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。 Based on the characteristics of rare earth elements and lead isotopes and the trace results of the lead isotopes in the copper deposit of Tongchang Copper Mine and the tectonic environment and metallogenic age data of the rock mass, it is pointed out that the Tongchang copper deposit is superimposed with hydrothermal metamorphic hydrothermal fluids after the magmatic period Complex deposit. Mineralization material from both volcanic rock, but also from the rock itself, is a multi-source complex deposit.
