摘要
鸭绿江断裂带为郯庐断裂带羽状分支的一部分,其动力学机制为燕山期太平洋板块与欧亚板块碰撞.由于剪切作用形成一系列北东向左旋运动为主的壳断裂,切割深度约4 km,最大左行平移距离超过20 km.主断裂两侧地质构造特征可以对比.
The Yalujiang fault zone is a branch the Tan-Lu giant fault zone, which crosses eastern China. Its dynamic mechanism is the collision between the Pacific plate and Eurasian plate during Yanshanian period. The sheafing movement forms a series of NE-trending sinistral crustal fractures, in depth about 4 km, with maximal left displacement more than 20km. The geological structural characteristics on both sides of the major fault are comparable.
