摘　　要：矿物包裹体(包括温度、压力、盐度及成分)的研究表明南泥湖-三道庄钼(钨)矿床成矿热液的温度、盐度与K^+、Ca^(2+)、SO_4^(2-)等从早阶段到晚阶段均有逐渐降低的趋势。稳定同位素的研究表明成矿溶液的来源,早期以岩浆水为主,晚期以大气水为主。Thoroughgoing studies of the homogenization temperatures, pressures and chemical compositions of fluid inclusions and the stable isotopes of hydrothermal minerals (quartz, calcite, pyrite and molybdenite) have thrown light on the evolution trend of the molybdenum-bearing hydrothermal system which originated from magmatic processes and underwent significant mixing with meteoric waters in the later stages of hydrothermal activities.
