ISOTOPE COMPOSITION OF CARBON AND OXYGEN IN CALCITES OF ALKALINE ULTRAMAPHIC DYKES WITHIN THE URIK-IYA GRABEN

The isotope composition of carbon and oxygen was studied in calcite of dykes and veins of ultramafic lamprophyres, kimberlite, alkaline mica picrites from the Yarma above-intrusion zone, and pyroxene-free picrites intruding the rocks of the Bolshetagninsky carbonatite massif within the Urik-Iya grab...
