摘要
紫金山矿床是２０世纪８０年代后期在我国发现的大型金铜矿床。该矿床成矿与地层关系不大，主要受多期次复合岩体、火山－次火山岩体和隐爆角砾岩控制，围岩蚀变和矿化具多期次的叠加特点。矿床就位于统一的构造空间内，属岩浆期后热液成因（为主）矿床。
Zijinshan goldcopper deposit is a largesized one found in late 1980s in China.The mineralization of the deposit has not much relation with stratum.It is controlled mainly by multiphasic and repeated composite rock mass,volcanicsecondary volcanic rock and concealed explosive breccia.The alteration of country rock and mineralization have the characteristics of multiphasic and repeated superimposition.The deposit takes its place in unified tectonic space,so it belongs to postmagmatic deposit of hydrothermal genesis.
