Iron-ore formations of Volchansk thickness are correlate with the same of bryansk thickness of oboyan series of Voronezh crystalline massive, not with iron-ore formations of kursk series. Age limits of formation of krivorozhskaya and kurskaya series of Voronezh kristaline massives and Ukrainian Shield with connected huge supplies of iron ores are pr?cised significantly - 2690-2150 million years. Evidental juxtaposition of regovskaya suite oskolskaya series with gdantsevsk suite of krivorozhskaya series is determined, therefore necessity of changes in stratigraphy scheme is obvious.
