| 摘 要： | 经过对则木河活动断裂带的 1∶5万地质填图及重点地段开挖槽探和剥土 ,采集了年代样品与构造岩薄片样 ,实测断错地貌 ,同时进行了研究区的航、卫片解译 ,并对前人所作工作成果进行了分析。在此基础上我们对该区活动断裂带的平面展布、几何结构、不同时期的活动习性以及它的形成机制、运动形式等方面作了深入的探讨 ,包括全新世断裂的研究和它的未来强震危险性估价。本成果的整理发表 ,对开发西昌地区 ,振兴西昌经济 ,促进川、滇两省边界地区经济的发展提供了有利条件 ,同时也可作为有关方面的参考。

| Abstract: | The geologic mapping and comprehensive analysis on the active faults of Zemuhe provides us with the results from the works such as trenching,samples age ,tectonic analysis to rock wafer,geomorphologic mapping of fault heave ,aerial photographic interpretation,satellite photographic interpretation.Basing on these results above and works down by other persons before,we discuss the plane distribution,the geometric tectonic,the faults activities and its forming mechanics on the active fault of Zemuhe .The seismic activities of the fault in holocene epoch and hazard analysis about future large earthquakes are also included at the same time.We think that these papers will be good for the economical development of Xuchuan region. |
