Intense uplift of the Karakorum and Kunlun Mts.began from late Pliocene to early Pleistocene.The total amplitude of the uplift ranges from 3100m to 3600m.Due to the intense uplifting,climate over the Qinghai-Xizang(Tibetan)Plateau has been changed significantly which has exerted great impact on the developement of glaciations,loess deposition,interior lakes and drainage systems etc.Late Pleistocene was a very important stage for the climatic and environmental changes in the Karakorum and Kunlun Mts.and their adjacent areas where an arid process which started from the last glacial maximum(LGM)is still going on.
