Checking geological and geochemical survey was carried out at the Betyugen ore field to outline the gold-antimony mineralization. The study of abnormal structure of the geochemical field was based on lithogeochemical testing results on secondary scattering halos. The geochemical halos controlling the gold-antimony mineralization were found to have a concentrically-zonal structure. Analysis of spatial position of mono-elemental anomalies and multidimensional geochemical indicators revealed zonation of the abnormal geochemical field, which is evident in alternation of the following geochemical associations (with distance from the ore zones): Ni, Со, Pb, Сu → Pb, B, Sn, Ni, Co → Mn, Pb, Sn, Co → Сu, Pb, Ni. The studies allowed outlining of areas promising for gold-antimony mineralization: two areas of the first priority and three areas of the second priority.
Key words: Betyugen ore field, gold-antimony mineralization, abnormal structure of geochemical field, geochemical zonation, secondary scattering halos.
