摘要
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.
