| 摘 要： | 贵州省锦屏县八克金矿流体包裹体以原生包裹体为主,少量次生包裹体。包裹体大小在2-10μm之间,个别大于10μm;以含CO2三相包裹体为主,其次气液两相包裹体,少量纯CO2包裹体;成矿流体包裹体的均一温度集中在240℃-300℃,气液两相包裹体平均盐度4.29 wt%NaC l-6.51 wt%NaC l,密度为0.75 g/cm3-0.92 g/cm3,三相包裹体平均盐度:1.91 wt%NaC l-5.11 wt%NaC l,密度为0.62 g/cm3-0.97 g/cm3,得出结论是八克金矿属于低盐度低密度的中温矿床。

| Abstract: | Fluid inclusions from Bake gold deposit in Jinping County,Guizhou Province,are primary inclusions in the main,a small amount of secondary inclusions.The sizes of inclusions are between 2 to 10 microns,and the individual is greater than 10 microns.Three-phase inclusions containing CO2 account for the main,followed by gas-liquid two-phase inclusions,a small amount of pure CO2 inclusions.The ore-forming fluid homogenization temperature concentrated in 240 ℃-300 ℃,The salinities of gas-liquid two-phase inclusions range from 2.56 wt%NaCl to 9.47 wt%NaCl,and the densities from 0.75 g/cm^3 to 0.92 g/cm^3;The salinities of three-phase inclusions containing CO2 range from 0.21 wt%NaCl to17.27 wt%NaCl,and the densities from 0.62 g/cm^3 to 0.97 g/cm^3.To sum up： Bake gold deposit is a low density,low-salinity and middle-range temperature deposits |
