Abstract: Fukang fault zone is located in piedmont of Bogda mountain in Junggar basin. Influenced by superimpositions of multistage subtectonic movements of the Hercynian, Yanshan and Himalayan, its structural deformation and hydrocarbon accumulation process were complicated. Comprehensive geological studies suggest that at the late of Early Permian the Bogda trough began to closing, forming the foreland halfgraben?like depression of the Middle Permian Jiangjunmiao depositional stage in the piedmont of Bogda mountain, above which the lagoon facies dolomitic shale of the Middle Permian Pingdiquan formation is the major hydrocarbon source rock in this area; the Yanshan movement period that occurred three episodes of strong movements is the main reconstructive stage in Fukang fault zone; the powerful extrusion stress of Himalayan movement allows Fukang fault zone’s footwall to develop the halfgraben?like sag of thrust?type foreland basin and the thrust nappe at upper wall. The three?stage strong tectonic movements control the structural framework and hydrocarbon accumulation in this area
