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.
Abstract
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.
