| 摘 要： | 从江翁浪金矿受构造蚀变带控制。通过对蚀变岩石及其中黄铁矿单矿物进行含金性测试发现金矿化与黄铁矿关系密切。本文利用矿相学、化学分析和电子探针技术等地质地球化学手段对该矿床黄铁矿特征进行了研究。结果表明矿床中含金性较好的黄铁矿一般颗粒细小;早世代黄铁矿的含金性比晚世代好;金形成于贫S、低S逸度介质环境;晶胞中S过剩的黄铁矿含金量相对较高。

| Abstract: | Wenglang gold deposit in Congjiang is controlled by structural alteration zone.By gold potentiality test to the alteration rock and its pyrite ore,it＇s found that the relationship between pyrite and gold mineralization.In this paper,it studies the pyrite character of this deposit by use mineralography,chemical analyses,electro probe and other geochemical measures.The result shows that the pyrite which the gold potentiality is good,its grain usually is small,the gold potentiality of pyrite in early generation is better than in the late generation.The gold is formed in the media environment of poor and low S fugacity.The gold content of pyrite which the S is surplus in the unit cell is higher. |
