Owing to mining in the past successive years,the reserves have become less and less in Yichuan area.In order to speed up exploration of lead-zinc polymetallic deposits,the authors systematically analyzed metallogenic geological background and ore-controlling conditions of known deposits in Yichuan area,conducted proper conversion processing and analysis of the aeromagnetic data of the related deposits,and inferred and extracted aeromagnetic indicators of the deposits.Combined with the analysis of metallogenic geological conditions,the aeromagnetic anomalies with prospecting potential could be quickly identified.With two examples of aeromagnetic anomaly inspection,the better geophysical and geochemical anomaly features were found.The mineralization belt (body) exposed by trenching shows that the aeromagnetic indicators have high practicality and can be adopted as clues in search for the same type of lead-zinc polymetallic deposits in Yichuan area.
