| 摘 要： | 大蒲河地区地处龙岗地块北缘活动带内，发育四条规模较大的韧性剪切带。韧性剪切带总体呈北西向平行带状展布，分别形成于不同时期，发育在不同的地质体中。其运动学特征以左旋斜滑为主，兼有左旋斜冲和右旋斜冲特征，均为地壳中部层次绿片岩相条件下动力变质作用的产物。

| Abstract: | The Dapucahe area is located in the mobile belt of northern margin of the Longgang area, Jilin province in which four large scale ductile shear zones are developed. They exhibit a parallel zonal arrangement with a general NW strike, and were formed in different stages and occurred in geologic bodies. From kinematic characteristics, the left-lateral oblique-slip is primary; left or ritht oblique thrust is secondary, resulting from the dynamic metamorphism with codition of greenschist facies in the central part of Earth's crust. |
