中文摘要: 芳村金矿是位于江西景德镇大背坞—瑶里成矿带西段的一个矿床。在野外露头观察的基础上,结合矿相显微镜下鉴定、原矿物化学分析、人工重砂和解离性分析等实验手段对矿区内矿石组分特征以及金矿物赋存状态进行研究。研究结果表明,结晶结构为矿石的主要结构类型,构造包括脉状构造、浸染状构造、条带状构造和斑点状构造。自然金按其嵌存特征分为裂隙金、粒间金和包体金,以包体金为主。自然金粒度大小不一,以细粒金为主,在嵌存类型方面,细粒金在包体金与粒间金中含量以及微粒金在裂隙金与粒间金中的含量符合金在矿化过程中的变化趋向。自然金以毒砂为最主要载体,在石英—硫化物阶段产出。
Abstract:The Fangcun gold deposit is located in the west of Dabeiwu-Yaoli metallogenic belt in Jiangxi. On the basis of field outcrop observation, combined with the experimental means of mineral phase microscopes identification, chemical analysis of the original mineral, artificial heavy concentrate and dissociation to analyze the ore features and gold occurrence in mining. The research result shows that, crystalline structure for the main structure of ore types. Structures consists of vein, disseminated, banded and spotted structure. According to the embedded feature, the gold is divided into interlocking, inter-granular and enclosure, mainly in enclosure. The size is different and commonly fine grain size. The fine grain size in inter-granular and enclosure are accord with the change trend in the process of mineralization. The gold is carried by arsenopyrite and output at the quartz-sulfide stage.
