- Abstract:
- Zhongguai uplift in Junggar Basin experiences multi stages of tectonic movements. The superimposition and alteration mineralization of faults are strong, forming complex fault systems. According to the new collected high-precision 3D seismic data, the fault systems in Zhongguai uplift were interpreted, and the superimposed relation of different fault systems identified was discussed. The results show that the faults in Zhongguai uplift can be divided into thrust fault, normal fault and strike-slip fault, which have significant differences; according to the types, scale, activity and formation mechanism of these faults, the fault systems in Zhongguai uplift include Carboniferous-Permian compression and thrust fault system, Triassic-Jurassic transpressive and strike-slip fault system and Cretaceous-Neogene extensive normal fault system; according to the difference of fault occurrence, corresponding relation of faults in plane and in profile, and genetic relationship with boundary fault, the faults in plane can be subdivided into the thrust-slip fault group in the east of well Hong3, the thrust-slip fault group in the east of well 598, the thrust-slip fault group in the east of Hongshanzui, the thrust fault group in the south of Wuqu, the thrustweak slip fault group in Karamay, and the thrust-slip fault group in the east of well Guai6; the structure and combination of each fault group are unique individually; according to the tectonic evolution setting in the northwestern margin of Junggar Basin, combined with balance section restoration, the fault systems in Zhongguai uplift can be divided into Permian compression and thrust stage, Triassic-Jurassic transpressive stage and Cretaceous-Neogene tilted extensive stage.
