绪言我国钨矿资源以对脉状黑钨矿床的研究、开发、利用较为详细。这类矿床大多具有多期、多阶段的成矿特点,因而矿床中伴生组分复杂,可供综合利用。作者以瑶岗仙脉钨矿床为研究对象,通过矿床地质调查、采集样品、单矿物分离与提纯,利用显微镜(实体、偏光、反光)、化学分析、原子吸收光谱分析、扫描电镜及电子探针等手段,重点对矿床中的工业矿物(黑钨矿、黄铜矿、黝锡矿、锡石、毒砂)进行单矿物研究,较系统地查明了矿床中主要伴生组分—金、银、铌、钽、钪等的含量、分布和赋存状态,探讨了钨—锡—硫化物(铜、铅、锌)多金属矿床伴生组分的分布规律及矿床形成温度与成矿作用方式。
Introduction Tungsten ore resources in China to the vein of tungsten ore research, development, use more detailed. Most of these deposits have multi-stage and multi-stage metallogenic characteristics, so the associated components in the deposit are complex and can be used comprehensively. The author takes the Yao-gang Xian-Mai tungsten deposit as the research object. Through the geological survey of the deposit, the samples are collected and the single mineral is separated and purified. The microstructure (polarization, reflectance), chemical analysis, atomic absorption spectrometry, SEM and electron probe And other means, focusing on the mineral deposits in the industrial minerals (wolframite, chalcopyrite, stannous tin, cassiterite, arsenopyrite) single mineral study, more systematically identified the main associated components of the deposit - gold, silver , Niobium, tantalum, scandium, etc. The distribution of accompanying components and the formation temperature and metallogenic mode of tungsten-tin-sulfide (Cu, Pb, Zn) polymetallic deposits are discussed.
