| Venue: | Asima Chatterjee Lecture Theatre |
| Details: | Terrestrial sedimentary successions provide unambiguous evidence of subaerial exposure of continents. High resolution sedimentological analysis coupled with robust geochronological data are essential to constrain the timing of continental emergence on early Earth. The Singhbhum Craton of India preserves an extensive Archean terrestrial volcano-sedimentary record. Recent surge of geochronological data from the Archean sedimentary successions of the Singhbhum Craton provide us an opportunity to infer early Earth surface processes and crust-mantle interactions. Published sedimentological and geochronological data suggests non-deposition and/or erosion on the Singhbhum Craton and thus development of a prolonged unconformity along the northern margin of the Singhbhum Craton throughout the Neoarchean. These late Paleoarchean to Neoarchean terrestrial and near-coastal successions of Singhbhum Craton should be the prime targets for intense geobiological research to decode the mysteries of early Earth surface processes and co-evolution of life and surface environment. |
