| 摘 要： | 铜山铜矿床是长江中下游铜铁成矿带的重要矿床之一，对其成矿物质以前多认为来自单一的岩浆期后热液。通过综合分析成矿元素在各地质体中的分布及矿床同位素地球化学特征，认为：其成矿物质来源复杂，具多源性；不同类型矿石其成矿环境不同；围岩在成矿作用过程中提供了部分物质来源；花岗斑岩岩体、层间滑脱构造及有利围岩组合是矿床成矿的主要因素。

| Abstract: | tongshan copper deposit is one of the important deposits in Yangtse River Mid-downstream copper-iron ore belt. It was believed that the ore matter was origin in post magmatic thermal fluid exclusively. The comprehensive analysis of the distribution of ore elements in various geological bodies and the isotope geochemistry of the deposit shows that the source of the ore matter is rather complicated, which origin in multiple sources and different type of ore occur in different ore-forming environment. The country rocks supplied part of the ore matter and the combination of granite porphyry, inter-layer detachment structure and favourable country rocks is the main factor for the mineralization of the deposit. |
