Abstract: The distribution of magmatic rocks of the Middle?Late Permian in western Tabei uplift controlled by the faults leads to the acidic volcanic rock distribution to EW in the uplift controlled by EW faults of the Carboniferous?Permian. The basalt merely distributed in Ying?maili swell and Halahatang sag is controlled by near?SN faults. The geochemical analysis indicates that the magmatic rocks in this study area belong to the intraplate volcanic rocks characterized by rift volcanic rock and the product of the late thermal event in the Early Permian large igneous rock province in Tarim basin
