Clay Mineral and Geochemical Proxies for Intense Climate
The clay mineral assemblages and geochemical compositions of the Permian Talchir and Barakar mudstones of the Raniganj basin India have been used to interpret terrestrial paleoclimate The Talchir Formation presents unequivocal evidences of the Permian global glacial climate and the overlying Barakar Formation with braided fluvial deposits immediately follows the glacial amelioration stage
