摘要
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 fault,folding mechanism and the tectonic style distributing laterally and vertically,six sequences of structural styles and three evolution stages are induced in the Wuxia fault belt.The evolution of structural style is similar in east and west parts and different in middle part of the fault belt.The piggyback strong compression structural style was developed in the Permian stage,the overstep compression structural style in the Triassic-Jurassic stage and the tensional structural style in the Cretaceous-Tertiary stage.The basic control factors to the regular evolution of the structural style are regional geo-tectonic environment,basement nature,stress state,physical nature of rocks and stage of tectonic evolution.
