The Waqia area is situated within an important metallogenic belt in western China, characterized byabundant mineral resources and favorable geological conditions for mineralization. Based on 1∶50 000 stream sedimentsurvey data, the geochemical prospecting anomaly characteristics of 9 elements, including Cu, Pb, and Zn, were system⁃atically analyzed, leading to the delineation of 115 single⁃element anomalies and 9 comprehensive anomalies. Integratedevaluation of these geochemical prospecting anomalies within the geological context was conducted, and the QianzilafuPb-Zn-Cu Deposit was discovered through anomaly verification. By systematically evaluating geochemical prospectinganomalies and analyzing the prospecting effect, an applicable metallogenic model was established. Results indicate thatthe discovery of the Qianzilafu Deposit validates the effectiveness of the 1∶50 000 geochemical prospecting anomalyevaluation method and provides new insights and methodologies for evaluating geochemical prospecting anomalies insimilar geological environments. By studying ore⁃controlling geological factors and metallogenic characteristics, a strat⁃abound and hydrothermal superimposed Pb-Zn-Cu metallogenic model for the Waqia island arc was successfully estab⁃lished, offering significant guidance for subsequent regional mineral exploration.
