Technique and results of the depth determination of mantle differentiation of magmatic rocks from greenstone structures (GSS) of Pridnieprovian block of the Ukrainian Shield according to mineral and chemical composition of volcanogenic and ferruginous layers have been presented. The unity of deep development in the Archean has been found. Changes of concentrations of active components and chemical reactions in asthenospheric layer have been considered, which determine s ingularity of GSS rocks, composition of attendant mineral deposits.
