英文摘要: Abstract(#br)In the Indo–Gangetic plains (IGP), the inter–basinal area between the Ganga in east and the Indus in west is currently devoid of any major drainage. A wide paleochannel belt, the Ghaggar-Hakra channel, has been mapped in this region. Our previous studies along with others established that a large Himalayan river flowed through this paleochannel, and a large–scale drainage reorganisation occurred during the last 10 ka. This follow-up study presents sedimentary facies and chrono–stratigraphy of the alluvial deposits from the Ghaggar-Hakra paleochannel (1) to understand the depositional environments of the river system; (2) to reconstruct aggradation/incision history and stratigraphic development, and (3) to understand fluvial response to climate change at a regional scale....
