摘要
从铜厂铜矿床矿石的稀土元素，铅同位素特征及示踪结果，结合岩体形成的构造环境与成矿年代资料，指出铜厂铜矿床为岩浆期后热液与动力变质热液叠加复合型矿床。成矿物质既有来自火山岩围岩的，又有源于岩体本身的，是多源复因矿床。
The studies of Pb isotope and tracking,and REE compositions of the ores,combined with the analysis of the rock-forming tectonic setting and dating data of mineralization,have shown that the copper deposit of Tongchang was formed from the post-magmatic hydrothermal process superimposed by the dynamic metamorphic hydrothermal solutions.The ore-forming materials derived both from the volcanic hostrocks and from the rockbodies,indicating that the deposit belongs to the type of multi-souces and compound geneses.
