FIELD TRIPS

The Indian subcontinent, by virtue of being a constituent of several older supercontinents, has common geological ancestry with many parts of the globe. Subsequent to the breakup of the Gondwanaland, the Indian landmass moved northward for over 5000 km to collide and get stitched with the Asian landmass, resulting in the present landforms, typified by the Himalayan mountain chain. The subcontinent is also host to a wide range of geological marvels - from the Archaean crustal nuclei to the present day volcanism.

We welcome you to witness the congress/ scientific theme(s) showcased through an attractive assortment of pre-, post- and during-Congress field trips. The field trips have been designed to also include geotourism sites of unique cultural, historical and archaeological value so as to give a fulfilling and enriching experience of the tours to the participants. There will also be an interesting array of one-day trips during the Congress. Details of these trips will be made available in the Third Circular.

Description of the multi-day trips are given below. Full tour itineraries and cost will be released in the Third Circular. Delegates may choose field trips of their interest on the Congress website.

We take this opportunity to extend our invitation to you to join the field trips and be part of the journey, witnessing the unparalleled geological antiquity of the Indian subcontinent, the memories of which will remain with you forever.

Trip coordinator/s: Sudipto Neogi, Ravikant Vadlamani and Kathakali Bhattacharya

Causes for the metamorphism in abnormally thickened crust has been addressed involving thermal modelling, field studies, quantitative P-T estimation, geochronological and isotopic studies. An enigmatic feature of Himalayan metamorphism is the presence of a sequence of progressively higher grade rocks occurring at shallower structural levels, reported from the Darjeeling- Sikkim region, and later described with remarkable similarity from all along the nearly 2000 km length of the Himalaya referred to as "inverted" metamorphism.

BANGLADESH

68. INTBG001: Environmental Geology and Delta-Building Processes at the Mangrove Forest (Sundarbans)

This pre-IGC trip starts and ends at Sundarbans (along Delhi-Dhaka-Jessore route);

Participants: 90 max.; Duration: 4-5 days;

Trip coordinator: Director General, Geological Survey of Bangladesh

Trip overview: The Sundarbans is a vast mangrove forest in the coastal region in and around the delta of the Ganges, Brahmaputra and Meghna rivers at the Bay of Bengal. It was recognised in 1997 as a UNESCO World Heritage Site. Located at the south western part of Bangladesh, it is a cluster of islands with an approximate area of 3600 sq. km. forming the largest block of littoral forests with diversified assemblage of flora and fauna. Geoscientists will get the opportunity to experience active delta building processes, its complex network of tidal waterways, mudflats and small islands of salt-tolerant mangrove forests that presents an excellent example of ongoing ecological processes.

Geo-tourism spots: Sunderbans - a UNESCO World Heritage Site and the habitat of the Royal Bengal tiger.

69. INTBG002: Environmental & Quaternary Geology with Coral Island (St. Martin’s Island) Cox’s Bazar - St. Martin’s Island

This pre-IGC trip starts and ends in and around the Cox’s Bazar;

Participants: 100 max.; Duration: 4-5 days;

Trip coordinator: Director General, Geological Survey of Bangladesh

Trip overview: Cox’s Bazar is sandy beach with an unbroken length of 155 km making it the longest natural sea beach in the world. The sand at Cox’s Bazar beach and surrounding areas is rich in heavy-metal mineral content. St. Martin’s Island is a small island in the northeast part of the Bay of Bengal, about 9 km south of the tip of the Cox’s Bazar-Teknaf Peninsula. It is the only coral island in Bangladesh.

Geo-tourism spots: Himchari, Inanai, Maheshkhali etc.

70. INTBG003: Geological Exposure of Bangladesh (Sylhet)

This pre-IGC trip starts and ends at Sylhet (Delhi-Dhaka-Sylhet route)

Participants: 100 max.; Duration: 5 days;

Trip coordinator: Director General, Geological Survey of Bangladesh

Trip overview: Sylhet, located in the northeastern region of Bangladesh has a complex having diverse sacrificial geomorphology; high topography of Plio-Miocene age such as Khasi and Jaintia hills and small hillocks along the border. At the centre there is a vast low lying flood plain of recent origin with saucer shaped depressions, locally called Haors. Sari River section presents an excellent geological section for the Neogene (Mio-Pliocene) sequence in northeastern Bangladesh.

Geo-tourism spots: Jaflong, Sari river, Madhablunda etc.

SRI LANKA

71. INTSL001: Geology of the High-Grade Proterozoic Terrains of Sri Lanka

This post-IGC trip starts and ends at Colombo

Participants: 15 max.; Duration: 5 days;

Trip coordinators: L.R.K. Perera and Sanjeeva Malaviarachchi

Trip overview: Sri Lanka, the ‘pendant’ of Gondwana, is a collage of distinct crustal blocks that preserve important records of major Neoproterozoic tectonothermal events. The geology of Sri Lanka provides important insights into continental growth in the Neoproterozoic Earth. Tectonics of Sri Lanka has also been in focus in relation to the history of the assembly of supercontinents, particularly because of its central position within the India-Madagascar-Africa-East Antarctica collage of the late Neoproterozoic Gondwana supercontinent. Due to similarities of lithologies, geochronology of the rock in the Lützow- Holm Complex (LHC) of East Antarctica and the Highland Complex (HC) of Sri Lanka, several workers have considered that LHC as an extension of the HC of Sri Lanka. Hence speculation on the East Antarctic Geology may be done standing on Sri Lankan basement.

Geo-tourism spots: Dambulla Cave Temple, Wahawa Hotwater Spring and Dolerite dykes, Arrested charnockite around Kurunegala, Temple of Tooth etc.
