Abstract

The main task of constructing geochemical models of ore deposits are justification the mineralization forecast
depth, determination the denudation level of ore occurrences detected by lithochemical survey for secondary scattering
halos, and taxing ore intersections in accordance of a genetically similar well-studied (reference) field. The principle of
geometric and geochemical similarity of genetically similar objects is used for predictive evaluation of the studied objects
at the early stage of exploitation. Based on the construction of generalized models of sections of polymetallic deposits in
combination with geochemical features, a forecast estimation of mineralization is given.
