在断裂、褶皱形成机制、构造样式分布平面分布和垂向分布研究的基础上,将准噶尔盆地乌夏断裂带构造样式的演化归为6种序列和3个演化阶段。构造样式演化具有明显的分区性,在断裂带东西两侧表现为相似性,中间则呈明显不同。3个演化阶段是指二叠纪前展式强烈压缩构造样式发育阶段、三叠纪—侏罗纪后展式压缩构造样式发育阶段和白垩纪—第三纪局部伸展构造样式发育阶段,而且构造样式的发育具有继承性和同沉积性。控制乌夏断裂带断层规律性发育的主要因素是区域构造环境、基底性质、应力作用方式和岩石力学性质等。
Based on the study of faults, fold formation mechanism, structural pattern distribution and vertical distribution, the evolution of tectonic pattern of Wuxia fault zone in Junggar Basin is classified into six sequences and three evolution stages. The tectonic style evolves with obvious zonation, showing similarities on the east and west sides of the fault zone, but distinctly different in the middle. The three evolution stages are the intensive compression tectonic style development stage of Permian foreshock, the developmental stage of Triassic-Jurassic post-show compression tectonic style and the Cretaceous-Tertiary local tectonic style development stage, The development of style has the inheritance and co-deposition. The main factors that control the regular development of faults in Wuxia fault zone are regional tectonic setting, basement properties, stress acting modes and rock mechanics properties.
