of successful exploration programs are expected to be discussed.

43.2 Emplacement of Kimberlites and related rocks
Barbara Scott barbara@scottsmithpetrology.com (Canada)

Understanding the emplacement processes and mechanisms of kimberlites and related rocks have an impact on the economics of the mining operations. In order to better constrain the mining conditions, predicatability and economics of operations, it is crucial to understand the emplacement processes.
The architecture of kimberlite pipes, sheets, dykes etc. is significant in terms of mine design processes. Orebody geometry, contact zones, internal structures occurrence of country rock xenoliths could directly influence pit wall stability, underground mining method selection.
The objective of this symposium is to illustrate some of the relevant mining issues and help to justify emplacement model studies that are vital for the understanding of primary diamond deposits.
The scientific aspects of the emplacement mechanism of the kimberlites and related rocks such as role of volatiles, composition of melts and constituent minerals would also be discussed in this symposium

43.3 Petrology of Kimberlites and related rocks
S. C. Patel scpatel@iitb.ac.in (India)

The petrology of kimberlites and related rocks has direct bearing on the formation of their enigmatic origin. The nomenclature and classification of the kimberlites and related rocks are crucial in understanding their genesis and emplacement processes.
The constituent mineralogy and chemistry of the kimberlites and related rocks also has bearing on the diamond potentiality of the kimberlites in terms of ambient oxygen fugacity conditions, diamond resorption rates and local geotherms.
These aspects would form the primary areas for the scientific discussion during the symposium.

43.4 Mafic, Ultramafic Xenoliths and Xenocrysts: Physical and Chemical Architecture of the Subcontinental Lithospheric Mantle (SCLM)
Stephen Haggerty haggerty@fiu.edu (USA)

Understanding the sub-continental lithosperic mantle (SCLM) is crucial as any perturbations in it could result in large scale volcanism, magmatism and tectonism.
This symposium will address lateral and vertical heterogeneities within the SCLM from different cratonic blocks of India and the world based on the xenoliths and xenocrysts from the kimberlites and related rocks emplaced through the geological time scale. Additional point of discussion will be large-scale thermal perturbations during the geological past that include juvenile crustal additions and recycling events based on petrological, geochemical and isotopic studies on xenoliths, xenocrysts.

43.5 Deep Mantle Processes: Petrological, Geochemical and Isotopic Studies from Mantle Xenoliths and Xenocrysts
Sebastian Tappe sebastiant@uj.ac.za (South Africa)

Mantle xenoliths and xenocrysts from kimberlites are considered to be “real time snap shots” into the inaccessible deep mantle. Although Geophysics offers current day insights into the mantle, kimberlite-borne xenoliths and xenocrysts are probably the only source to understand physico-chemical processes in deep mantle. Studies on these mantle representatives from cratons world over during the last few decades provided great insights into the mantle processes such as sources of thermal anomalies, generation of magmas and their crystallisation, emplacement of mantle-derived melts, recycling of the continental masses, metasomatism etc. The main aim of this symposium is to review the latest on the above aspects.

43.6 Recipes for Diamonds: Evidences from Fluids and Inclusions
J.N.Das jndas7@gmail.com (India)

Diamond is an exotic mineral from the time immemorial. The formation and stability of diamonds and their transport to the surface always attracted the attention of geoscientists. Understanding the recipes for the diamonds within the mantle such as parental fluids, conditions for the formation of diamonds and crystallisation mechanisms and stability conditions is the primary theme of this symposium. The studies on the source of carbon both crustal and mantle-derived would be discussed in this symposium. Mineral, metallic and fluid inclusions in diamonds as proxies to understand the deep mantle processes during their crystallisation would be another aspect for discussion.

Prof. Mukherjee has more than 25 years of experience in teaching and research in environmental sciences. He is basically a geologist, has supervised a number of doctoral theses and also led the research projects both at national and International levels. He is presently dean of the SES.

Prof. Atiqur Rahman has multiple degree in Geography and geoinformatics. He has about 20 years’ experience of teaching and carried out basic research in the field of remote sensing. He completed a number of important projects with greater social relevance.

Satellite remote sensing together with GIS provides an opportunity for better observation and more systematic analysis of various geomorphic units, lineament features, following the integration with the help of Geographical Information System to demarcate the groundwater potential zones. The remote sensing data helps in fairly accurate hydro-geomorphological analysis and identification and delineation of land features. There are a wide-range of global remote sensing data sets (TRMM, SSM/I, Landsat TM, AVHRR, AMSR-E, ASTER, etc.) supported by aerial methods and ground truth by multi sensor, as well as hyperspectral information. Geomorphological variability due to tectonic activity coupled with land use/land cover changes inferred by geospatial techniques can be useful tool. The Gravity Recovery and Climate Experiment (GRACE) twin-satellite data is another important data which provides a direct measure of monthly total water storage at regional level. These advanced methods are being used for microzonation of groundwater potential locations and its quality assessment by inferring landforms, geological structures and vegetation indices on the aquifers. This symposia intends to focus on the subsurface water investigation on difficult areas of Earth and other planets.

D supervision and leading various national and international projects. Currently he is heading the Hydrogeophysics Research Group devoted to research in high resolution mapping methods for groundwater resources and data integration

Dr. Subash Chandra is a core scientist of Indo-French Centre for Groundwater Research. Dr. Chandra has been working in several national and international projects dealing with hydrogeological problems in different problematic terrain in India. He has played key role in introducing airborne geophysics in the field of Hydrogeology in India. He is currently leading couple of projects on Airborne Geophysics for aquifer mapping, smart city, etc.

