| 摘 要： | 根据采集的天然断层泥样品，对西秦岭北缘活动断裂带东段的断层泥首次进行了粒度分布和显微构造特征的实验研究。研究结果表明，该断裂带以粘滑运动为主，兼有蠕滑活动，并具张性扭动特征。

| Abstract: | The grain size distribution and microstructure characters of fault gouge in the east section of northern edge of western Mt. Qinling are studied for the first time based on the collected samples of natural fault gouge. The results show that the fracture zone takes stick-slip movement as the dominant factor and has creep--slip and extendWeshear features at the same time. |
