摘　　要：通过对新疆加曼特金矿床矿脉中石英、闪锌矿、方解石内发育的流体包裹体进行显微测温分析,计算得出流体的盐度和密度;同时采用激光拉曼光谱对单个流体包裹体的成分进行分析。结果表明,加曼特金矿流体包裹体激光拉曼图谱上显示仅有H2O峰,成矿流体属NaCl-H2O体系;均一温度主要集中在180～260℃,盐度在0.17%～12.52%,密度为0.49～0.97 g/cm3,初步认为该矿床应属于浅成低温热液型矿床,成矿流体显示低温、低盐度和低密度的性质。The salinity and density of fluid inclusions in quartz, sphalerite and calcite hosted in gold-bearing veinlets of Jianante gold deposit, Xinjiang, were studied by micro temperature measurement measurement. Also, the components in fluid inclusions were studied by using Laser Raman Spectrometry. The results indicate that only a H20 peak was shown on the Laser Raman spectrum atlas for all fluid inclusions, which was attributed to the NaCl-H2O system. Homogeneous temperatures ranged from 180℃ to 260℃ with salinities in the range of 0.17% - 12.52% and densities in the range of 0.49 - 0. 97 g/cm^3. This indicates that ore-forming fluids are characterized by low temperature, low salinity and low density. The conclusion is that the Jiamante Au deposit is an epithermal deposit.
