| 摘 要： | 大凉山断裂带呈近南北向或北北西展布于安宁河、则木河断裂东侧的大凉山腹地，是一条连接鲜水河、小江断裂的贯通性全新世活动断裂，全长约280km。航、卫片解译及野外实地考察结果表明，大凉山断裂带由海棠-越西、普雄河、布拖及交际河四条次级断裂呈羽列组合而成，晚第四纪以来的平均左旋滑动速率在3mm／a左右。

| Abstract: | The Daliang Mountain fault zone is spread out in near SN or NNW in Daliang Mountain hinterland east of the Anning River and Zemu River faults and is through Holocene active fault connecting Xianshui River and Xiaojiang faults,with total length of 280 km.The interpretation of aerophotos and satellite photographs and the results of field exploration show that the Daliang Mountain fault zone is consisted of the four secondary faults like feather,Haitang- Yuexi ,Puxiong River,Butuo River and Jiaoji River faults, and its average left-lateral slip motion rate since late Quaternary period is about 3 mm/a. |
