Abstract:On the basis of clay, carbonate, pollen and ostracode, it presented the Late Pleistocene climate and environment of Zabuye saline lake in Northwestern Tibetan Plateau.In 60.3 ±2.7kaB.P.and 142.2 ±7.4kaB.P., it was a freshwater lake.Weathering was weak and physical weathering dominated.In 60.3 ±2.7kaB.P., the climate was cold and a little wet,as shown by the appearance of kalinite, and the salinity of water was higher than that of 142.2 ±7.4kaB, P.On the contrary, the climate was cold and a little dry in 142.2 ±7.4kaB.P., and there were many whole shells of ostracodes which implies the water was relatively ralni at that time.Iti addition,the Mg contents of caicite showed that the salinity of palaeo-Lake Zahuye during60.3±2.7kaB.P.was higher than in 142,2±7.4kaB, P.
