There exist two periods of genetically different granitoids in Sawuer Mountain of Xinjiang, whose Rb-Sr isotopic ages are 314.9~320.3 Ma and 295~296 Ma respectively. Based on these data in combination with their emplaced strata and their relations with volcanic rocks, it is considered that these two types of granitoids are of Middle and Late Hercynian respectively.
