| Abstract: | As a large gold-bearing province, the Yenisei Ridge does not show elevated background gold concentrations. All types of its sedimentary, metamorphic, and igneous rocks, except only the carbonaceous black shales, contain concentrations of the noble metal at the level of its Clarke values. All local gold deposits are constrained within the regional Central Metallogenic Belt, in which geological–geochemical conditions occurred that were favorable for the deposition of gold and gold–uranium ore mineralization: most of the deposits are constrained within a trough structure, the area was affected by several pulses of plume magmatism, which introduced, redistributed, and concentrated gold and uranium, and the developing ore-concentrating and ore-controlling systems formed economic deposits and associated zones of hydrothermal metamorphism with geochemical aureoles of Pb, Zn, Ag, Au, Bi, and As.
