In this study an extensive investigation of representative Quaternary lacustrine sedimentary areas was carried out on the Qinghai-Tibetan Plateau. The investigated region extends from the Kunteyi Lake of Qaidam and Kunlun Pass southward to Jiangbu-Nyingchi, and eastward from Tianshuihai to Dêqên. This paper demonstrates that the Qaidam Basin is a fairly ideal area for the study of Late Cenozoic lacustrine sediments of the plateau. The authors suggest that a Late Cenozoic resource and environment scientific drilling project be implemented in the Qaidam Basin.
