摘　　要：新疆阿尔泰可可托海3号伟晶岩脉具有非常完美的结构分带,从边部到核心可以划分出9个共生结构带.本文主要利用前人资料,从该伟晶岩脉的主元素、造岩矿物以及包裹体等角度对各结构带进行了研究,探讨了稀土元素在各带中的分布模式以及演化特征,并对3号岩脉的岩浆～岩浆热液演化阶段和地球化学阶段的划分作了修改.The Koktokay No. 3 granitic pegmatite dyke, Altai area of Xinjiang is characterized with a series of developed zones of mineral assemblages. From the edge to the core of the pegmatite dyke, 9 zones of paragenetic mineral assemblages were divided. This paper has discussed the characteristics of major elements, rock -forming minerals and fluid inclusions based on the predecessors date. It deal with the distribution patterns and evolution characteristics of REE of the various zones of paragenetic mineral, assemblages in the pegmatite dyke and has slightly modified the classification of the magma - magmatic hydrothermal fluid evolution stages for the No. 3 Koktokay granitic pegmatite dyke.
