| Abstract: |
| Major breakthroughs have been made in the national "358" ore prospecting breakthrough strategic action in Shanggong gold ore field, and the F60 vein is one of the more special veins. The geological characteristics of F60 vein, the zoning characteristics of primary halo in boreholes and the affinity of elements were analyzed. It was shown that the near halo elements of the deposit are Ag, Au, Pb, and Zn, the front halo elements were As, Hg, and Cu, and the tail halo elements were W, Mo, Mn, and V. The deposit did not have the characteristics of superimposed halo formed by multi-stage superimposed mineralization, hence, there was little possibility of blind orebodies in the deep. The prospecting direction of the deposit was in the shallow area without engineering control. Element affinity analysis indicated that the near-halo elements including Ag, Au, Pb and Zn had a strong correlation with each other, and W, Mn and Hg can be used as indicative elements for geochemical prospecting. The research results can be used as a reference for the study of primary halo geochemistry of similar interlayer structure-controlled gold deposits in the region. |
