dc.description.abstract	Greenschists and alternating, smaller beds of graphite schists, felsites, together with intrusive rokcs of diabase and granitoid character, all belonging to the Karelidic orogeny, show strong enrichment of albite. Chemical analyses demonstrate the Na2O content amounting for 10 per cent. Details of the most albite rich rocks are given. It is suggested that the intrusive rocks are derived from palingenic magmas, inheriting the Na2O richness from geosynclinale or early orogenic spilitization processes.
