The studied area is situated at the origin of the Yangtze River in the Tanggula Mountain of southern Qinghai, which was a part of the Qamdo Block of the East Tethyan tectonic domain during the Late Paleozoic and is bounded by the Jinshajiang suture to the north and the Lantsang-Lungmo Co suture to the south. The Permian strata is widespread in the area with various sedimentary facies, and separated by numerous and complicated faults, especially Lower Permian influenced by volcanic activity. As a result of complex regional tectonics and depositional types, there has been much controversy over the Lower Permian (Cisuralian) classification and correlation, which mainly involves issues including succession, age and regional correlation of volcanic rocks.
