| 中文摘要: |
| 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。 |
| 英文摘要: |
| Kalagailei is the first volcanics-hosted hydrothermal ore deposit dominated by Cu with by-products of Mo, Co, Au, Pb and Zn. in Nalati structure belt. In the mine area are mainly exposed volcanics of Lower Carboniferous Dahalajunshan formation. Magmatic rocks here are mainly granodiorite, diorite and diabase dykes. Dahalajunshan formation is made up of basalt, andesite, dacite and rhyolite. Geochemical 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. |
