Minerals of kyanite group are used in high-fireproof materials’ industry Two groups of productive mctamorphic-metasomatiс rocks enriched by high-aluminiferous minerals are distinguished: 1) stratificated horizons in a rock mass of the Archean and Proterozoic plagiogneisses - aluminiferous formation of continental shields and ancient platforms (metamorphogenic Keiv type); 2) non- stratificated metasomatic rocks of inward and outward suture zones of polyfacies metamorphic complexes of andalusite-sillimanite thermodynamic types formed in different ages pelitic rocks aluminiferous formation of folded belts (hydrothermal metasomatic Uralian type).