Mapping of the near surface of the Earth for generating precise knowledgebase for most of the natural resources (viz., water and mineral) and structural settings is gaining importance with the time. Particularly the groundwater resources are dynamic in nature that vary with space and time depending on the geological variability, degree of heterogeneity and rate of exploitation. Whether groundwater budgeting or siting a sustainable well or managing groundwater recharge, etc., it need to be dealt at regional scale. Such mapping faces two major issues i.e. (i) optimally dense data in accordance with the degree of variability and (ii) rapid measurement to cover regional scale for comprehensive knowledge.
Airborne geophysical mapping addresses both the issues. With the technological advancement airborne electromagnetic and magnetic methods have been globally accepted as proven non-invasive technologies to provide high-resolution (meter scale) and comprehensive map at large (watershed/basin) scale rapidly. Airborne geophysical are increasingly being employed widely for groundwater mapping and have produced very encouraging and exceptional results. It is time now to discuss and compare the results obtained in different countries and design improvements both in data acquisition and interpretations. The symposia is aimed to provide ample opportunity to share the latest technologies, emerging methodologies on processing and interpretation and findings on high-resolution 3D geophysical mapping using airborne geophysical methods

Dr. Prabhat C. Chandra is an extremely experienced Geophysicist carried out extensive work on Geophysical survey using electrical methods. He developed a large number of new techniques for effectively carrying out Electrical survey and their interpretation.

Mr. Kishore C. Naik is presently the chairman of the CGWB, a premier government organization responsible for the groundwater resource. He is an engineer cum hydrogeologist and has widely worked in different terrenes.

The near-surface geophysical methods and techniques distinctively provide adequate subsurface information economically. However, the hydrogeological transformation of geophysical attributes is complex. But, it is an essential, important and challenging process to characterize the subsurface lithologic and groundwater conditions adequately or at least to get a satisfactory realization of the dominant conditions. Complexity in lithology combined with spatial hydrogeological heterogeneities complicates the transformation and therefore integration of geophysical methods is in vogue to discriminate or characterize the lithology and hydraulic properties and come out of the uncertainties and the nonlinearities. The parameters provided by different surface and subsurface geophysical methods like electrical, electromagnetic, seismic, magnetic, gravimetry and radiometry at varied scales and resolutions through their conventional and tomographic approaches and the geologic and hydraulic information are being quantitatively converged using a common inversion strategy to estimate the lithologic and hydrogeological properties accurately which would not have been possible independently through any discrete method. The session provides ample opportunity to present and share with the gathering of the international community of geoscientists the latest researches, innovative and economic approaches, emerging trends and findings on the challenging issues of lithologic and aquifer characterization.

Dr. Rana Chaterjee basically geologist but has worked as hydrogeologist in the Central Ground Water Board where he gained about 20 years’ experience working in a number of real life projects in groundwater exploration and management.

Although overall water on the Earth virtually remains constant, the increasing population and associated increase in the water utilization towards irrigation, industrial and domestic needs, etc. are stressing the natural water resources system. Over past few decades’ groundwater utilization towards irrigation also have increased significantly causing dwindling of the groundwater level. Specially the hard rock that covers roughly 20% land surface of the Earth are more affected due to its limited aquifer thickness. In the receding groundwater level condition, fractures are now the main contributor to the hard rock hydrogeology. Thus the knowledge of the fractures in hard rock is topic of interest in this symposium in contexts of:

  • reservoir exploitation for water supply;
  • contamination from subsurface waste repositories;
  • geotechnical applications including effects on underground storage reservoirs, tunnels and other structures);
  • Managed aquifer recharge and development of groundwater resources; and
  • locating potential zones for tube well, etc.

This symposium is aimed to provide a global platform to present and share the latest researches, innovative and economic approaches on geologic and geotechnical characterization of the fracture pathways and its groundwater potentiality in hard rocks.

Prof. Mohammed Israil from the Department of Earth Sciences, Indian Institute of Technology Roorkee is an experienced geophysicist with a long experience of post graduate teaching and research in the field of Electrical and Electromagnetic methods of Geophysical exploration.

Dr. Sarah from the Earth Sciences Department of Kashmir University is an experienced hydrogeologist. Carried out extensive research in hard rock hydrogeology and developed new methods of analysing hydrogeological parameters.This session shall focus on the Mineralogy, Petrology, Spectroscopic studies of planetary materials (including soil, minerals and rocks) using field, laboratory and remote sensing studies of the planets of the solar system. The session shall include all aspects of comparative study of asteroids, planets of the solar system and their moons using terrestrial analogues.

The analogy between electrical and hydrological parameters exists since a long time e.g., Archie’s law as well as the simulation of groundwater flow using a network of R-C analogues. Determination of the electrical properties or electrical parameters of an aquifer system is economical and non-invasive compared to direct estimation of hydrogeological parameters. There has been tremendous research and publications on the use of Dar-Zarrouk (D-Z) parameters estimated from Geophysical (Vertical Electrical Soundings or Electrical Resistivity Tomography) data. This symposium is expected to discuss various aspects of translating the geophysical parameters into hydrogeological parameters with a direct or indirect relations as well as constraining the estimates of hydrogeological parameters with the economically known geophysical parameters through non-invasive methods.

Dr. Jainendra K. Rai is basically a geophysicist but has extensively worked in hydrogeophysics. He handled various projects of multi-disciplinary both National and International. Has served in various managerial posts and looking after the groundwater division of WAPCOS Ltd.

