在仙女山-九畹溪断裂带野外地质调查的基础上采集12件断层泥样品,并对样品进行石英碎砾提取和扫描电镜微形貌观察.结果表明,仙女山断裂为一条以粘滑为主的活动断裂,最近一次较大规模的运动发生在中-晚更新世;九畹溪断裂带具有多期活动迹象,早期活动强于晚期,近期强烈活动在上新世至中更新世,为一条以粘滑运动为主的活动断裂.仙女山-九畹溪断裂带所构成的V型断裂组合表现为以仙女山断裂带为主导的构造格局.“,”On the basis of extensive field geological survey of the Xiannüshan-Jiuwanxi fault,we collect 12 gouge samples,extract the quartz and observe their micro-morphology by SEM.The results show that the Xiannüshan fault is an active fault essentially characterized by stick-slip,and that recent large-scale movement happened in the middle-late Pleistocene period.The Jiuwanxi fault is also an active fault essentially characterized by stick-slip with multi-periodic activities,with early activities much stronger than late ones.Its last activity has taken place during the Pliocene and the middle Pleistocene period.Furthermore,the “V” glyph fracture combination formed by the Xiannüishan-Jiuwanxi fault presents a tectonic pattern which is dominated by the Xiannüshan fault.
