Abstract: After a long period of exploration and prospecting work, Linglong gold deposit in Jiaodong has formed a three-in-one Linglong type gold deposit prospecting model, consisting of quartz vein type gold deposits in secondary faults exposed on the surface, altered rock type gold deposits hidden in main faults, and deep ore bearing ore bodies. Studying the characteristics of gold deposit of this type and determining simple and efficient geochemical prospecting indicators for rock and ore bodies are of great significance for predicting and identifying the existence and hidden positions of deep mineralization-related ore-forming rock mass. By analyzing the geochemical characteristics of shallow gold deposits, deep ore bearing rock bodies, and intermediate acidic rock bodies located close to and far from the mining area in Linglong region, the authors found that Linglong type gold deposit is related to crustal mantle magmatic activity mixed with subducting oceanic crust materials. The geochemical characteristics, which can reflect the genesis of the rock body and ore, including loss on ignition, rare earth element distribution patterns, δEu values, Nb/Ta values, Ti/V values, Te Au relationships, and SiO₂-P₂O₅ relationships, can be used as indicators for the geochemical exploration of Linglong type gold deposit. Based on this method, preliminary prospecting directions were predicted for similar mineralization areas such as Jiaojia gold mine, Sanshan Island gold mine, and Liaodong Wulong gold mine, providing basis for subsequent exploration work. This study could provide references for research on Linglong type gold deposits and the exploration and prediction in deep-seated hidden areas.