Rapid urban growth, industrialization and climate variations are emerging as major challenges to sustainable and eco-friendly development. In particular supply of good quality drinking water and unpolluted groundwater for agriculture, managed artificial recharge assume great significance. Similarly, rising sea levels due to global warming are causing severe stress in coastal regions due incursion of saline water. To find sustainable solutions to these problems, ground and airborne geophysical investigations are being increasingly employed in different parts of the world. In addition, there are many other problems relating to rapid urbanization like: Site evaluation to construct Metro, underground facilities like parking, storage, ring roads, bridges and flyovers, locating sites for waste dump/disposal, pharmaceutical plants, etc. All these problems necessitate geophysical, geological and borehole studies at local or regional scale depending on the problem. Contributions dealing with various geological and geophysical aspects of the abovementioned problems are invited in this symposium.

45.1 Hillslope process and climate change
Mauro Soldati (Italy), Sunil Kumar De desunil@yahoo.com (India), Mihai Micu (Romania)
International Association of Geomorphologists (IAG)

Climate change may be due to natural processes internal to the Earth system or to external forcing agents to the anthropogenic modification of the composition of the atmosphere and/or of land cover.
Climate changes affect the stability of natural and engineered slopes and have consequences on landslides. But the type, extent, magnitude and direction of the changes in the stability conditions, and on the location, abundance, activity and frequency of landslides in response to the projected climate changes is unclear till toady. Climate acts on landslide processes through the highly nonlinear soil–water system, and no unique relationships exist between certain climate conditions and the occurrence of landslides. We can assume that the connection between climate – in particular, positive (or negative) hydrological balance – and landslide activity (or inactivity) exists at every timescale, from daily to millennial. Thus, climate and landslides act at only partially overlapping spatial and temporal scales, complicating the evaluation of the climate impacts on landslides.
Keeping in view the aforesaid problem this session is going to be proposed to highlight the issues on the relationships between hillslope processes and climate change. Hazard and risk issues related to the possible increase in frequency and magnitude of slope instability processes from global warming and more intense rainfall will be discussed in this session along with emphasis on the expected consequences for human activities and on possible mitigation measures.

45.2 Geomorphological Hazards and Risks mitigation through new techniques
Bianca Vieira (Brazil), Sunando Bandyopadhyay odnanus@gmail.com (India), Helene Petschko (Austria) International Association of Geomorphologists (IAG) Working Group on GEOMORPHOLOGICAL HAZARDS (IAGGeomhaz)

The frequency and magnitude of occurring geomorphic hazards has increased enormously throughout the world in response to the current and complex environmental and climate changes. Increasing anthropogenic impacts on environment are also expected to gain more spatial consistency, affecting the current land use/cover patterns, posing greater challenges for the management of geomorphic risks at local/regional/national levels. In order to achieve this goal, complex morphologic, morphogenetic and morphodynamic studies should be performed as the basis for proper susceptibility and hazard studies. In this session, presentations addressing both processes and their associated consequences are highly welcomed, targeting studies on local and regional impacts of volcanic, glacial, pluvial, fluvial and gravitational processes with relevance for land degradation assessments and improvement of existing approaches for geomorphic hazard and risk analysis at different scales. The overall purpose of this session is to highlight, through representative case-studies, the importance of geomorphic hazards studies for risk mitigation, the latest scientific advancements in Geomorphology, including new techniques and methods for geomorphic mapping, natural hazards inventory, risk analysis, numerical models, geochronological methods, UAV survey, digital elevation models, GIS resources, reduction of societal effects and increase of human communities’ resilience under the observed and projected climate and environmental change.

45.3 Status of mineral resources of SAARC nations for cooperative mineral-based industries
O. P. Verma igcroorkee@gmail.com (India) Indian Geological Congress

The above theme had been in my mind for several years for compilation of relevant data on mineral and energy resources of SAARC nations for posterity and to make use of them for added value, better quality of life of the people, creation of greater employment and development of advanced technologies. The programme will also go for developing homelier relations between the member countries, which have to be developed today or tomorrow by resolving differences, particularly between India and Pakistan – the two big neighbours. In addition to the above benefits accruing from discussing the above theme at the 36th IGC, I may point out that utilization of minerals for finished or semi-finished products & promoting clusters and zones of production of indigenous minerals and then export to earn greater revenue creation of cluster zones of minerals for cooperative industries in SAARC region should also ensure better use of electricity and water, besides human resources. These measures, I am confident, would integrate regional economies, friendly environment among the concerned nations and also help integration with global value chains, apart from strengthening indigenous infrastructure and connectivity. SEGMITE from Pakistan is all for it. We also have a new government there keen to develop trade by adopting split policy. Sustainable minerals’ supplies are inherently essential for the sustainability of any mineral-based industry – be it domestic, or by imports, bartered trade, or cooperative supplies from friendly countries. Although India is one of the rich countries in mineral resources, no country is self sufficient in its requirements so also is the case for India. SAARC nations, a group of close-net countries, by give and take, can be considered to have cooperative mineral-based industries like steel, aluminium, cement, petroleum, base metals, coal, power generation, etc., one day or the other on friendly ties.

45.6 Symposia/Sessions proposed by YES Network

45.6.1 Shear Zones and Crustal Deformations (SZCD)

Durga Prasanna Mohanty durgamohanty.online@gmail.com (India), Ankush Singh (USA)

In recent years the study of geological deformation features focuses upon the mechanics of crustal-scale brittle failure in extensional and convergent tectonic zones. Current research activities on deformational features take a relook at the shear zone structures with new kinematic and dynamic models. Shear Zones are the most significant crustal features with concentrated deformations which accommodate an import regional or local strain rate beyond the strength of the country rock. Highly deformed rocks like mylonites, are most significant in terms of kinematic and dynamic analysis of complex structures in field as well as in microscopic structures. The proposed theme is to bring the current developments in studies on rock deformation structures using field study, analogue and numerical model experiments.

