Resumo

Results of ontogenetic studies of the early paragenesis of ore minerals in zonal clinopyroxenite-dunite massifes of the Middle Urals are discussed. It is shown that the formation of these minerals occurs in the following order: iridosmium → chrome-spinel → laurite-erlichmanite → оsmiridium → isoferroplatinum. Revealed ontogenic features of ore phases are in good agreement with models suggesting the concentration of platinum group metals at the magmatic stage of evolution of the clinopyroxenite-dunite massif before display of the superimposed high-temperature plastic deformation.
