The Haiyu gold deposit, as a superlarge gold deposit with gold reserves of 470 t and average grade of 4.30×10-6, is a typical Jiaojia-type gold deposit. The authors carried out the rock geochemical survey by the samples from drillholes, and detected the enrichment of Au, Cu, Pb, Zn, Ag, As, Sb, Cd, Bi, S and Fe2O3 and the depletion of Na2O, Ba and Sr in the ore-hosting tectonic alteration zone. The authors systematically summarized the geochemical marks used for exploration. The enrichment of S and Au, or called the positive S and Au anomalies, is the typical geochemical mark of the source rock. The enrichment of S, Au, Ag and Bi and the depletion of Na2O and CaO are typical geochemical marks of the tectonic alteration zone. Based on the above elements and their anomalies, the authors constructed the ore-induced anomaly model of the Haiyu gold deposit, which provides a useful reference for the exploration of the peripheral and deep-seated gold deposits. It is proposed that the main gold orebodies of the ore-forming zone of the sea field may be along ZK2403, ZK3008, and ZK3814 boreholes spread in NEE direction.