45.6.2 Water: Sustainability for Life (WS)
N. Srinivasa Rao srinarukula@gmail.com (India), Md. Taufique Warsi (India), Faisal Kamal Zaidi (UAE)

Water is the essential natural resource for the evolution and sustenance of life on the Earth. The freshwater availability is a major driver to sustain the human and industrial needs in the Anthropocene. The resources are used in an unsustainable manner and rapid exploitation of the water resources leading to water scarcity problems. The growing population, food security and the modern living standards demand more water, which keeps the world river basins under stress. On the other hand, streamflow depletion, declining groundwater levels and increased human interventions have altered the terrestrial hydrological cycle over the time. To tackle the global water problems with human interventions, we require innovative strategies and solutions. The current theme primarily focused on addressing the water crisis problems, both quantitatively and qualitatively and their uncertainties, which draws attention to create a balance between the demand and supply of water resources and to debate the sustainable development in line of the United Nations Sustainable Development Goals (UNU SDGs). The high uncertainty in prediction of water-related variables requires an integrated and quantitative understanding of the changes in water cycle storages and fluxes, including precipitation, evapotranspiration, soil moisture, surface water, groundwater, snow, and glaciers. Also, recent developments in satellite observations provide immense support for prediction and forecast of water quality and hydrological modelling, which can provide the best estimates of water, climate and anthropogenic variables. Further, effective translation of scientific results can provide better decision support to policymakers and water managers to create functional policies and regulations. We are happy to welcome authors to submit their abstracts about their recent findings on water-related issues and special importance will be given to the issues related to global change, groundwater dynamics, water scarcity, water quality status and remediation.

Geoscience has evolved into an interdisciplinary science allowing synthesis of unprecedented approach from various disciplines that helps in development and improved understanding of the planet Earth, and its evolution. Geochemists often address a diverse range of topics in Earth Science system with broad interests in diverse fields such as, crustal evolution, weathering and erosion, ocean-atmosphere coupling, paleoclimate, oceanography and palaeoceanography, ocean redox evolution, etc to quantifyvarious processes operating on Earth with an aim to understand its past, present and future. With the advent of technological advancements in instrumentation (mass spectrometry), novel advances in analytical techniques (non-traditional stable isotopes)and consolidation of various experimental and modelling approaches, it has become possible to understand various Earth System processes in much more details. The present theme provides an opportunity to researchers working at the forefront of closely allied fields in geoscience and apply multidisciplinary approach to address various scientific questions related to the origin and evolution of our planet. Some of the substantial areas covered under this theme include chemical oceanography, paleoclimate, radiometric geochronology, isotope geochemistry and other interdisciplinary branches of geoscience. The present theme invites papers that can address various scientific questions using integrated approaches in geosciences.

Srikumar Roy (UK)

With the increasing trend of societal needs and scientific developments, near surface exploration for groundwater, minerals and energy resources is obsoleting rapidly. The continuous exploration of natural resources from the several decades has vanished now the possibility of finding required natural resources in near surface and forced us to look for the possible natural resources towards the deeper subsurface, ocean resources and the areas like mud volcanoes followed by coastal deposits for heavy minerals. Proper understanding of the resources offered by the world’s oceans are very little known to us. In particular, exploration and production of energy resources pose colossal geoscientific challenges and is a highly argumentative issue due to the associated environmental risks. Development of new tools or methodology to address and decipher those challenges involved with the existing as well as new energy resources becomes essential. For this session, we encourage contributions from studies related to, but not limited to, advancement in geophysical methodology as applied to conventional/unconventional oil & gas, gas-hydrate, geothermal, mineral and water resources exploration; reservoir characterization including seismic, well log-based and sample-based studies as well as modelling that provide new insights in natural resource exploration.

45.6.6 Tectonics, Surface Processes and Climate
Sajid Ali sajidali7861@gmail.com (India), Madhav K. Murari (Germany

Methodological progress in quantifying rates of surface processes in the upstream erosion and transfer zones as well as revived interest in the coupling between surface processes, tectonics and climate have made it possible to renew our understanding of the interactions between sedimentation and tectonics within the framework of the whole integrated sediment routing system. In this session, interaction between climate-tectonics and surface process will be discussed.

45.6.7 Hydrogeophysical Studies for Vadose Zone Characterizations
Tanvi Arora tanvi@ngri.res.in (India)

The unsaturated zone is often the main sector controlling water movement from the land surface to the aquifer. Thus it strongly affects the rate of aquifer recharge, critical for the use and management of ground water. It is often regarded as a filter that removes undesirable substances. To some extent this is true, but a more general fact is that flow rates and chemical reactions in the unsaturated zone control whether, where, and how fast contaminants enter ground-water supplies. Understanding of unsaturated-zone processes is therefore crucial in determining the amount and quality of ground water that is available for human use. This zone has been described thoroughly and conceptual model prepared is to be employed in the study. Time Lapse methods can monitor moisture changes in soil over time. Time Lapse Electrical Resistivity Tomography (TLERT) data is used, as the hydrogeophysical study, to characterize and monitor the unsaturated zone of the different terrain.

45.6.8 Non-invasive Geophysical Methods and Numerical Modelling for Groundwater Resources Exploitation and Management
Payal Rani payal.gpy@gmail.com (India), Zoi Dokou (USA)

Geophysical data are being increasingly used to provide qualitative and quantitative information about hydrogeological processes. Some of the many topics that hydrogeophysics actively contributed are contaminant transport, recharge monitoring, surface and groundwater interactions. Geophysical methods potentially provide subsurface data with high spatial and temporal resolution in a non-invasive manner. This session will be focused on the use of geophysical methods for the characterization of subsurface properties and processes in contexts such as hydrology, agriculture, contaminant transport, etc. The researchers who are working on integrated approaches of geophysics and numerical analysis also including laboratory and field experiments; relevant hydrogeological and hydrogeophysical case studies, numerical modeling for groundwater resources and on contamination problems, are encouraged to apply in this session.

