Abstract: Abstract: [Objective] The Daping gold deposit is an economically significant lode gold deposit in the Ailaoshan orogen of southwest China, with accumulated gold reserves exceeding 55t. Due to years of mining activities, the mine reserves are depleting, making it crucial to conduct deep prospecting prediction research in the mining area and determine the direction for further exploration. [Methods]In order to explore the deep metallogenic potential of the Daping gold deposit, this study focuses on investigating the structural superimposed halo of the main ore body within V8 vein at Baishapo mining area in Daping gold deposit. [Results]The findings reveal a close relationship between Ag, Cu, Pb elements and Au mineralization in Daping gold mine. These elements (Au, Ag, Cu, Pb) serve as indicators for proximal-ore halo characteristics of the Daping deposit. By utilizing an improved Grigoryan zoning index method, we obtained axial zoning sequences for each exploration line. It was observed that each exploration line exhibits "anti-zoning" characteristics indicating multi-stage mineralization events. Combining these results with changes in trace elements and geochemical parameters along with spatial distribution analysis reveals that exploration line 160-200 towards southeast demonstrates head-tail halo superposition suggesting possible extensions of deep ore bodies in that region. A contrast halo zonation map generated through Kriging interpolation method indicates that the ore body lies on the southeastern side at depth levels. [Conclusion]Based on spatial distribution characteristics of ore bodies along with their geochemical properties and element distributions, a ore-finding model for structural superimposed halos has been established for the Daping gold deposit. This model suggests favorable metallogenic space exists within depths corresponding to exploration line 160-200 which has been verified by drilling holes . Thus , the successful practice in this paper shows that the structural superimposed halo method is still one of the effective methods for deep prospecting of vein gold deposits.
