| 摘 要： | 通过工作实践认为，大坪银-铅-锌多金属矿床是火山喷流沉积一后期热液叠加改造富集的块状硫化物多金属矿床。区域上NWW-SEE向晚元古-早古生代形成的裂谷型二郎坪蛇绿岩套是本区找矿的最佳区段，具四个含矿层位。矿化、矿石、矿物、元素等成矿作用要素具明显分带特征，并与火山作用及喷流作用有关。区域构造、同生断裂及岩浆作用为重要控矿条件，而硫化物层、重晶石层、硅质岩是银-铅-锌矿床的重要找矿标志。

| Abstract: | Daping silver-lead-zinc-polymetallic deposit is considered to be a massive sulfide polymeta deposit formed by hydrothermal liquid superimposed transformation and enrichment of late stage volcanic effusion and deposition according to the field evidences. The regional early Paleozoic NWW-SEE strike rift zone and late Ordovician Tanjianshan Group marble and greenschist strata deposited in the third order basin are the favourable area for prospecting in the region. And sulphide bedding,barite bedding are most important indicators for the exploration. |
