Abstract: As the exploration direction transfers to orogenic belt in the northwestern margin of Junggar Basin, the thrust belt of Zaire Mountain has become the exploration focus. Previously, the thrust belt is thought to be typical over-thrust and nappe belt, but the fault space composition relationships on the seismic sections show thrust\strike-slip-fault belt characteristics. The whole system of thrust\strike-slip-fault belt can be divided into two stages. The first stage is thrust-nappe during Carboniferous to Permian, and the second stage is thrust-torsion strike-slip during Triassic to Jurassic. In the physical simulation experiment, the characteristics and style changes of strata and fault in the two stages above are simulated, and it is confirmed that the thrust\strike-slip system really exists. Summarizing the development rules, we induce "chuan" word style on the plane and "from" word model in profile. The establishment of geological model provides a new direction for understanding the whole northwestern margin structure system. At the same time, it plays an important role in seismic interpretation and well location selection, and it also provides guidance for further exploration.
