Recent sequence stratigraphy, facies distribution, and tectonic study of 92 remnant basins in the Qinghai-Tibet Plateau reveals the Cenozoic evolutionary history of the plateau. During the Paleocene-Eocene (65-34 million years BP), the southern Tibet and the Yecheng area in Xinjiang were parts of the Neo-Tethys remnant sea where coastal plain fluvial facies dominated the hinterland of the plateau. The Sunpa-Ganzi and eastern Tibet uplifting zone shrank easterly, and tectonic uplifting took place primarily along the Bangor and the Kunlun- Altyn Tagh zone on the NE margin of the plateau. Therefore, the plateau was higher in the northeast than in the southwest...
