Abstract:
These step-by-step reconstructions in conjuction with unroofing data derived from the synorogenic sediments in the Himalayan foreland basin can produce a detailed record of erosion in the Himalayan thrust belt. Conventional point counting data and isotopic data from the Bhainskati Formation, Dumri Formation and Siwalik Group, which have been dated using magnetostratigraphy, reveal a rich unroofing record in western Nepal. Each step of the structural kinematic sequence from the forwards models is correlated with the unroofing data from the synorogenic sediment. This study is the first to combine kinematic data with unroofing data to produce a series of 'snap shots' of how the Himalaya looked with respect to erosion from 25 Ma to the present. This study explores the link between erosion and evolution of the Himalayan thrust belt and the feedback between these two processes in the resulting Himalayan-Tibetan Orogenic system.
