| 摘 要： | 滇西北鲁甸花岗岩可分为5个单元。归并为2个序列。早期序列-拉美荣序列由窝窝底，格庄，五点石3个单元组成，生成于早-中三叠世，为壳幔混源岩浆形成，属火山弧花岗岩，是金沙江结合带俯冲消减的产物，晚期序列-打米杵序列由阿竹生，哇甫莫2个单元组成，生成于晚三叠世，为壳源花岗岩，形成于同碰撞环境，是金沙江结合带碰撞造山的物质记录。

| Abstract: | The Ludian granite in northwest Yunnan can be divided into 5 units of 2 series. The Wowodi, Gezhuang and Wudianshi units of the earlier Lamerirong series were formed by crust and mantle magma in early middle Triassic. They belong to the volcanic are granite formed by the subduction of Jinshajiang conjunction zone. The Azhusheng and Wafumo units of the later Damichu series were formed by the crust derivation granite in late Triassic. They were formed in the collision orogeny environment of Jinshajiang conjunction zone. |
