摘　　要：滇东北与玄武岩有关的铜矿床是我国近年来矿床学研究和资源勘查的热点之一。通过对该地区进行的资源勘查和科学专项研究,发现含矿岩系主要由上二叠统峨眉山玄武岩组(P3e)上部(第三岩性段顶部和第四岩性段)和宣威组(P3x)底部地层组成,在这套地层中识别出5个矿化层,对5个矿化层的岩性组成、矿化特征和成矿前景进行全面总结,为该区域进一步开展找矿勘查和评价提供了方向和依据。In the past years, the study on copper deposit in the Emeishan Basalt Formation is one of interesting topics in the exploration of mineral deposit. According to our survey, the ore-bearing rock series in this area include the upper part of the Emeishan Basalt Formation （the third and fourth lithologic members） and the base of the Xuanwei Formation. The ore-bearing rock series can be divided into five mineralized beds. The petrology, mineral assemblages, and ore potential of these five beds are characterized. The results form a basis for the exploration and evaluation of copper deposits in this area.