45.6.9 Multi-proxy Approach in Paleo Monsoon Reconstruction During Quaternary Period
Upasana S. Banerji upasana.s.banerji@gmail.com (India), Chandana K.R. (India)

There is an unprecedented need to understand the present climate trends which reinvigorated the past climate reconstruction beyond instrumental records. A number of marine as well as continental archives have recorded past precipitation-temperature variations and thus illustrated the long-term variability in the climate system. Geochemical, isotopic and palynological approaches have been a valuable tool that provide integrated signals of various processes that led to the evolution and variation in the monsoon system. However, there still remains a lacuna in understanding the impacts of ocean-atmospheric processes and natural forcing factors on the monsoon system that prevailed on the planet Earth. The present session invites contributions towards Quaternary climate reconstruction using natural archives such as sediments, speleothems, corals, ice cores etc. using multiproxy approach.

45.6.10 Quaternary Landform Evolution in a Mountainous Landscape
Rahul Devrani rahuldevrani18@gmail.com (India), Anil Kumar (India)

The exogenic and endogenic processes fundamentally governs the evolution of landforms in the mountain belts. A diverse range of landforms, evolved in glacial, fluvial and hillslope environment provide foremost records of any changes in the climatic and tectonic settings of a mountain belt. The interaction between geomorphological processes during Quaternary period should provide an order of correlation in evolution of these landforms. However, it is not evident due to the geological diversity present in the mountain ranges. An increasing integration of multidisciplinary studies i.e. field studies, geochronology, geomorphometry, new conceptual methods, modelling etc. at different temporal and spatial scale is significantly improving our understanding in landform evolution. The primary aim for this session is to understand evolution of landforms in a mountainous landscape during Quaternary period. To address the diversity of landforms in a mountainous landscape, we welcome glacial, fluvial and hillslope process based studies. For this session, we invite contributions that uses geomorphic or sedimentary records to understand landform evolution. We also encourage studies which directly address coupling between earth surfaces processes and tectonics at range of spatial scale in mountainous region.

45.6.11 Forward Modelling of Present Day Continents: Challenges and Solutions
Ravi Shankar ravisingh82.2@gmail.com (India), R. V. Gireesh (India)

The dynamic nature of Earth is reflected by continuous and periodic changes on its surface i.e., earth’s crust, from its advent at about 4.55 Ga to present. These changes are manifested by episodic amalgamation and dispersal of continents forming and breaking supercontinents.
In last couple of decades, the study of paleogeographic configurations of paleo-supercontinents has picked pace and that has resulted in high quality Geochronology, Paleomagnetic, Geological, Geophysical data input at discreet intervals in Earth’s history.
This theme will aim to understand the challenges in potential use of such dataset to forward model the super continental configurations and will also try to infer possible solution to such challenges.
Considering the rapid evolution in scientific tools and techniques and advent in computational capacity used in earth sciences, it is desirable to frame such an approach which can actually predict the future geological events. Such models can be extremely useful for sustainability entire human society.

45.6.12 Advances in Earth and Planetary Sciences
Rajeev Kumar Yadav rs123.bhu@gmail.com (India), Ramdayal Singh (India)

The advancement in the techniques and ease of capturability and processing of geophysical and geological data in the past two decades has elevated the understanding of Earth and Planetary System Processes. The imaging of Earth and Planets from the space-based techniques has provides a vast opportunity in detail exploration of crustal deformation, mass redistribution, vegetation growth, weather prediction, geohazards, surveying and mapping. Availability of various observation field provides the opportunity for interdisciplinary work on the development of a new approach to deal with complex problems. For example, the past geodetic and paleo-seismological studies in the Himalaya suggest a large potency of future great earthquakes in the frontal zone of Himalaya but the processes governing the crustal deformation to sustain the accumulated strain energy prior to megathrust earthquake is not known.

45.6.13 Geochemical Signatures of Paleo Monsoon Variability
Barnita Banerjee barnita.gem@gmail.com (India), Mahjoor Ahmad Lone (Taiwan)

The Asian monsoon which affects Indian subcontinent and southeast part of the Asia, is probably the most important monsoon system of the world. Despite its vast influence, the forcing mechanisms that control the timing and intensity of the Asian monsoon are still debated. The livelihood of over three billion people is dependents on the annual summer rainfall known as the Indian summer monsoon. Since India is an agro-based economy, any change in monsoon rainfall has great impact on common masses. Intense heavy rainfall leads to flooding and breaks in monsoon or a weak monsoon leads to water shortage and drought. The Indian monsoon is apparently the most grounded articulation of Earth's coupled hydroclimate, involving large inter hemispheric exchanges of mass and energy among the ocean, atmosphere and landmasses Reconstructing the long-term variability of Indian monsoon circulation is therefore necessary for understanding monsoon dynamics across all time scales and to assess the direction and impacts of future changes. For this session, we welcome contributions using geochemistry of paleoclimate archives to study the monsoon history. The focus of this session will be on the past variability of the entire Asian monsoon system, including the Indian and southeast Asian monsoon subsystems.

