摘　　要：运用显微镜和激光拉曼技术对小西南岔富金铜矿床北山矿段流体包裹体内的子晶矿物进行了鉴定。结果表明,其子晶矿物有硬石膏、石盐、钾盐以及黄铜矿等,这种特征反映该矿床的含矿流体为高盐、高氧化流体和还原流体,为进一步研究该矿床流体性质和矿床的成因提供了重要依据。Daughter minerals in fluid inclusions from sulphide - quartz in north mining area of Xiao- xinancha gold-rich copper deposit（Jilin Province）, were studied by microscope and laser Raman technique. It is proved that daughter minerals in different fluid inclusions include anhydrite, halite, sylvine and chalcopyrite. Characteristics of both these fluid inclusions and their daughter minerals indicate that the Ore-forming fluid is of high salinity, oxidation and deoxidization. The conclusion also gives some important clues for further study on both ore-forming fluid and genesis of the deposit.
