摘　　要：锡铁山铅锌矿床的形成受原始沉积盆地及古地理环境、同生断裂的影响较大。从矿区范围看,热水喷流的矿化结构典型,元素分带趋势较明显,具喷流沉积矿床分带的基本特征。鉴于目前仅揭露层状铅锌矿带,层状硫化物之上或其侧向的层状重晶石相和铁氧化物相未出现,沿矿体倾斜方向的铅锌硫化物带尚有很大空间,深部找矿潜力巨大。The formation of Xitieshan Pb-Zn deposit is greatly influenced by the original sedimentary basin, palaeogeographic environment and syngenetic faults. The mineralization structure of hot water jet is typical and the trend of element zoning is obvious. It has the basic characteristics of the zoning of exhalative sedimentary deposits. In view of the fact that only layered Pb-Zn ore belts have been exposed at present, the layered barite and iron oxide facies above or laterally to the layered sulfides have not appeared, and the Pb-Zn sulfide belts along the inclined direction of the ore bodies still have great space and great potential for deep prospecting.
