摘要
鄂尔多斯盆地西部冲断带是该盆地中最为复杂的构造单元,认识相对模糊且长期存在争议。在前人的研究基础上,通过西部冲断带的几何学、运动学和动力学分析,对鄂尔多斯盆地西部冲断带进行了详细的构造解析。西部冲断带构造样式在北部表现为对冲式,陶乐段为同向东倾断块,中部为滑脱式对冲断褶,南部具有走滑性质压扭斜冲式,具有幕式构造演化的特点。
The thrust belt in Western Ordos Basin is the most complex tectonic unit in the basin,and its understanding is relatively vague and controversial for a long time.On the basis of previous studies,through the geometry,kinematics and dynamics analysis of the Western thrust belt,a detailed structural analysis of the Western thrust belt in the Ordos Basin is carried out.The structural style of the Western thrust belt is thrust in the north,the Taole segment is a synclinal eastward dipping fault block,the central part is a slip-type thrust fold,and the southern part is a strike-slip compression-torsion oblique thrust,which is characterized by episodic tectonic evolution.
