| 摘 要： | 通过找矿工作的实践，认为锡铁山铅锌矿床是由火山喷流沉积—后期热液叠加改造富集的块状硫化物多金属矿床。区域上NW—SE向早古生代形成的裂谷带，三级盆地内沉积的晚奥陶世滩间山群的大理岩与绿片岩系是表区找矿的最佳区段。而绢云绿泥斜长片岩、含碳质绢云绿泥片岩、白色大理岩、条带状大理岩是铅锌矿的最重要的找矿标志。

| Abstract: | Xitieshan lead-zinc deposit is considered to be a massive sulfide polymetallic 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 NW-SE 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 sericite-chlorite-plagioclase schist, carboniferous sericite-chlorite schist, white marble and band marble are most important indicators for the exploration. |