45.6.14 Understanding the Earth Structure and Mantle Dynamics through Geophysical Observations
Padma Rao B padmarao.india@gmail.com (India), Sunil Rohilla (India), Sunil Roy (India),
Dipankar Saikia (India)

Knowledge of the internal layering of the Earth has been largely derived using the different geophysical tools. The conditions on the surface of our mother earth, mostly depend on the mantle dynamics/convection of the earth controlled by the mantle properties. The surface geodynamic processes like the subduction, mid-oceanic ridges are directly linked to the mantle processes. Recent studies shed light on the sinking of these slabs deep into the lower mantle and perhaps to the core-mantle boundary (CMB). This region plays a crucial role in the mantle convection process and is one of the unexplored regions of the earth. In order to understand the mantle dynamics and its characteristics, it is essential to investigate the mantle structure through various geophysical techniques. Investigating the mantle structure is crucial to understand the deeper earth and its link to the tectonic activity. This will also shed light on the knowledge to validate the tectonic models, an origin of the plate motion and the role of mantle rheology. However, due to the intricacies of the link between the deformation mechanisms and the flow patterns of the mantle needs the interdisciplinary approach for the better understanding. Thus, characterizing the mantle structure through various geophysical techniques will provide a better understanding of mantle dynamics, which is the key component to gain knowledge on the evolution of our mother earth.

45.6.15 Geodynamic Significance and Mineralization Potential of the Precambrian Ultramafic Complex
Niranjan Mohanty niranjanmohanty9090@gmail.com (India), Abhinay Sharma (India)

Geodynamics and metallogenesis have been major thrust area of the earth science. It provides a better understanding of the thermal evolution of the earth as well as it gives an insight into the origin of the continental crust associated with potential mineralization. Ultramafic rocks are very important but poorly understood component of the Precambrian greenstone belts and tonalite-tronjhemite-granodiorite (TTG) basement terranes. Many issues remain unsolved regarding the relationship between origin, geodynamic evolution and mineralization potential during the crustal evolution of the earth. The theme of this provides a synoptic view on geodynamic processes, mineralization as well as quantify the crust mantle interaction covering various segments of different continents of the world. it also gives an idea on the alteration zones, their style and controls on such as gold, PGE and base metals and also brought out the idea on secondary mineralization. The aim of this session will help to examine the relationship between Precambrian ultramafic complex and mineralization potential.

Elemental cycling such as carbon and nitrogen in terrestrial and coastal systems play critical role in cropping cycle, monsoonal patterns and climate. Biological communities are essential to biogeochemical cycling of carbon and nitrogen and their functions are controlled by numerous factors including energy sources, redox conditions and availability of trace metals. Moreover, the structure of biological communities including bacteria and archaea have consequences for biogeochemical cycling. We welcome submissions from early career scientists working on different aspects of carbon and nitrogen cycling spanning across terrestrial, coastal and marine environments. In particular, scientists addressing challenging problems related to carbon and nitrogen budget from local to global scales are also encouraged.

Life on Earth had already originated by 3.8 billion years ago and experienced sustained and steady evolution during the Precambrian. Biodiversity exponentially increased following the events associated with Snowball Earth during the latest Neoproterozoic, and became highly diverse through a series of major but linked biodiversifications from the latest Neoproterozoic to the Early Paleozoic. The Earth life system also suffered major crises during the Phanerozoic including the biggest five mass extinctions. Associated with the evolution of life and biodiversity changes are dramatic environmental and climate fluctuations of the biosphere and earth system. This session will explore the evolution of life and biodiversity changes through deep time based on fossil data, and utilize various analytic approaches to address diversity changes and their links to climate and the environment. We also highlight various studies that use temporal frameworks to aid in the interpretation of biological history and processes, such as mass extinctions and their recovery, the processes of initiation and escape from crises, and long-term, large-scale evolutionary patterns and trends.

Sedimentary and paleoclimate systems evolve dynamically through deep-time. Fundamental knowledge about the evolution of sedimentary and paleoclimate systems may be achieved if we have enough data within a 4-dimensional context. By the rapid expansion of geoscience data and development of new techniques on data integration (e.g. artificial intelligence, data mining), more and more global or regional sedimentary and palaeo-climatic datasets has been generated. These datasets can provide us novel insights into the evolution of sedimentary and paleoclimate systems and to discuss their change patterns and mechanisms. Thus within this broad topic, we are inviting big data-driven contributions on deep-time source to sink systems, paleo-sedimentary flux and distribution, paleo-environment change, etc. The analyzed big data may source from disciplines including, but not limited to sedimentology, sedimentary chemistry, paleoclimate, palaeo-oceanography, Earth system sciences etc.

Tectonic forces exert a primary control on the geography of the Earth’s surface at present day, and how this has evolved through deep geological time. A wide range of data are now available to quantify tectonic deformation and the feedbacks between tectonics, deep Earth processes, surface landscape evolution, and climate. By piecing these data together, we can reconstruct the history of tectonics on Earth across a range of scales, from individual fractures and faults, to sedimentary basins, orogens, and ultimately global plate tectonics. In this session we invite presentations that quantitatively analyze tectonics and crustal deformation across all spatial and temporal scales, with the aim of stimulating discussion on how new methods and databases can contribute towards the fundamental goal of reconstructing Earth’s tectonic history in four dimensions.

The volume of digital data that is becoming available to the global geosciences community is increasing at an exponential rate as a consequence of new technologies, open science policies, and investments into data infrastructure. At the same time, new data science methodologies including Artificial Intelligence and Machine Learning have opened up previously unimaginable opportunities to mine and analyze these vast volumes of Earth observations, promising fundamental new and groundbreaking discoveries. In order to fully take advantage of these rapidly expanding opportunities, the currently highly fragmented and globally distributed data resources in the geosciences need to be better aligned and networked through common data exchange protocols and policies. The development of open platforms such as the Deep-time Digital Earth are essential to support access, integration, and analysis of the data. This session encourages participation from key stakeholders in the development, operation, and use of geoscience research data infrastructure, including but not limited to data providers, data scientists, and geoscientists to discuss needs and requirements, achievements, opportunities, and challenges for realizing the vision of the Deep-time Digital Earth.

