| 摘 要： | 东昆仑中部构造混杂岩带是经历了新元古代、加里东末期和晚海西期3次碰撞事件而形成的多旋回复合的碰撞缝合带。通过对东昆中构造混杂岩带晚海西期右行走滑韧性剪切变形的几何学、运动学及流变学特征的研究，探讨了其形成的动力学背景，指出东昆中晚海西期的碰撞缝合带是不同陆块间斜向碰撞形成的转换挤压带。

| Abstract: | The central East Kunlun tectonic Melange belt is a polycyclic composite collisional suture zone which was formed through the neoproterozoic,terminal Caledonian and late hercynian collisional events.The geometric,kinematic and rheological characteristics of the right-lateral stride-slip ductile shear deformation of the tectonic melange belt in the late hercynian are discussed and the dynamics background of its formation is also analyzed.It is suggested that the late hercynian central East Kunlun collisional suture zone is a transpression zone formed by oblique collisions of defferent continental blocks. |

| Keywords: | Kunlun melange belt ductile shear transpression zone late hercynian |
