Title: An Analysis for Sedimentary System, Evolution, and Paleoclimate in the Litang Basin in West Sichuan in Quaternary
Abstract: Litang basin in Quaternary where sediments were predominated by fluviolacustrine was formed 0.747 Ma ago and consumed between 0.179~0.180 Ma ago. Space-time distribution of sediments in the basin reveals a discontinuous extended paleolake with multiple consumption and amyotrophy. Sporopollen association in the basin indicates a temperate and humid climate and an altitude of about 2000 m above sea level. Then, the paleoclimate became temperate and glaciation intensified headward erosion of the old Wuliang River which resulted in consumption of the lake. This evolutionary history provide important evidences for paleoclimate evolution on the Qinghai-Xizang Plateau.
