摘要 通过对流体包裹体镜下观察、温度和成分测定,获取贵州省天柱县地豆冲金矿石英包裹体以原生液体包裹体为主,大小3-16μm,气液比集中于5%-15%;流体包裹体的均一温度在142.3-307.1℃;流体盐度为2.74-10.11 wt%NaCl,密度为0.81-0.93 g/cm3,气相成分以H2O为主,含少量CO2、N2、CH4;成矿压力为265.25-451.67 bar,成矿深度为1001.43-1705.25 m.该矿床属成矿压力低的浅成中低温热液矿床,其成矿流体具低盐度、低密度的特征。 According to observation of fluid inclusions under microscope and measurement of temperature and salinity,fluid inclusions from Didouchong gold deposit in Tianzhu County,Guizhou Province,are primary liquid inclusions in the main,sizes are between 3 to 16 microns,gas-liquid is range of 10%-15% mainly.The homogenization temperature of fluid inclusions range of 142.3-307.1 ℃.The fluid salinity range of 2.74-10.11 wt%NaCl,density range of 0.81-0.93g/cm3,gas composition is H2O in the main,containing a small amount of CO2,N2,CH4.Ore-forming pressure rang of 265.25-451.67 bar,depth range of 1001.43-1705.25 m.In summary,Didouchong gold deposit is a shallow-depth,small-pressure and medium-low temperature hydrothermal deposit,ore-forming fluid with characteristics of low-salinity and low-density.
