| 摘 要： | 德格—中甸微板块是在晚二叠世初随甘孜—理塘洋的产生而从扬子板块西缘分离出来的。在三叠纪时期受金沙江缝合带与甘孜—理塘缝合带构造作用的相互影响，其沉积构造性质也由被动边缘盆地演化为活动边缘盆地，同时分裂为白玉—义敦前陆盆地，昌台—乡城岛弧带、玉隆—稻城弧前盆地。

| Abstract: | Dg Zhongdian microplate was split off from the western margin of the Yangtze plate as the Garz Litang ocean opened in the late Permian.In the Triassic, the sedimentary structural zones developed from passive margin basin to active margin basin as a result of the influence of the Jinshajiang suture zone and Garz Litang suture zone,and split apart into the Baiyu Yidun foreland basin,Chomta Xiangcheng island arc zone and Yulong Daocheng fore arc basin. |

| Keywords: | passive margin active margin foreland basin island arc zone forearc basin |
