Abstract: The Late Triassic Batang group in south Qinghai are located in the south of Jinshajiang suture, the research degree is relatively lower with the complicated geological structures, and still there are disputes in the division of the strata sequences. Based on 1∶〖KG-*2〗250000 regional geology investigation, the Batang group in this article was subdivided into lower Formation, middle Formation and upper Formation in ascending order by the actual section survey and the region contrast. This article analyzed the lithologic combination, the biota appearance, the geological age of the Batang group. At the same time, using the gravity current micrite, the pillow shape basalt, the Bouma sequence turbidite and the structure setting of volcanic rock, discuss preliminary the developing process of the sedimentary environments and tectonic settings in research area, our works have provided the basic data for the research of Batang group.
