| 摘 要： | 阐述了通过走滑活动断裂断错冲沟形成变形角研究冲沟形成年代，进而探讨断裂活动特征的方法。并以天桥沟－黄羊川断裂东段为例，对变形角大小和冲沟形成年代及冲沟水平断错距之间的关系进行了探讨，结果表明它们之间关系密切。最后论述了变形角用于走滑活动断裂研究的可能性及意义。

| Abstract: | The authors have introduced the way of studying gully ages and active characteristics of strike slip faults.Take the eastern Tianqiaogou Huangyangchan fault for example,they have analysed the relationships between the dislocation angles,gully ages and the gully displacement,and the result shows that those relationships are closely.The authors have also discussed the possibility of the dislocation angle application and its tectonic significance. |
