The record of climate and uplift in the palaeo-Ganga plain: A way to decipher the interactions between climate and tectonics

Foreland basin sediments provide a record of the tectonic and climatic processes that control the morphologic evolution of mountain belts, through their sedimentological, geochemical and geophysical characteristics. The Siwalik continental molasses were deposited in the Tertiary Himalayan foreland basin. These sediments represent the record of more than 15 Ma of Himalayan denudation. They consist of fluvial deposits strongly influenced by the Neogene tectonics of the mountain belt. Also the climatic changes that affected the area are recorded in them. A multidisciplinary study has been conducted in the Siwaliks of Nepal in order to decipher the interactions between climate and tectonics.
