摘　　要：对毛毛山断裂带断层岩进行了宏观及微观的观察和分析，特别是对断层岩中石英颗粒的形貌特征、溶蚀类型及断层岩的组分进行了研究。结果表明该断裂是一条具有多期活动的全新世活动断裂．滑动性质以粘滑为主，断裂的东段较西段更为明显。In this paper,the fault rock of Maomao mountain fault zone was inspected and analyzedmacroscopically and microscopically, particularly the shape feature and dissolution type ofquartz grain and components of .fault rock were studied. It is indicated that this fault is an active fault in Holocene with multiple activities,and mainly on stick-slip formation. The eastpart of the fault is more active than the west one.
