Study on comprehensive geophysical and geochemical prospecting methodology for lead-zinc polymetallic deposits in Hutouya,Qinghai Province
The Hutouya deposit is located in the eastern part of the Qimantage region,Qinghai Province,which is rich in diverse mineral resources with complex combinations,harboring tremendous potential for prospect-ing.This study,tailored to the unique geological conditions of alpine regions in this area,focuses on resolving the challenges associated with the exploration of concealed non-ferrous metal deposits,aiming to efficiently and accurately identify and locate the spatial distribution of concealed ore bodies in alpine environments.A pilot study based on a comprehensive geophysical and geochemical prospecting methodology was designed and implemented.The study utilized dual-frequency induced polarization(IP)scanning technology,coupled with high-frequency magnetotelluric sounding methods,to acquire the electrical characteristics of deep geological structures,effectively distinguishing mineralization anomalies from non-mineralization anomalies.Additionally,geochemical prospecting techniques involving primary and secondary halos were incorporated,with multi-element geochemical anomaly analysis further predicting the spatial distribution of mineralization.The application of these comprehensive exploration techniques achieved promising results in the Hutouya area of Qinghai,delineating potential mineraliza-tion zones and exploring effective prospecting techniques tailored for concealed non-ferrous metal deposits in alpine regions.The methodologies employed in this study can serve as a valuable reference for prospecting in surrounding exploration areas and concealed strata in alpine regions.
