江西朱溪钨铜矿是近年新发现的具有超大型规模前景的钨铜矿床,本文采集了大量朱溪钨铜矿床样品,用偏振激发能量色散X射线荧光光谱、电感耦合等离子体质谱/光谱等技术分析主量和微量元素含量,根据各元素的含量水平以10种主要成矿元素(W、Sn、Bi、Mo、Pb、Zn、Cu、As、Sb、Ag)作为分析研究区原生晕地球化学特征的指示元素。结果表明,Cu、Zn、Ag、Pb和W、Bi、Sn、Mo的元素共生组合十分明显,同时W与Cu也有相关性,富集W的部位同样也富集了Cu。成矿元素在空间上的分布特征为:1同一剖面上越往北西方向,W为主的高温元素更为富集;平面上越往南西方向,W为主的高温元素更为富集;越往深部,W为主的高温元素更为富集。2Cu为主的中温元素富集深度比W为主的高温元素富集深度浅。研究认为,铜矿富集部位在中、深部(-1400~-1500 m),钨矿富集部位在深部(-1400~-1900 m),Ag、As、Sb等低温元素的富集部位更靠近地表(-1100~-1200 m)。这种剖面线上和平面上的原生晕地球化学特征为该矿床进一步勘探工作与成矿预测提供了理论依据。
The ZhuXi tungsten-copper deposit in Jiangxi province is a tungsten-copper deposit newly discovered in recent years with very large-scale prospect. In this paper, a large number of samples of ZhuXi tungsten-copper deposit are collected and analyzed by polarization excitation energy dispersive X-ray fluorescence spectrometry, inductively coupled plasma mass spectrometry / (W, Sn, Bi, Mo, Pb, Zn, Cu, As, Sb, Ag) were analyzed according to the content of each element in order to analyze the main and trace element contents. Halo geochemical characteristics of the indicator element. The results show that the elemental symbiosis of Cu, Zn, Ag, Pb and W, Bi, Sn and Mo is very obvious. At the same time, the correlation between W and Cu is also obvious. The distribution characteristics of the ore-forming elements in space are as follows: 1 The more W-dominant high-temperature elements in the same section are more enriched; the more W-oriented high-temperature elements in the plane are more enriched; , W-based high-temperature elements are more concentrated. 2Cu-based temperature element enrichment depth W-based high-temperature element enrichment depth shallow. The study shows that the enrichment sites of copper deposits in the deep (-1400 ~ -1500 m), tungsten enrichment sites in the deep (-1400 ~ -1900 m), Ag, As, Sb and other elements of low temperature enrichment sites more Close to the surface (-1100 ~ -1200 m). The primary halo geochemistry on the profile line and in the plane provides a theoretical basis for further exploration and mineralization prediction of this deposit.
