This paper is the result of mineral exploration engineering.[Objective]The Chiwawu copper-molybdenum deposit is located in the northern Taihang Mountains metallogenic belt,which is one of the key exploration zones as part of the'Prospecting Breakthrough Strategy'implementation.However,the mineral exploration in this deposit has entered a bottleneck stage currently.This study aims to provide new target areas for the deposit.[Methods]Identify exploration indicators based on a comprehensive interpretation of the geological,geophysical,geochemical,and remote sensing data of the deposit.[Results]The deposit was formed in the Early Cretaceous and exhibits similar mineralization characteristics to typical porphyry deposits,indicating a close association with deep-seated granite porphyry.Circular structures are widely distributed in the study area,with large circular structures associated with the Chiwawu coplex and other concealed intrusions,while small to macro-sized circular structures are associated with cryptoexplosive breccias or concealed small stocks.There is a strong spatial correlation between the geochemical anomalies and alteration zones discriminated using the remote sensing data,which can serve as an effective indicator for mineralization.Four exploration target areas are delineated.[Conclusions]Within the Chiwawu complex,locating the cryptoexplosive breccias and concealed granite porphyry is crucial for Cu and Mo prospecting,while in the surrounding area prospecting,the focus is recommended to be on Cu,Au,and Ag.
