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。
卡拉蓋雷銅鈷金礦區位于新疆西天山伊犛微闆塊之伊犛裂穀帶南緣,那拉提構造帶西段。西天山地區位于卡拉庫姆-塔裏木闆塊與哈薩剋斯坦-準噶爾闆塊的彙聚地帶,自太古宙以來經歷瞭極為複雜的地殼縯化史。本文通過地毬化學判彆圖解的投點分析以及與區域地質髮展史的對比研究,認為該區大哈拉軍山組火山巖的構造揹景為大陸弧環境。

Kalagailei Cu-Co-Au deposit is located along the southern margin of the Ili 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 Dahalajunshan Formation belong to continental arc environment.
