Sedimentology and geochronology of Mesoarchean siliciclastic successions of the Singhbhum Craton, India and their implications

Abstract

Terrigenous sedimentary successions provide solid evidence of subaerial exposure of continents and help to constrain the timing of continental emergence on early Earth. The Singhbhum Craton of India preserves an extensive record of Archean basin formation events. Although earlier researchers have worked on the southern, eastern, and western successions and have produced valuable sedimentological and geochronological data, the northern and northwestern Archean (tentatively) sedimentary successions (the Birtola and the Bisrampur formations) are not adequately studied and the geochronological data is poor. Herein we propose to undertake sedimentological and geochronological studies of these two formations. This study will explore the relationship with magmatism and sedimentation and source-to-sink relationships in the northern margin of the Singhbhum Craton to unravel the timing and nature of magmatism, basin development and source-to-sink relationships. The data generated in course of this research work will be used to test a previous hypothesis of continental emergence during the Mesoarchean. The research student associated with this project can submit his/her thesis for a Ph.D. degree. Effort will be made to publish three research papers in peer reviewed Earth Sciences journals and/or book.
