摘　　要：流体包裹体分析是现代矿床学研究的一个重要手段,对矿床类型的划分及成矿流体成分、温度、压力的研究有着重要的作用。在矿质沉淀的主要机制中,流体相分离及流体混合的主要证据来自流体包裹体;对金属在气相中的搬运的认识,也主要来自包裹体研究。成矿流体成分对认识金属在热液中的搬运方式起着重要作用,流体温度和压力数据是成矿流体动力学模式的重要制约。Fluid inclusion analysis is an important tool in modern studies of mineral deposits, as reflected by the statistics indicating that about a quarter of the papers published in Economic Geology contain fluid inclusion studies. Fluid inclusions play an important role in the classification of mineral deposits and in the study of the composition, temperature and pressure of mineralizing fluids. Among the principal mechanisms of ore precipitation, flu- id phase separation and fluid mixing derive their key evidence mainly from studies of fluid inclusions. Data on mineralizing fluid composition obtained from fluid inclusion analysis are key to understanding how metals were transported in hydrothermal fluids. Recent progresses in metal transport in vapor have been mainly contributed by fluid inclusion studies. Data on fluid temperature and pressure from fluid inclusion studies provide important constraints on hydrodynamic models of mineralization.
