| 摘 要： | 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。

| Abstract: | The deep exploration to Xitieshan Pb-Zn deposit found that the orebodies be-low 3062 level with more complex shape and a displacement toward northeast. Because of thediscovery of blind orebodies in deep,the reserve increases 73. 73 percent,the grade of Pb andZn increase 60. 9 percent and 7. 49 percent separately. The orebodies were divided into fourtypes according to the relationship between orebody and marble, the orebodies occured in themarble is main one. The deposit is a kind of massive sulfide deposit formed by marine vol-canic emanation-sedimentation and superimposed by metamorphsim and faulting. |
