摘　　要：通过矿床流体包裹体测量,晴隆锑矿成矿温度在125℃~200℃、流体盐度为(0.35~2.24)wt%NaCleq、流体密度为0.88g/cm^3~0.95g/cm^3,成矿流体属Ca^(2+)-Na^+-Cl~﹣-F~﹣型体系。流体气相组分最主要为H_2O等。晴隆锑矿成矿类型为火山沉积—改造型层控矿床。Measurement of fluid inclusions in ore deposit has indicated that the ore-forming temperature of Qinglong antimony deposit is 125℃/200℃,the salinity of fluid is(0.35~2.24)wt%NaCleq,the density changes between 0.88 g/cm^3 and 0.95 g/cm^3,and the ore-forming fluid belongs to Ca^2+-Na^+-Cl^--F-type system.The main component of fluid vapor is H2O etc.The genetic type of Qinglong antimony deposit attributes to volcanic sedimentary-reformed stratabound deposit.
