摘要
通过对吴堡断裂带构造综合研究与分析,采用分期、分区、分类的工作思路,以里德尔单剪模式为依据,考虑力学机制、构造演化等综合因素,完成了吴堡断裂带构造样式成因分析,认为吴堡断裂带尽管在剖面上处于伸展构造系统的地段,但在平面上出现走滑构造的构造样式成因的雁列式组合,区内构造既有剪切又有拉张成因,为走滑-伸展复合型构造成因,今后的工作难点是分辨不同断层的成因。
The tectonic style and genesis of Wubao fault zone is analyzed with consideration of mechanics and tectonic evolution based on Riedel single shear model with the working thought of studying by stages,by zones and by classes. It is concluded that the Wubao fault zone vertically occurs in extensional tectonics but laterally shows en echelon style of strike-slip structure,with the structure genesis involving both shear action and extension,belonging to composite strike-slip-extension tectonic origin. The difficulty in future work will be to discriminate fault genesis.
