The Bayanbaolidao gold ore district lies in Sonid Left Banner of Inner Mongolia.The fractured alteration zone and the mylonitized zone are related to gold mineralization of this area.On the basis of geological, geophysical and geochemical achievements,geophysical and geochemical exploration models were constructed.With correlation analysis and "Geshifa" method, the axial zoning sequence of the elements is defined as As-Sb-Hg-Bi-Li-Sr-Ba-Ag-Pb-Au-Cu-Zn-Sn-V-Co-Cr-Ni-Ti-Mo-W.The front halo elements are As,Sb,Hg and Bi.The essential elements that form the mineral deposit are Au, Cu and Zn.The rear halo elements are Ti,Mo and W.According to the axial zoning characteristics,the criterion for the denudation extent of the gold deposit is w(As)×w(Sb)×w(Bi)/w(Ti)×w(Mo)×w(W).The determination of ore-prospecting criteria provides the basis for further geological exploration.
