摘　　要：对金顶铅锌矿床各成矿阶段流体包裹体进行了均一温度和盐度测试、计算了其形成压力。包裹体在矿床成矿热液期广泛发育,根据包裹体室温下的成分-相态,将其分成富有机质包裹体、气液固三相包裹体、纯液相包裹体等类型。根据流体包裹体测温结果和流体化学成分初步认为该矿床成矿流体主要来源于盆地热卤水。根据流体包裹体的研究反映了有机质或富有机质的还原性流体与盆地卤水参与了铅锌矿成矿过程。The uniform temperature and salinity test was carried out for fluid inclusion at each metallogenic stage of Jinding lead-zinc deposit,and the compacting pressure was calculated.Inclusions are widely developed during the metallogenic hydrothermal period of the deposit,according to the composition-phase state of the inclusions at room temperature,they are divided into organic-rich inclusions,gas-liquid-solid three-phase inclusions,and pure liquid-phase inclusions.According to the temperature measurement results of fluid inclusions and the chemical composition of the fluid,it is preliminarily believed that the ore-forming fluid of the deposit mainly comes from the basin thermal brine.According to the study of fluid inclusions,it is reflected that organic matter or organic-rich reducing fluids and basin brine are involved in the mineralization process of lead-zinc ore.
