Abstract：The southwest margin of Buerhanbuda Mountain belongs to the hinterland of the East Kunlun orogenic belt, and it has strong regional tectonic effects since late Archean. In the Middle Permian, several nearly parallel EW deep fractures were formed in the study area with successive closure of ocean basins in multiple islands of the East Kunlun region, which are the main framework of Kunzhong fault zone. Through the analysis of landform, remote-sensing images, geophysical exploration, lithostratigraphy, deformation and metamorphism, the structure of fault, microstructure, the authors in this research summarized the main characteristics of the faults and clarified the structural framework in the area. Besides, the southern boundary of Kunzhong fault zone which has not been recognized has been discussed, and the results show that Wenleng'en fault belongs to the southern boundary of Kunzhong fault zone. This research would provide some reference for the related geological issues.
