Аннотация:Based on a factor analysis of the geochemical and mineralogical data on drill holes, the geochemical associations that allow the localization of the areas of mineralization at different stages of the formation of the Nakhodka porphyry-epithermal system were determined. The lateral and vertical geochemical zoning of mineralization was described. Geochemical indicators of vertical zoning (AgPbZn/CuBiMo and AgAsSb/CuBiMo) that provide estimates of the erosion level of porphyry-epithermal systems and porphyry copper stockorks were suggested.
