摘要
研究威宁铜厂河铜矿区玄武岩的岩石类型、常量元素、微量元素及稀土元素地球化学特征,探讨玄武岩铜矿的成矿地质背景、控矿因素、产出特征和成矿规律,系统总结了找矿标志。研究认为,本区玄武岩具大陆拉斑玄武岩特征,铜矿属火山同生热液成矿叠加埋藏变质作用改造形成的玄武岩铜矿。
The paper studied rock type, geochemical characteristics of major elements, trace elements and REE of the basalt in Tongchanghe ore field in Weining, discussed the ore forming geological background, ore controlling factors, occurrence and metallurgenic regularities of basalt type copper deposit and summarized the ore prospecting indicators systematically. It is believed that the basalt in the area is characterized by continental tholeiite and the copper deposit belongs to a basalt type copper deposit formed by syn-volcanic hydrothermal mineralization superimposed by buried metamorphic transformation.
