摘　　要：万载高城金矿为萍乡-高安凹陷带重要的金矿资源,其类型为石英脉型金矿。本文通过对该金矿区的矿物组合特征、结构构造特征的研究,将成化阶段划分为热液期和表生成矿期。其中热液期分为石英-黄铁矿阶段、石英-多金属硫化物阶段、石英-闪锌矿-黄铁矿阶段、石英-碳酸盐阶段。石英-黄铁矿阶段和石英-多金属硫化物阶段的矿物组合特征可作为该地区找矿标志,对该地区的金矿找矿研究有积极意义。Gaocheng gold deposits located in the west of Pingxiang-Gaoan Depression.At present,few studies have been carried on quartz vein-hosted gold deposit,the most important type of gold deposit in this area.Based on the ore textures,the structure and the mineral assemblages,the ore-forming processes are divided into four stages:quartz-pyrite stage(stage玉),quartz-polymetallic sulfide stage(stage域),quartz-sphalerite-pyrite stage(stage芋)and quartz-carbonate stag(stage郁).The primary ores were formed at stage玉and域,which could be the important prospecting indications in this area.
