摘　　要：分布于盐源桃子乡一带的峨眉山玄武岩具有厚度大、构造应力集中和深部有基性、中酸性、酸性系列岩浆侵入活动等特征,具备形成规模以上矿床的潜力。近年来,随着全国矿产资源潜力评价工作的有力推进,有关峨眉山玄武岩型铜矿床成矿理论研究已取得了一些重要成果,但勘查效果不佳。文章综合利用研究区内最新的地质勘查、地球物理勘测成果,重点讨论了区内玄武岩型铜矿床的成矿规律和找矿前景,认为矿化受层位和构造热液控制,并进一步明确了矿体与地层、岩性及构造之间的成因联系。The Emeishan basalt in Taozi Township, Yanyuan is characterized by large thickness, concentrated tectonic stress and basic, intermediate-acidic and acid magmatic intrusive intercalations in the depth which makes a Cu deposit possibly formed. In recent years, with the vigorous advancement of the national mineral resources potential evaluation work, the research on metallogenic theory of the Emeishan basalt type Cu deposit has made some important achievements, but the exploration effect is not good. This paper focuses on the metallogeny and prospecting potential of the basalt type Cu deposits based on the last geological exploration and geophysical survey results in this area. It is believed that the mineralization is controlled by the stratigraphic horizon and tectonic hydrothermal solution.
