Abstract To know about the distribution rule of primary halo in Huachanggou gold deposit and improve the efficiency of prospecting and exploration, the paper makes the element correlation analysis, R-mode cluster analysis and factor analysis of the primary halo, combined with the field survey and previous research results, and obtains the ideal zoning combination of Huachanggou gold deposit as follows:As-Te-Sb-Hg for the front halo, Ag-Au-Bi-Pb-Zn-Se for the near-ore halo and Sc-Co-Ni-Mo-Cu-Cd-Mn for the rear halo, with Sc-Se-Mn-Cu-Cd-Ni-Zn-Ag-Au-Pb-Sb-Mo-Te-Co-Bi-Hg as the zoning sequence of main ore belt. Combined with the ideal model of primary superimposed halo, it is concluded that the orebody is discontinuous from Level 1150 m to Level 990 m, that is, the orebody extending from Level 1070 m downward and pinching out near Level 1030 m, then appearing again from Level 1030 m to Level 990 m, showing a tendency of deep extension.
