| 摘 要： | 结合高分辨率浅层地震剖面和区域地质资料，对汤西断裂浅部构造特征进行分析和讨论。结果表明，汤西断裂南段由2条走向NE、倾向SE的正断层组成，主断层下降盘汤阴地堑内新近系沉积明显增厚，结合探槽结果认为，汤西断裂南段的最新活动时代为中更新世。

| Abstract: | Combining high-resolution shallow seismic profiles and regional geological data, we analyze and discuss the shallow structural characteristic of Tangxi fault. The results show that the southern part of Tangxi fault is composed of two normal faults with NE strike and SE dip, and the Neogene sediments of down-thrown side of the main fault in Tangyin graben is obviously thickened. Combining with the results of trial trench, the latest active age of south section of Tangxi fault is middle Pleistocene. |
