Abstract The Darabut fault appeared in the northeast strike across the West Jungger area is regarded as a big multiphase fault with a length of 480 kilometers through the interpretation of satellite digital image and the study of geological character. The Darabut fault does not control the strata of the lower Carboniferous and Precarboniferous Series, only leftlateral breaks can be seen; It obviously controls the strata of the middle Carboniferous and the lower-middle Jurassic ones ; Ultramafite in the Darabut ultrabasic rock is affected by the nappe tectonic, and then it locates in the up side of the Darabut fault. The formation and development of this system resulted from the continuous face-to-face movement of the Talim, Sibelian and Kazakhstanian continental segments after their collision and the early Carboniferous Epoch. As a type of the stress relief form, at the early stage (Triassic period, early and middle Jurassic Epoch) the system was turned into the plough-shaped faults by the strong nappe structure under the continental diving. At the late stage, it was in the state of extention, thus showing that the hanging wall went down. So the clear fault geomorphologic expression has been formed at pre-sent.
