N2 - A limited occurence of metacrystals and pseudomorphs of secondary minerals, including tulameenite, tetraferroplatinum, ferronickelplatinum, makes a difference between Kondyor massif and Ural or Koryak zoned clinopyroxenite-dunite massifs of folding regions. A prevalence of tetraferroplatinum-group minerals among total amount of PGM from chromitites of Ural or Koryak zoned massifs is a result of their island arc origin, where the basic magmatism is accompanied by large amount of water fluids (Ivanov, 2011). Limited presence of secondary minerals can appear to be typomorphic sign of PGM association in chromitites from clinopyroxenite-dunite massifs formed in inner parts of platform.
