Abstract

In the article genetical problems of carbonatites of the Sevan ophiolite zone are discussed. According to the authors, carbonatites are genetically related to hyperbasites and are a new formation type of mantle rocks, which absolutely differ from classic carbonatites of alkaline ultrabasite complexes. The issue of impossibility of the occurrence of alkali-ultramafites and alkali-carbonatites from depleted of alkali elements magma of the upper mantle has been discussed.
