| 摘 要： | 赋矿的峨眉山玄武岩系以爆发相角砾状玄武岩为底,沉积相凝灰岩为顶,可明显划分为三大火山喷发旋回和三岩性段,每一喷发旋回分别对应Ⅰ、Ⅱ、Ⅲ铜矿化层,喷发旋回与铜矿(化)体(层)间存在明显的对应关系,工业矿体由后期含矿构造热液叠加再富集而成。

| Abstract: | The bottom of Emeishan basalt,which is the Cu-bearing bed,is the brecciated basalt of explosive phase,whereas the top of it is the tuff of sedimentary facies.It can be divided into 3 volcanic eruption cycles and 3 members of lithological character.Each eruption cycle is correspondent separately to the Cu metallogenesis bed Ⅰ,Ⅱ,Ⅲ.The commercial ore body is formed by the superimoposed re-concentration of later ore-bearing structural thermal fluid. |
