Prof. Eglington is a world leader in database construction and management, and making data-rich global animations. Murray Pyke Chair,University of Saskatchewan


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, palaeomagnetism, 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.


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

Sedimentary records and Correlation of Supercontinent Crustal blocks

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.
