Abstract

Infrared stimulated luminescence dating of sub-surface sediment core samples from about 350-190 m depths in Meerut and Yamuna Puram (Bulandshahr) regions of western Ganga Plain gave ages of 49-31 ka. Such sample depths and ages indicate rapid subsidence of the region during latest Pleistocene to create appropriate accommodation space in a relatively short time. Geochemical and clay mineralogical data indicate a humid climate during 50-30 ka. It is inferred that during 50-10 ka western Ganga Plain was rapidly subsiding and received large amount of sediment from the activity of Ganga Megafan.
