摘要:
继江西省武宁县大湖塘地区发现并查明了世界最大的钨矿之后 ,近年来在江西省浮梁县朱溪地区又发现了具有世界级资源潜力的钨铜矿.通过分析浮梁县朱溪钨铜矿床隐伏成矿花岗岩的区域构造背景、岩石学特征、围岩蚀变、稀土与微量元素地球化学特征等 ,探讨花岗岩的成因及其与成矿的关系.研究表明 ,该矿床的形成与朱溪花岗岩具有密切关系 ,朱溪花岗岩既不同于S型花岗岩 ,也不同于I型花岗岩 ,这种壳幔混杂与地层叠覆—壳层同熔型岩浆系列的过渡成就了朱溪超大型矿床.

Abstract:
Recently ,some tungsten copper deposits with world class resource potential have been dis-covered in Zhuxi area ,Fuliang County ,Jiangxi Province after the world's largest tungsten deposit were found in Dahutang area ,Wuning County ,Jiangxi Province .According to the study on regional tectonic setting ,petrological characteristics ,country rock alteration ,geochemical characteristics of rare earth and trace elements of concealed ore-forming granites in Zhuxi tungsten-copper deposit ,Fuliang County ,the genesis of granites and relationship of mineralization are discussed in this paper .The result shows that the origin of Zhuxi tungsten-copper deposit is associated with granites which are different from S-type and I-type granite .It shows that the transition of crust mantle mixing and stratigraphic overlap ,crust strati-graphic syntectic magma series has an important role in the formation of Zhuxi super-large deposit .
