Discovery of the Upper Permian series in Cuoqin Basin, Xizang (Tibet) and its geological significance

During the field work,one assumption has been made according to the lithologic,especially the paleotogic characteristics observed. The assumption is that the Upper Permian series should exist in Aduogabu which is in Xiadong Town, Gaize County, Tibet. This assumption was verified by the results of paleontologic identification. Accordingly it can be concluded that the idea of the lacuna of the Upper Permian series in Gangdise- Nyainqentanylha stratigraphic area should be reconsidered. There also exist abundant fossils such as coral, foraminifera,brachiopada and algae, which are representative of the result from warm water fauna. There exist some pinnacle reels consisting of coral and/or stramatopora. All this reflects the location evolution of Tibet in the area from high to low latitudes.
