On the basis of conducted field geological, petrographic investigations the magmatic origin of carbonatites of the Sevan ridge is proved, which previously were considered as contact-metasomatic formations – listvenites. These are a new type of carbonatites, which are spatially and in all probability genetically related to ultramaphic complex of Amasia-Sevan-Akera ophiolit zone, without any attributes of connectivity with alkaline rocks formation. It is significant that these carbonatites appear with the presence of accessory minerals of spinell group.
