古董山断裂构造带位于塔里木盆地西部的巴楚隆起上,走向北西—南东,延伸140 km左右。基于地震剖面的详细解释,识别出4期构造变形:寒武—奥陶纪正断层、二叠纪正断层、中新世冲断层、上新世—更新世冲断层及其伴生的正断层。中新世基底卷入型冲断层是古董山构造带的主控断裂构造,构成断裂带的主体,构造变形样式为断层传播褶皱。寒武—奥陶纪正断层形成复式地垒,隐伏于中新世主干断层之下。二叠纪正断层可能伴生有岩浆活动。先存的正断层和岩浆岩对古董山中新世断裂活动具有明显的控制作用;后期的断裂活动,即上新世—更新世逆冲断层和正断层,对中新世形成的断裂构造有改造作用。古董山断裂带东南端与玛扎塔格构造带西端交汇,但两者不是同一条断裂带。
The Antigone Mountain fault zone is located on the Bachu uplift in the western part of the Tarim Basin and extends from northwest to southeast over an extension of 140 km. Based on the detailed interpretation of the seismic profiles, Phase 4 tectonic deformation was identified: the Cambrian-Ordovician normal fault, the Permian normal fault, the Miocene thrust fault, the Pliocene-Pleistocene thrust fault and its associated normal fault. The Miocene basement thrust fault is the dominant fault structure of the Guandishan tectonic belt and constitutes the main body of the fault zone. The tectonic deformation pattern is the fault propagation fold. The Cambrian-Ordovician normal fault formed a compound horst, hidden beneath the Miocene thrust fault. Permian normal faults may be associated with magmatic activity. The pre-existing normal and magmatic rocks have a significant control over the Miocene faulting in the Palaeozoic. The later fault activities, that is, the Pliocene-Pleistocene thrust and normal faults, have an effect on the faulting structure of the Miocene . The southwestern tip of the Guandishan fault junction meets the west end of the Mazatag tectonic belt, but the two are not the same fault zone.
