青藏高原北部东西延长超过1600km的东昆仑走滑活动断裂带由于中新世以来的持续走滑作用,沿断裂带形成长45～70km、宽8～12km的库赛湖、东温泉和托索湖等大型拉分盆地。位于昆仑山口以东的东温泉盆地连续沉积了厚达数千米的晚新生代湖相地层,为东昆仑走滑活动断裂带变形历史及青藏高原气候环境演化研究提供了理想的窗口。地质填图结果表明,东温泉盆地新生代地层自下而上由古新世-始新世沱沱河组(E_(1-2)t)、渐新世雅西措组(E_3y)、中新世五道梁组(N_1w)和上新世曲果组(N_21q)等时代不同的古
Due to the continuous strike-slip since the Miocene since the East Kunlun slip event extending over 1600km in the northern part of the Qinghai-Xizang Plateau, the Qusai Lake, the East Hot Spring and the Tusuohu Lake, extending 45 ~ 70km long and 8 ~ 12km wide, Other large sub-basin. The Late Cenozoic lacustrine facies, which is thousands of meters thick, is continuously deposited in the East Hot Spring Basin to the east of the Kunlun Pass. It provides an ideal window for the study of the deformation history of the strike-slip zone of the East Kunlun Mountains and the evolution of climate environment in the Qinghai-Tibet Plateau. The results of geologic mapping indicate that the Cenozoic strata in East Hot Spring Basin are composed of the Lower Paleocene-Eocene Tuotuohe Formation (E_ (1-2) t), Oligocene Yaxituo Formation (E_3y) The Wolong Formation (N_1w) and the Pliocene (N_21q) have different ages
