摘　　要：朱溪超大型钨(铜)矿床位于钦—杭结合带江西段,电子探针主量元素测试结果表明,该矿床辉石属于透辉石—钙铁辉石系列,主要为透辉石(均值57.95%),钙铁辉石次之(均值35.47%),以及少量的钙锰辉石(均值6.57%),符山石矿物中F元素含量(均值1.50%)较高。推测朱溪钨(铜)矿床中矽卡岩从深部到浅部流体逐渐从氧化向还原演化,早期矽卡岩阶段—晚期矽卡岩阶段流体挥发性成分相对充足,为成矿作用提供了有利的流体条件。Zhuxi super-large scale tungsten(copper)deposit is located in the Jiangxi Section of Qin Hang junction zone.The results of electron microprobe analysis of major elements show that the pyroxene of Zhuxi deposit belongs to Diopside-Hedenbergite series,mainly diopside(average 57.95%),followed by Hedenbergite(average 35.47%),and a small amount of Johannsenite(average 6.57%).The content of F element in Vesuvianite mineral(average 1.50%)is high.It is speculated that the fluid of skarn in Zhuxi tungsten(copper)deposit gradually evolved from oxidation to reduction from deep to shallow,and the volatile components of fluid from early skarn stage to late skarn stage are relatively sufficient,which provides favorable fluid conditions for mineralization.
