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 litholo gic,especially the paleotogic characteristics observed. The assumption is t hat the Upper Permian series should exist in Aduogabu which is in Xiadong T own, Gaize County, Tibet. This assumption was verified by the results of pa leontologic identification. Accordingly it can be concluded that the idea o f the lacuna of the Upper Permian series in Gangdise- Nyainqentanylha strat igraphic area should be reconsidered. There also exist abundant fossils suc h as coral, foraminifera,brachiopada and algae, which are representative of the result from warm water fauna. There exist some pinnacle reels consisti ng of coral and/or stramatopora. All this reflects the location evolution o f Tibet in the area from high to low latitudes.
