Abstract
The particularity of the formation of the skarn lodes of the Cretaceous-Paleogene Belogorsk deposit is the intense replacement of the early mineral assemblages (the decomposition of garnet, pyroxene, and pyroxenoids) with decreasing temperature, the increase in the amount of magnetite at the expense of Fe released from the decomposed minerals, and the formation of quartz and volatile-rich compounds (calcite, fluorite, amphibole, and sulfides). The geochemical and mineralogical similarity suggests a genetic relation between the manganese skarn lodes of the Belogorsk deposit (the Ol’ginsk ore district) and the stratabound bodies of the manganese silicate rocks (the Triassic contact metamorphosed metalliferous sediments) of the adjacent Shirokaya Pad area (as a source of matter).
