Niaoshan-Gudongshan structural joint is located at the boundary between Bachu rise and Maigaiti slope, western Tarim Basin. It was formed by intersection of Niaoshan, Manan, Mazhatage, Gudongshan and Luositage structural belts. And it's also near the closely related Shalong fault. The embryonic form of Nioashan-Gudongshan structural joint formed in Late Cretaceous, including Niaoshan, Luositage, and Mazhatage Late Cretaceous thrust belt and Manan Late Cretaceous compressive strike-slip fault belt. Manan fault is the adjustment zone between Niaoshan, Luositage structural belts in the west and Mazhatage structural belt in the east. The Late Cretaceous of structural deformation was controlled by the collision orogeny between South Qiangtang accompanied by Lhasa block and Asian continent. Niaoshan-Gudongshan structural joint basically finalized the evolution at the end of Miocene. With the wedging of Pamir tongue between Tarim and Karakum, the compressional stress diverted to compression-shear, resulting in the formation of a series of strike-slip faults in southwestern Tarim, including Mazhatage-Luositage Late Miocene strike-slip faults and Gudongshan fault as its derived fault. Late Cretaceous was the key formation period of the structures and traps in the studied area. The decollement-thrust structure with the bottom Paleogene salt layer as main decollement surfaces, formed in Late Pliocene to Early Holocene, protects the early traps and reservoirs. Niaoshan and Mazhatage tectonic belts are the most favorable oil and gas exploration zones in study area. Manan tectonic belt is an important oil and gas migration channel.
