With the methods of investigation which includes physiognomy,quaternary,tectonic and earthquake,the quartz shape scanning in the fracture zone and ESR dating,we draw a conclusion that Meigu River fracture zone is composed of three imbricate faults,which has not been active since the middle Pleistocene,and it is not an.
通过地貌、第四系、地质构造及地震等野外地质调查和断裂带石英形貌扫描、ESR测年等方法综合研究表明,美姑河断裂带是由3条断层组成的叠瓦断层带,在中更新世(Q2)以来已不具活动性,不属于活动断层,亦不具有诱发地震的能力,因此断裂带活动性对工程建设影响不大。
补充资料：C14测年
含c物质的c14含量在c元素中所含的比例几乎是保持恒定的，如果含c物质一旦停止与大气的交换关系，则该物质的c14含量不在得到新的补充，而原有的c14按照衰变规律减少，每隔5730年减少一半，因此只要测出含c物质中c14的减少的程度，就可以计算出它停止与大气进行交换的年代，这就是c14测年的原理。
