| 摘 要： | 对比利牛斯等造山带典型弧形构造的分析表明,弧形构造是造山带尤其是板内碰撞造山带的普遍特征,可分为挤压逆冲-推覆主动型构造和推覆-滑覆被动型弧形构造。西昆仑—帕米尔是与比利牛斯Basque弧在空间形态、运动学及动力学特征等方面一致的挤压逆冲-推覆主动型弧形构造,推测该弧中部存在一巨大的底部低角度逆掩断层并由根部带向北延伸达100多公里,康西瓦断裂(基底缝合带)可能是主根部逆冲断层带。

| Abstract: | By the analysis of typical arc tectonics in orogenic belts such as Pyrenees, this paper concluded that arc tectonics are the general characteristics of orogenic belts, especially intracontinental orogenic belts, which could be divided into two types: thrust -nappe active type and thrust - sliding positive type. West Kunlun-Pamir mountains are the arc tectonics of thrust-nappe active type compared with Basque Arc in Pyrenees in the characteristics of spatial shapes, kinematics and geodynamics and considered that there is a large lower angle thrust fault extending 100km to the north from the root belt along the middle parts of the arc. The south boundary faults of Center Kunlun is the possible root thrusting belts. |
