摘　　要：卡拉盖雷铜钴金矿区位于新疆西天山伊犁微板块之伊犁裂谷带南缘,那拉提构造带西段。西天山地区位于卡拉库姆-塔里木板块与哈萨克斯坦-准噶尔板块的汇聚地带,自太古宙以来经历了极为复杂的地壳演化史。本文通过地球化学判别图解的投点分析以及与区域地质发展史的对比研究,认为该区大哈拉军山组火山岩的构造背景为大陆弧环境。Kalagailei Cu-Co-Au deposit is located along the southern margin of the Ill rift belt in the Ili mi- cro-plate in Western Tianshan Mountain, western part of Nalati tectonic zone, Xinjiang. And Western Tianshan Mountain is situated in the convergence zone of Karakum-Tarim plate and Kazakhstan-Junggar plate. It has a very complex history of crustal evolution since Archean. Through the analysis of geochemical discrimination dia- gram, and the comparison with regional geological development history, the authors suggest that the tectonic set- ting of the igneous rocks in the Dahalaiunshan Formation belon~ to continental arc environment.
