摘　　要：沙窝镇铅矿区是华北地台南缘东西向铅、锌、钼、金等多金属成矿带的有利地区。对矿区区域地质和矿体地质特征进行总结,分析矿石特征,划分矿石类型,最后对矿床成因进行了探究。研究结果认为,矿区铅锌成矿具有热液活动多期性和多阶段性,成因类型为中—低温热液矿床;矿体赋存浒湾岩组黑云斜长片岩、二云斜长片麻岩中,受构造破碎带控制;圈出4个工业铅锌矿体,矿石类型为石英-方铅矿型铅锌矿石和大理岩-方铅矿-多硫化物型铅锌矿石2种类型,为铅资源的进一步勘查提供了依据。Shawo Town lead mining area is a favorable area of lead,zinc,molybdenum,gold and oth⁃er polymetallic metallogenic belt in the south margin of North China platform.This paper summarizes the re⁃gional geology of the mining area and the geological characteristics of the ore body,analyzes the ore charac⁃teristics,divides the ore types,and finally discusses the genesis of the deposit.The results show that the mineralization of lead-zinc ore in the mining area has multi-stage and multi-stage hydrothermal activity,and the genetic type is medium-low temperature hydrothermal deposit.The orebodies occur in the biotite plagioclase schist and Eryun plagioclase gneiss of the Huwanyan Formation,which are controlled by the tec⁃tonic fracture zone.Four industrial lead-zinc ore bodies are identified,and the ore types are quartz-galena type lead-zinc ore and marble-galena-polysulfide type lead-zinc ore,which provides a basis for further ex⁃ploration of lead resources.
