本文在分析山西断陷盆地带的各种地质、地球物理资料的基础上,用三维粘-弹塑性有限元方法对该断陷带的形成机制进行了模拟计算。表明山西断陷盆地带的形成是地壳深部的上隆作用和北东—南西向挤压应力场在深部隐伏断裂上派生的右旋滑动共同作用的结果。地壳深部的上隆是一个主要的不可忽视的因素。
Based on the analysis of various geological and geophysical data in the Shanxi fault-depression basin, the formation mechanism of the fault zone was simulated by the three-dimensional visco-elastic-plastic finite element method. It shows that the formation of the Shanxi rift basin is the result of the interaction between the uplift in the deep crust and the dextral slip derived from the deep subduction fracture of the NE-NS compressional stress field. Uplift in the deep crust is a major factor that can not be ignored.
