| 摘 要： | 通过矿床流体包裹体岩相学、显微测温学和激光拉曼光谱成分分析，研究成矿流体性质，探讨了矿床成因类型.研究结果表明，流体包裹体以气液两相包裹体为主，少量含CO2三相、含子矿物三相和纯气相包裹体等.成矿流体均一温度为320~360℃，盐度为19.2%~21.8%，密度为0.73~0.90 g/cm3，估算成矿压力为92.1~129.1 MPa，成矿深度为3.07~4.3km.成矿流体气相成分以H2O为主，其次为CO2、CH4和N2，微量的C6H6、C2H6和C3H8等，总体属H2O-CO2-NaCl体系.成矿流体是一种不混溶流体，主要来源于深部岩浆，并可能有幔源组分参与.金主要是以金氯配合物的形式迁移.矿床的地质-地球化学特征与隐爆角砾岩型金矿类似，应属隐爆角砾岩型金矿床.

| Abstract: | On the basis of the results from the inclusion petrofacies,micro-thermometry and laser Raman spectrographic analysis,the ore-forming fluid characters are systematically studied,and the genesis of the Hulalin gold deposit is discussed.The results show that these inclusions consist of mainly gas-liquid two-phase,with minor CO2-bearing three-phase,daughter mineral-bearing three-phase and pure CO2 types.The homogenization temperature of ore-forming fluids ranges from 320 to 360 ℃,with salinity（NaCl）of 19.2%-21.8%,and density of 0.73-0.90 g/cm3.The estimated mineralizing pressure is between 92.1 and 129.1 MPa,with mineralizing depth of 3.07-4.3 km.The gas composition of ore-forming fluids is mainly H2O,followed by CO2,CH4and N2,with less C6H6,C2H6 and C3H8,belonging to H2O-CO2-NaCl system.The ore-forming fluids are unmixed,mainly from the deep magmas and maybe joined with mantle components.The gold is transferred mainly in the form of gold-chlorine complex.The geological and geochemical features of the deposit are similar to those of cryptoexplosion breccia gold deposits.So it can be assigned to the cryptoexplosion breccia type. |
