摘要
孔雀河地区受库鲁克塔格断隆与多期构造运动的影响,构造较为复杂。对该区有重要影响的断裂有孔雀河断裂、巴里英断裂、尉犁断裂和维马克-开屏断裂。本区经历了5个演化阶段:被动陆缘盆地阶段;挤压反转古鼻凸形成阶段;克拉通内凹陷阶段;克拉通内坳陷盆地发展阶段和类前陆盆地发展阶段。加里东末期的构造运动,奠定了下古生界的基本构造轮廓;燕山运动古生代构造再生;侏罗系构造基本定型;喜马拉雅运动使本区发育为类前陆盆地。古生界发育大型鼻凸,中生界以断背斜圈闭为主,依附于逆冲断裂。圈闭类型可划分为4大类、10小类,主要发育3种构造样式。
The structural features are complicated in Kongquehe area because of the influences of Kuluktag faulted uplift and multi-stage tectonic movements. The faults that affect the area most are Kongquehe fracture, Baliying fracture, Weili fracture and Weimake-Kaiping fracture. The area had undergone such evolution stages as passive borderland basining, squeeze-retrograde nose-like swelling, cratonic inner sagging, intraeratonie basining and para-foreland basin. Late Caledonian tectonic movement formed the basic structural configuration of the Lower Paleozoic; Yanshan movement regenerated Palaeozoic structures and shaped Jurassic structures; Himalayan movement made the area developed as a para-foreland basin. Large-scale nose-like swells were developed during the Palaeozoic era, while the Mesozoic was dominated by the faulted-anticline traps with thrust belt. The trap can be divided into four types and subdivided into ten kinds, and three structural styles were developed in this area.
