摘　　要：概述了峨眉山玄武岩的成因及火成岩类的三种成因模式,对峨眉山玄武岩与地幔热柱的密切关系进行了探讨;介绍了玄武岩型铜矿的命名、矿化类型及其在川滇黔地区的分布特征;通过与国外基伟诺玄武岩铜矿床的成矿地质特征进行对比,分析了两者的不同之处;对其成矿物质来源、水循环系统、构造、地层及容矿岩石和古油气藏等成控矿条件进行了进一步的分析和总结,指出了川滇黔玄武岩铜矿的找矿远景区和找矿方向。The present paper deals with mineralization type, distribution in the Sichuan- Yunnan-Guizhou border region and genesis of the Emeishan basalt-hosted copper deposits and 3 genetic models for the host rock and makes an approach to the close relationship of the Emeishan basalt with mantle plume and compares the Emeishan basalt-hosted copper deposit with Keweenaw basalt-hosted copper deposit. Ore material source, water circulation system, structure, stratigraphy, host rock and old oil and gas accumulation are discussed and prospecting potential and range of reconnaissance for the copper deposits.
