Geological Characteristics and Prospecting Prediction of Ligou Lead-zinc Deposit in Ruyang County,Henan Province
The Ligou lead-zinc deposit in Henan is situated on the southern edge of the North China landmass,within the Lushi-Luanchuan-Nanzhao-Fangcheng polymetallic mineralization belt,characterized by favorable geological conditions for mineralization.A thorough analysis of the regional geological background,the geological characteristics of the mining area,and the deposit itself was performed,summarizing ore exploration indicators such as structural features,alteration,and geophysical anomalies,and making predictions for ore exploration.The study reveals that the ore bodies are predominantly hosted in early structural fracture zones trending east-west and northeast,exhibiting a vein-like or lens-like distribution along these zones.The morphology and orientation of the ore bodies are strictly governed by the fracture zones.The associated rock alteration is predominantly sericitization,silicification,and chloritization,with carbonation occurring less frequently,and these alterations are closely associated with lead mineralization.The EH4 magnetotelluric(MT)sounding effectively delineates mineral-induced anomalies.The findings suggest that the EH4 MT sounding method can swiftly identify anomalous bodies of lead-zinc mineralization,offering valuable insights for the exploration of similar deposits in the region.