The Deep Time Digital Earth (DDE) project has just been approved as the first of the International Union of Geological Science (IUGS) ‘Big Science’ programs and its aim is to harmonize deep time geological data. Through DDE, data will be available in easily used ‘hubs’ providing insights into the distribution and value of earth resources and materials, as well as earth hazards. Data brought together in new ways may provide novel glimpses into the Earth’s geological past and its future. The hubs will likely derive from, and be valuable to, both Geological Survey Organisations (GSOs) and industry. This session will explore how DDE may work with GSOs and industry, the mechanisms of interaction, the areas of interest, the possible barriers to progress, and the opportunities.

Dinosaurs are a major vertebrate group that attracts a great deal of attention from both academic researchers and the general public. Their documented evolution records some major transitions, including the evolution of powered flight from terrestrial animals and the extraordinary development of gigantic body size (which includes the largest known land animals). Dinosaur evolution is also characterized by dramatic changes in species diversity such as the rapid diversification and dominance of dinosaurs after one or two extinction events in the Late Triassic and the sudden disappearance of all non-avialan and a number of avialan dinosaur lineages during the Cretaceous-Paleogene mass extinction. This session will focus on topics pertaining to dinosaur macroevolution, including both taxonomic diversity, and morphological and ecological changes through space, time, and phylogeny, in addition to body size evolution, and the evolution of bird-like features associated with bird origin. We also discuss how an approach centered on a database will help to advance dinosaur macroevolutionary research, and how to build an integrated database for both the academic community and the general public to achieve goals for academic research and wider science popularization.

We are on the brink of a revolution in understanding orogenesis, the timing and trajectory of crustal growth and the nature of related lithospheric and deeper mantle processes. We have 21st century tools to apply to an Earth System approach to probe the workings of our planet through time. These include: advances in geochemical analysis technology, geochronology methodologies, and experimental capabilities that are yielding extensive new datasets; global and regional geophysical datasets; and computer modelling power to apply to tectonic and geodynamic modelling. Integrating these different datasets will enable unprecedented imaging and modelling of the effects of different orogenic processes from the Archean to the present day.

This session aims to: (1) explore the impact of such recent advances relevant to accretionary, collisional and intracratonic processes by big data analysis of geophysical properties, petrology, geochronology/isotope/element distribution geochemistry, and petrology, (2) explore possible differences in crustal formation, architecture and preservation between accretionary and collisional orogens; and (3) to better understand the role of orogenic provinces in shaping the surface and resource availability of our planet Earth.

This session provides comprehensive guidelines of geohazards and geoinformation technology. The subject has a link to geoheritage. Geohazards occurred in many places and pose serious threats to the human societies and the natural environments. A number of geoheritage sites which should be preserved for future generation are also in danger. The main challenge is to put together all scientific and multi-disciplinary tools including geohazards survey technology and geoinformation technology. The geohazards survey technology is required for comprehensive understanding, assessing and monitoring. The geoinformation technology, such as data integration, spatial analysis, visualization, and modelling of multi-disciplinary geospatial datasets, is necessary for providing timely advice on their occurrence, and suggesting relevant risk reduction measures. As the survey and geoinformation technology are developing rapidly, so It is essential to learn the advanced technology for reduction of disasters. In this context, the well-established guidelines of geohazards surveys and geoinformation technology not only for scientists, authorities and community leaders but also for leaders in emerging regions and the public are required. Another challenge is that the guidelines are concerned with science and engineering. This session will overarch the two fields and focus on survey technology, geoinformation technology, risk management technology and comprehensive guidelines of their technology.

Change in natural systems and associated processes accelerated by anthropogenic interventions, has been inducing unforeseen complexities in the process of development and sustainability. The need and scope for utility of geosciences knowledge is pervading almost all fields of life on the Earth apart from the management of natural resources and a healthy environment. The multiple scale interactions of ecosystems with the process-response characteristics of both living and non-living resources and systems are observed to control the productivity and sustainability.

The Sustainable Development Goals (SDGs) adopted by the United Nations aspiringly aim to end global poverty, fight injustice and inequality, and ensure environmental sustainability by 2030. Various geosciences aspects like climate change, energy resources, agro-geoscience, engineering and environmental geology, geohazards, water resources, mineral and rock resources significantly contribute to the realization of all most all the agreed SDGs. The achievements of geoscience community and the contributions made by earth science institutions with be deliberated mostly by invited speakers. Though the presentations are likely to focus on India, the deliberations will reflect and impact the developing nations of the world.

45.11 40 years with International Lithosphere Program (ILP)

 

Proposer: International Lithosphere Program (ILP)

Hans Thybo, Magdalena Scheck-Wenderoth, Alexander Rudloff

International Lithosphere Program (ILP) has since 1980 been promoting international, multidisciplinary research programs to elucidate the nature, dynamics, origin and evolution of the lithosphere. ILP has taken initiative to more than 70 programmes within its four research themes: (1) Geoscience of Global Change, (2) Contemporary Dynamics and Deep Processes, (3) Continental Lithosphere and (4) Oceanic Lithosphere. Example programmes initiated by ILP include World Stress Map, Global Strain Rate Map, Global Seismic Hazard Assessment Map, Global Impact project, International Continental Drilling Program (ICDP), and a series of Global Geoscience Transects and programs. Present programs focus on integrated mapping of lithosphere physical parameters, lithosphere dynamics including the fate of subducted lithosphere and deformation of continental lithosphere, volcanism, response of the lithosphere to surface processes including changes in climate and erosion/deposition dynamics, and mineral resources. ILP promotes high class science in combination with community services through the Evgueni Burov medal for mid-career scientists and the Flinn-Hart Award for outstanding early-career scientists. The activities of ILP seeks to achieve a balance between: "addressing societal needs" in regard to e.g. natural catastrophes, resource exploration and environmental protection; and "satisfying scientific curiosity" in regard to global and regional processes affecting the lithosphere.

