Geological Characteristics and Genesis of Lead Deposit in Shawo Town,Henan Province
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.
