Abstract

The banded-disseminated ores are characterized, for which the manifestation of silicate-oxide (olivine, spinel, plagioclase) fractionation, silicate-sulfide and chalcopyrite- pyrrhotite immiscibility is shown. It has been established that the sulfide melt accumulates not only fluids (Cl, P, H2O), but also petrogenic components (SiO2, Al2O3, TiO2, FeO, MgO, CaO, K2O), which cause iron oxidation, the appearance of hydroxyl-containing minerals and various types of metasomatic reactions, mobilization and spatial redistribution of noble metals and chalcophile elements.