We invite all scientists to present their recent research on lithosphere formation, structure and evolution. The session will provide an overview of key results through the 40 years’ history of ILP. We particularly invite the teams of the ILP task forces and coordinating committees to present new results of their international and multidisciplinary cooperation networks.

Critical metals are becoming more and more essential for our society in terms of their broad use in high-technology applications, but their supplies are inherently in secure, hence people are paying increasing attention to critical mineral resources nowadays. In this context, this theme focuses on the ore-related minerals, ore genesis and regional metallogeny of critical metal mineralization related to granitic systems. What are the regional-, district-, and deposit- scale geological characteristics of critical mineral deposits related to granitic rocks? What are the key features of ore and gangue minerals of the granite-related critical metal ore systems?

How do the critical elements migrate and accumulate during the granite-related critical metal mineralization? Studies on the geology, geochemistry, mineralogy, and geochronology of critical metal ore deposits related to granitic rocks provide crucial information to address these questions. Other fundamental aspects, including but not limited to, experimental studies, theoretical modeling, and the application of new techniques (e.g., metal isotopes) to characterize the behavior of those elements within fluids are also helpful to understand these scientific enigmas.

Human civilization and enhancement of living standard are the result of development activities. Urbanization, industrialization, exploration and exploitation of natural resources and construction of roads, highways, dams and bridges are the major development activities going on worldwide. Unfortunately, such development activities are also causing global warming, air and water pollution, health hazards, and broadly speaking, degrading the natural environment necessary for the survival and welfare of the mankind.

We want development in order to improve the standard of our living. And at the same time, we also want to preserve our natural environment. The motto of this symposium is for exchanging ideas, concepts and activities in geosciences, the science of the earth and also for recommending ways and initiatives for sustainable development.

Conceding the role of groundwater is essential for successful implementation of sustainable resource development goals. Groundwater has become central to human development and it is generally preferred over surface water because of the relatively safe quality and quantity. As a result, groundwater is overexploited in many parts of the world and hence needs demand and supply side management to safe guard the drinking water supply sources and food security. Apart from this, groundwater contamination due to lithologic composition and anthropogenic activities is on hike viz. fluoride, arsenic and nitrate. Thus, it is an urgent need to address these issues especially in context with the low - income countries. The objective of this symposium is to provide a platform for exchanging ideas, concepts and activities of the geoscientists worldwide, and also for proposing the ways and initiatives towards sustainable groundwater development.

There has to be more interaction between the society and the Geologists in-charge of developing earth resources for the use of the society. The society has to know about the process of exploration and exploitation of the earth resources and the environmental impact of resource exploitation. This would help in prudent use of these resources by the society. Geoscientists should consider it as their duty to write popular science articles in newspapers and magazines stressing the importance of conservation, re-use and re-circulation. In other words, the society has to learn about ‘Resourcing the Future Generation”.

The Indian Ocean composes most of the Indian-Australian Plate. It is a wonderful geological playground which encompasses a large variety of geodynamic settings. The oceanic crust had a complex evolution with several directions and rates of spreading, a triple junction and the occurrence of Large Igneous Province volcanics. The crust displays core complexes and large transforms and the rifting has isolated pieces of continental crust representing submerged continents. The Indian Ocean also suffered intraplate deformation within the oceanic lithosphere around 9Ma ago. The margins illustrate different types of tectonic evolution with a passive margin type in Western Australia, Eastern and Western India, and Antarctica, abrupt margins with strong bathymetric gradients and large strike-slip faults in Eastern Africa (Owen FZ) and the Warton Basin, the Ornachnal FZ in Pakistan, and the Ninetyeast Ridge. In addition, convergent systems are present all over in the northern part of the ocean with accretionary wedges in Makran and Sunda, coupled with very active seismicity responsible for catastrophic earthquakes and tsunamis. Very oblique subduction is present from North Sumatra, to Bangladesh via Malaysia Thailand and Myanmar, with associated wrench tectonics (Indo-Burman Range and Andaman-Sagaing FZ). The Northernmost part of the Indian Plate is marked by continental subduction in the Himalayas and Pamir.

This symposium, initially constructed around a CGMW-UNESCO project of Geological Mapping of the Indian Ocean, will welcome papers discussing large objects in and around the Indian Plate, and will try to link the timing and kinematics of the plate with the geological structures of the margins.

Korea, the host country of the 37th IGC, is known as the Land of Morning Calm because of its natural beauty and splendid tranquility, particularly in the morning. Contrary to this poetic expression, Korea has not been consistently calm in geologic history, which is reflected by the diversity and complexity of lithologies (igneous, sedimentary, and metamorphic rocks), formation ages (Archean to Quaternary), and deformation structures (folds and faults). In fact, internal and peripheral orogens in East Asia tend to converge towards the Korean Peninsula situated in a tectonic link between cratonic Asia and an outboard magmatic arc. A wealth of variety preserved in the peninsula provides an excellent opportunity to investigate the magmatic and structural responses to the individual collisional and accretionary orogenies and their interplay, the evolution of volcanic/magmatic activity from continental arc, back-arc to intraplate settings, and the geologic histories of marine to nonmarine and strike-slip to extensional sedimentary basins. The sublinear distribution of Quaternary faults in SE Korea, Quaternary to historical volcanic activities recognized from Baekdusan, Jeju and Ulleung Islands, and recent seismicity collectively indicate that Korea is more active than previously thought. This symposium intends to address landmark presentations on tectonic, magmatic, volcanic, and sedimentary evolution of the Korean Peninsula and other East Asian regions between Precambrian and Quaternary as constrained by geological, geochronological, geochemical,numerical, and geophysical data.
