【摘要】 辽宁东五家子金矿的矿脉由蚀变岩和石英脉透镜体构成,可采矿体均为硫化物石英脉型。工业矿脉中,石英为烟灰色,发育他形、半自形的细粒黄铁矿等硫化物,有较大规模的矿体。矿化脉中,石英为乳白色,发育粗粒、自形的浅色黄铁矿,无可采矿体。在工业矿脉、次要矿脉、矿化脉的蚀变岩和石英脉样品中,Au,Hg与其他元素的相关性有明显区别。用石英脉样品的As-Ni-Ba图解和蚀变岩样品的Au-Ag-Ba图解预测,矿区外围的西沟1号脉和西沟3号脉属于工业矿脉。更多还原

【Abstract】 The gold lodes in the Dongwujiazi Gold deposit consist of altered rocks and quartz lenses with minable ore bodies being quartz-sulphide veins.In industrial lodes with large ore bodies,quartz is smoky-grey,and pyrite is fine,xenomorphic and hypidiomorphic.The mineralized lodes with milky quartz and coarse,pale and idiomorphic pyrite do not contain minable ore bodies.The relationship of Au and Hg with other elements shows great differences among industrial,subeconomic and mineralized lodes.Using the As-Ni-Ba diagram of quartz veins and Au-Ag-Ba diagram of the altered rocks,No.1 and No.3 lodes in the Xigou area outside the mine are suggested to be of industrial significance.更多还原
