中条山地区八一铜矿床中白钨矿的发现及其找矿意义

The Discovery of Scheelite from the Copper Deposit in the Zhongtiaoshan Area and Its Implication for Tungsten Ore Prospecting in North China

  • 摘要: 中条山地区是我国重要铜矿基地之一,虽然区域资料中有钨的化探异常,但以往没有发现有价值的钨矿。文章在八一铜矿研究过程中,通过X射线荧光光谱野外快速分析仪检测、荧光灯检查、光薄片鉴定和电子探针分析,查定出含铜矿脉中赋存白钨矿矿物,其共伴生矿物主要是黄铜矿、闪锌矿和方铅矿,脉石矿物以方解石、白云石和石英为主。通过对白钨矿矿物、金属硫化物、主要脉石矿物的电子探针分析,结合碳同位素组成,初步判断八一铜矿为岩浆热液成因。八一铜矿脉中白钨矿的发现,不但对深入研究我国钨矿的区域成矿规律具有重要意义,也有助于丰富中条山地区的矿床学研究内容,拓展找矿思路。

     

    Abstract: In the past, the Zhongtiaoshan area was one of the main places to find copper deposits in China. Although there was a tungsten anomaly in geochemical exploration, no tungsten ore had been discovered, and the tungsten ore resource has not drawn much attention. During the study of the Bayi copper deposit, scheelite was discovered and confirmed in copper-bearing veins by field fast X-ray Fluorescence Spectrometry (XRF) analyzer, fluorescent lamp, optical microscope and electron probe. The associated minerals of scheelite include chalcopyrite, sphalerite and galenite, and the gangue minerals are mainly composed of calcite, dolomite and quartz. The genesis of the Bayi copper deposit was considered preliminary as a mantle-derived magmatic hydrothermal fluid when examined by electron probe analysis of the scheelite, sulfides and gangue minerals and C stable isotopic compositions. The discovery of scheelite in the Bayi copper deposit veins is not only important for the further study of regional tungsten metallogenic regularity in China, but also helpful for tungsten prospecting in the Zhongtiaoshan area.
