Based on systematic collection of rock and ore samples from 41 drill holes along No. 4 and No.11 exploration lines in the Zijinshan copper-gold deposit of Fujian Province,the authors drew a contour map of primary halos,established vertical element zoning sequence and orebody denudation guidelines and, in combination with characteristics of the indicator elements in the depth,made a prediction of concealed orebodies.For gold orebody, the near-halo is Au-Ag-Zn¹, and the rear halo is Bi-Ga-Mo-Sn-Ti-Co-Ni-W¹-V, whereas for copper orebody, the front halo is Hg-Sb-As, the near halo is Cu-Pb¹-Zn², and the rear halo is Be-W2. The evaluation of the denudation of the orebody shows that the high-sulfur copper orebody pinches out to the depth. The abnormal morphology and elemental composition of F-Mn-Pb²-Zn³ in the depth is consistent with the characteristics of a typical porphyry deposit, the porphyry body extends to the periphery of the deposit, and the deep alteration mineral assemblages, metal mineral assemblages, fluid inclusion characteristics show that there may exist a porphyry Cu (Mo) deposit in the depth of the southwest part.
