| 摘 要： | 霍山山前断裂是山西临汾盆地北半部主边界断裂。本文根据沿断裂带的1:1万地质填图结果,详细地研究了霍山山前断裂的活动历史、断裂的分段性及其构造活动特征、不同时期以来的右旋错动幅度和滑动速率以及与1303年洪洞8级地震的关系。最后,根据山西地堑系内已获得滑动速率值的几条北北东向主干断裂的构造特殊性,讨论了地堑系两侧的一级右旋运动水平

| Abstract: | The piedmont fault of Mt. Huoshan is the main boundary fault in the northern part of Linfen basin. On the basis of geological mapping (scale: 1: 10000) along the fault, the authors have studied in detail the geological history, segmentations and structural features, the right-lateral dislocations and slip-rates of the fault since the later quaternary as well as their relation to the 1303 Hongdong earthquake (Ms=8). Finally, the first order right-lateral movement on both sides of Shanxi graben system has been discussed according to the structural peculiarities of NNE-trending major faults. |
