卡拉盖雷铜钴金矿是那拉提构造带内发现的首例以Cu为主,伴生Mo,Co,Au,Pb,Zn的火山岩型热液矿床.矿区内出露的地层主要为石炭系下统大哈拉军山组火山岩地层,矿区岩浆岩主要有花岗闪长岩、闪长岩和辉绿岩脉.通过火山岩地层和侵入岩样品的地球化学分析,认为区内大哈拉军山组是一套由玄武岩、安山岩、英安岩、流纹岩组成的连续亚碱性的火山岩系列,且以钙碱性系列为主；矿区钾长花岗岩属于准铝质—过铝质岩类,碱性系列,花岗闪长岩和闪长岩属于准铝质—过铝质岩类,钙碱性—碱性系列,基性侵入岩属于弱碱性—碱性系列.稀土元素特征显示中酸性侵入岩可能属于地壳重熔型花岗岩；基性侵入岩与基性火山岩来源一致.%Kalagailei is the first volcanics-hosted hydrothermal ore deposit dominated by Cu with byproducts of Mo, Co, Au, Pb and Zn. in Nalati structure belt. In the mine area are mainly exposed volcan-ics of Lower Carboniferous Dahalajunshan formation. Magmatic rocks here are mainly granodiorite, dio-rite and diabase dykes. Dahalajunshan formation is made up of basalt, andesite, dacite and rhyolite. Geo-chemical analysis shows that the formation belongs to a sub-alkaline volcanic series but is dominated by calcium-alkaline series; moyite metaluminous-peraluminous rock, alkalic series; granodiorite and diorite metaluminous-peraluminous rock, calcic-alkalic to alkalic series; basic intrusive rock weak alkalic to alkalic series. Feature of REE indicates that moyite is derived from crust remelting and basic magmatic rock and basic volcanics are cognate.
