摘　　要：峨边地区出露的二叠纪峨眉山玄武岩组地层多以溢流相为主,岩石呈深灰色-灰绿色,根据其成因及结构组分特征,可将峨边地区峨眉山玄武岩划分为斑状玄武岩、致密玄武岩、气孔-杏仁玄武岩、凝灰质玄武岩四种岩石类型。并对玄武岩岩石、化学特征开展研究,研究表明区内存在符合拉丝的纤维用玄武岩,具有较好的开发利用前景。The Permian Emeishan basalt formations exposed in the E’bian area are mostly overflow facies,and the rocks are dark gray to gray-green. According to their genesis and structural composition characteristics, the Emeishan basalts in the E’bian area can be divided into porphyry There are four rock types: compactbasalt, porphyriticbasalt, stomata-almond basalt, and tuffaceous basalt. Research on the rock and chemical characteristics of basalt has been carried out, and the research shows that there is fiber-used basalt in the area that is suitable for drawing, which has a good development and utilization prospect.
