| 摘 要： | 位于甘肃河西走廊中部、张掖——民乐盆地西侧的榆木山东麓断裂带,是一条走向北北西向晚第四纪活动断裂。根据断层地貌特征研究,断裂带显示为一高角度右旋挤压的活动特点。全新世以来,该断裂带的平均滑移速率为:水平位错1.93毫米/年,垂直位错0.82毫米/年。

| Abstract: | The Yumushan Eastern Marginal Fault Zone Lies the west margin of the ZhangyeMinle basin and in the central part of the Hexi corridor.It is a NNW---trending late Quaternary active fault zone and a high--angle,right--lateral compression fault zone based on the analysis of geological--landform feature.Since Holocene Epoch,the average slip rate of the horizontal and the vertical displacement on the fault zone are 1.93mm/a and 0.81mm/a. |

| Keywords: | Yumushan Active faeature Slip rate |
