| 摘 要： | 著名的东天山黄山—镜儿泉铜镍成矿带中有许多成因相似的铜镍矿床,本文在野外调查和镜下鉴定的基础上通过电子探针成分测试,对香山铜镍矿床矿石矿物成分做了详细研究,将矿石矿物划分为Fe-S系列、Fe-Cu-S系列、Fe-Co-Ni-S系列、Fe-Co-Ni-As系列、Fe-Co-Ni-As-S系列和碲化物。根据矿物共生组合特征,将成矿过程划分为岩浆熔离成矿期、岩浆热液成矿期和表生风化期;通过矿物成分晶体化学式计算,阐述了矿物的赋存状态和成因。香山岩体锆石U-Pb年龄(285±1.2)Ma髴,镍黄铁矿Re-Os等时线年龄(298±7.1)Ma1],成岩、成矿年龄具有一致性。

| Abstract: | The well-known Huangshan-Jing'erquan Cu-Ni metallogenic belt in East Tianshan Mountains has lots of genetically similar copper-nickel deposits.Based on field investigation,the authors made electron microprobe analysis of the components and carried out a detailed study of the mineral composition of the copper-nickel ore deposits.The ore minerals can be classified into Fe-S series,Fe-Cu-S series,Fe-Co-Ni-S series,Fe -Co -Ni -As series,Fe -Co -Ni -As -S series and telluride.According to characteristics of mine... |
