Abstract <p>Natural transport of gold is a stable and permanent process in the zones of hypergenesis in gold-bearing rock masses. Dissipation and concentration of gold depend on the geochemical barrier conditions of mass transport. One of the main agents in hypergenic transformation of a substance are natural humic compounds—steadfast participants in hypergenesis. The experimental selection of a geological prototype for the hydrochemical mass transport and concentration of gold is carried out for the conditions of the mantle. The pacing factors and probable mechanism of hypergenic concentration zone formation are presented with regard to the properties of fractions of humic substances.</p>
