摘　　要：礼岷前陆盆地经历了早期深海—半深海的复理石沉积阶段和晚期陆相磨拉石沉积阶段。该盆地在成盆及盆山转换过程中在其前渊、隆后盆地以及褶皱冲断带内形成了Au、Ag、Pb、Zn、Cu、Mo等多金属矿床。The Lixian-Minxian foreland basin undertook abyssal-bathyal flysch deposition at its earlier evolution stage and continental molasse stage at its later evolution stage.Au,Ag,Pb,Zn,Cu and Mo polymetallic deposits were formed at its foredeep, back-uplift basin and fold-thrust belts during its forming and the basin-range transformation.
