The study area is geographically located in the northern side of Xar Moron River suture belt in the eastern Inner Mongolia and the southern Da Hingg’an Mountains and tectonically between the Sonidzuoqi-Xilinhot-southern Xi Ujimqin suture belt and Xar Moron River suture belt. It’s a key area for the study on the collision process between the northern margin of North China Plate and the blocks to the north. The results suggest that the previous Mid-Permian “Zhesi” Formation is probably a Late Permian or even Early Triassic sedimentary sequence. The provenance of the Permian sediments in Keqi and Linxi areas is mainly from Sonidzuoqi-Xilinhot-sourthern Xiujimqin magma arc in the north, and partly from the northern margin of North China Plate.
