| 中文摘要:西昆仑造山带花岗岩存在６个大的侵入旋回和９个侵入期，分别形成于洋脊环境、火山弧环境、碰撞后隆起环境和造山晚期相对拉张环境。前３种环境形成的花岗岩记录了洋盆形成→洋壳俯冲→陆－陆碰撞过程，而后两者则历程地反映了碰撞期后岩石圈构造演化的深部机制。 |

| Tectonic Environments of Granitoids in the West Kunlun Orogenic Belt |

| Abstract:There are six intrusive cycles and nine intrusive periods of granitoids in west Kunlun orogenic belt.The granitoids were formed in ocean ridge,volcanic arc,syn-collision,post-collision uplift and late orogenic environments respectively.The first three granitoids record the processes of ocean basin formation→ocean crust subduction→continent collision whereas the last two granitoids give expressin to the deep mechanism of lithospheric evolution in post-collision period. |
