| 摘 要： | 东昆中构造混杂岩带是经历了晚元古代、加里东末和晚海西期三次碰撞事件而形成的多旋回复合碰撞缝合带，通过对东昆中构造混杂岩带晚加里东期左旋斜冲韧性剪切变形的几何学、运动学及流变学特征的研究，探讨了其形成的构造背景，指出该期构造变形是东昆中加里东末碰撞事件的产物。

| Abstract: | The central eastern Kunlun tectonic melange belt is located in the ophiolite tectonic melange belt formed by the polycycle orogency of eastern Kunlun orogenic belt,which represents the convergence and collision of plates in Neoproterozioc,Late Caledonian and Late Herecynian.The characteristics of geometry,kinematics and rheology of the sinistral oblique thrust ductile shear deformation in late Caledonian are studied and its tectonic background is analysed.It is suggested that the sinistral oblique thrust should be resulted from the collision in late Caledonian in central eastern Kunlun orogenic zone. |
