摘　　要：通过对镇江金矿床矿石中载金矿物成分、金矿物种类、金成色、金矿物赋存状态和金矿物形态及粒度特征详细研究,认为镇江金矿成矿流体具低温浅成特征,成矿流体经历了硫过饱和、硫饱和及硫不饱和3个阶段,表明成矿复杂性及多世代性,金成矿流体中富硫、铁、硅、氧等元素。金矿物主要以包体金和晶隙金形式赋存在黄铁矿和石英载金矿物之中。This paper discusses characters of mineral components and mineralizing fluid of Zhenjiang gold deposits in Liaoning. It shows character of epithermal gold deposit that concludes features of gold-carrying mineral components, gold mineral species, fineness, occurrences, gold mineral shape and granularity. There ware 3 evolvement stages of ore-forming fluid by sulfur supersaturated, sulfur saturated, and sulfur unsaturated supersaturated periods. In generally, it was rich in sulfur, iron, silicon and oxygen in oreforming fluid. The main gold-carrying mineral is pyrite and quartz. The gold is in the inclusion gold and crystal fissure gold residence in pyrite and quartz.
