| 摘 要： | 笔者利用解析构造学方法,初步确定了本区的构造序列。它反映了从下部构造层次到上部构造层次的系统变化,从早期的层内固态流变经压扁作用和弯曲作用到后期的剪切破裂变形过程中岩石韧性递减的系统演变。由于岩浆侵入而使其间增加了一个韧性再增强的变形期。

| Abstract: | A tectonic sequence in this area has been outlined on the basis of analytical tectonics. The sequence reflects a systematic change from the lower tectonic level to the upper one. The deformation mechanism also indicates a systematic evolution from the ductile flow through flattening, buckling to shear fracturing corresponding with the progressive decrease of rock ductility. There is an interlude of ductility increase caused by the intrusion of magma. |
