摘　　要：【目的】研究水晶中包裹体类型及其成分特征,为指示水晶成因提供指示意义【方法】利用电子探针、激光拉曼光谱等有效确定水晶中包裹体的类型及成分特征。【结果】伟晶岩型、矽卡岩型、热液型和变质型成因水晶中固体包裹体以金红石、阳起石、电气石、石榴石、方解石、绿泥石等为主;流体包裹体类型有气相包裹体、气液两相包裹体、富CO_(2)三相包裹体和含子矿物包裹体;均一温度变化范围在100~600℃,盐度变化范围在0~16 wt%,气液比变化范围在10%~60%。【结论】水晶中的包裹体可以反映水晶形成过程中地质流体的物化条件,指示矿床成矿物质的来源和演化规律,为矿床的成因机制提供重要信息。[Purposes]This paper aims to study the types of inclusions and their compositional characteristics in crystals,and to provide reference significance for indicating the genesis of crystals.[Methods]The use of electron microprobe and laser Raman spectroscopy can effectively determine the type and compositional characteristics of inclusions in crystals.[Findings]Solid inclusions in pegmatitic,skarn,hydrothermal,and metamorphic crystals are dominated by rutile,actinolite,tourmaline,garnet,calcite,chlorite,etc.Fluid inclusions include gas-phase inclusions,gas-liquid two-phase inclusions,CO_(2)-enriched three-phase inclusions,and inclusions of daughter-bearing minerals,with homogeneous temperatures varying from 100 to 600℃,salinities from 0 to 16 wt%,and gas-liquid ratios from 10 to 60%.[Conclusions]The inclusions in crystals can reflect the physical and chemical conditions of the geological fluids during the formation of crystals,indicate the origin of mineralizing materials and the evolution law of mineral deposits,and provide important information for the genesis mechanism of mineral deposits.
