锡铁山铅锌矿床深部生产勘探发现,3062米中段以下矿体比地质勘探时控制的形态复杂,普遍向北东位移。在无矿段和深部发现品位较富的盲矿体,使矿石储量增加73.73％,铅锌品位分别提高60.9％和7.49％。依矿体与大理岩之关系,矿体分为四种类型,赋存于大理岩中的矿体为主矿体。矿床具分带性,为海相火山喷流沉积——变质改造叠加型的块状硫化物矿床。
The deep production exploration of the Xieshan lead-zinc deposit shows that the ore body below the mid-3062 meters is more complicated than the geological exploration and generally moves to the northeast. In the non-ore-bearing section and deep discovery of relatively rich blind ore bodies, the ore reserves increased by 73.73% and the lead and zinc grades increased by 60.9% and 7.49% respectively. According to the relationship between ore body and marble, the ore body is divided into four types, and the ore body hosted in marble is the main ore body. The orebodies are zonogenic and sedimentary-metamorphic remodeling superimposed massive sulphide deposits for the marine volcanic jet.
