| 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。

| Abstract: | 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 H2O 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/cm3.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. |
