摘要:

纳日贡玛铜钼矿床是位于三江成矿带的大型铜(钼)矿床。虽然该矿床在找矿工作上取得重大突破,但关于矿床成矿模式的理论研究较少。在总结矿床地质特征的基础上,对矿区内花岗斑岩的矿物岩石化学成分、微量元素和稀土元素特征进行分析,测试包裹体均一温度、盐度、化学成分及C、H、O同位素组成,探讨其热液蚀变类型及分带特征。结果表明:该矿床为斑岩型铜钼矿床,其成矿物质主要来源于花岗斑岩体,成矿流体为岩浆水和大气降水组成的混合热液。在此基础上,提出了纳日贡玛铜钼矿床的成矿模式,利用Micromine软件建立了矿床三维立体模型,其成果为矿床成因的认识与找矿工作提供了参考。

Abstract:

Narigongma is a large Cu-Mo deposit found in the Sanjiang metallogenic belt.Although breakthrough has been made in the exploration work,few studies have been devoted to the theoretical research for the minera-lization.Based on the study of the geological characteristics of the Narigongma Cu-Mo deposit,the authors analyze the geochemical components of the ore-bearing rock,characteristics of trace elements and rare earth elements,measure the homogenization temperature,salinity,chemical composition,as well as ...

Key words: Narigongma Cu-Mo deposit, metallogenic model, porphyry Cu-Mo deposit, three dimensional deposit model, Sanjiang metallogenic belt
