摘要
在新桥矿田内银金矿体与硫铁矿体的时空关系研究基础上认为,矿田内的银金矿化是早期硫铁矿化基础上的叠加矿化所致,二者受不同的构造控制,矿化特征明显不同。叠加的银金矿化与包村、朝山、狮子山矿田中的金(银)矿化类似,金矿物均与铋矿物具密切的时空及成因联系,矿石中Au、Ag与Bi呈正相关。该认识对区内独立和伴生金银矿成因研究及找矿工作均具有一定的指导意义。
The relationship between Ag-Au ore bodies and pyrite ore bodies in space and time, bismuth minerals and their intimate intergrowth of gold and silver minerals, as well as close correlation between Au and Ag with Bi in ore indicate that the Ag-Au mineralization in the Xinqiao mine is superimposed on the earlier pyrite mineralization instead of associated one. Two types of mineralization are controlled by different structures and different features are shown. The conclusion drawn in the paper is valuable to both prospecting of Ag-Au ore bodies and study of gold and silver recovery.
