THE PROBLEM OF CARBONATITES AND CARBONATITE COMPLEXES
На підставі аналізів авторських та літературних даних зроблено висновок про те, що первинний склад більшості карбонатитів був лужнокарбонатний типу карбонатитів і туфів вулкану Олдоіньо-Лентаї (з високим вмістом Na2CO3, K2CO3, CaCO3 і підпорядкованим – MgCO3, FeCO3).
