摘要
辉发河断裂带先期以继承槽台边界断裂为特征。后期以差异性平移运动为主。依据构造地质特征和运动形式,该断裂带可分为四个发展阶段。该断裂带左旋平移运动不存在两侧整体相对大规模平移,主要表现为一系列补偿性构造,其结果造成地壳缩短。左旋平移运动距离应与地壳缩短量相当,推测平移距离为30～40km。
At first, the Huifahe fault belts were characterized by inheriting the fractures between the geosyncline and platform and then, the different strike slip movements became dominant. According to the tectonic characteristics, the Huifahe fault belt can be divided into four stages in evolution. This fault belt displays a sinistral strike-slip movement. The strike-slip distances in both sides are short, exhibiting mainly a series of off-set structures. The distance of the sinistral strike-slip movement is almost the same as that of shortening of the earth crust. The strike-slip distance infferred is 30-40km.
