对赋存于南秦岭泥盆系浅变质碎屑岩中的陕西太白金矿、凤县八卦庙金矿主成矿阶段的石英和含铁白云石中的流体包裹体进行研究 ,发现局部富含高盐度、含子矿物的流体包裹体 ,通过光学显微镜、电子探针 (EPMA)、扫描电镜 /能谱(SEM/EDS)发现子矿物主要为黄铁矿、铁白云石、石盐、毒砂及一些成分复杂的子矿物。认为矿床成矿流体具复杂的物理化学条件 ,不同于一般的热液金矿床。结合矿床形成的大地构造位置分析、主成矿阶段矿物组成特点、热液成因金属硫化物中高PGE含量特点、矿石中碳酸盐矿物中稀土元素配分曲线、矿石中碳酸盐矿物碳同位素组成特征等得出成矿流体具深源特征
The fluid inclusions in the quartz and iron-bearing dolomites in the main mineralization stage of the Taibai gold deposit in Shanxi Devonian metamorphic clastic rocks in the southern Qinling Mountains and the Bajiaamiao gold deposit in Fengxian County were studied. It was found that the local enrichment High-salinity, sub-mineral fluid inclusions, sub-minerals are mainly pyrite, iron dolomite, stone salt, poisoned by light microscopy, electron probe (EPMA), scanning electron microscopy / energy dispersive spectroscopy (SEM / EDS) Sand and some complex sub-minerals. It is considered that the ore-forming fluid has complicated physical and chemical conditions, different from the general hydrothermal gold deposit. Based on the geotectonic location analysis of the deposit, the characteristics of mineral composition in the main metallogenic stage, the characteristics of high PGE content in hydrothermal metallogenic sulfide, the distribution pattern of rare earth elements in carbonate minerals and the carbon isotopic composition of carbonate minerals in ore Derived fluid-forming fluid with deep source characteristics
