摘要
大渡河大岗山水电站坝区断裂的发育和空间分布与辉绿岩脉关系密切,规模小,优势产状为南北走向、西倾、中-陡倾角,以脆性变形为主。通过石英形貌分析结果和电子自旋共振测年说明研究区内的断裂的主要活动时期是早更新世-晚上新世。
The faults in dam area of Dagang Mountains on Dadu River had intimate relationship with diabase dike about development and space-distribution. The characteristics of the faults are small-scale, west dip direction and medium to steep dip angle. The study about topographical features and quartz pattern proved that the activity age of the faults was early Pleistocene epoch to late Pliocene.
