Abstract:

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.

Key words: Junggar Basin, Wuxia fault belt, structural style, development sequence, evolution stage
