They named the element gadolinium after Johan Gadolinand its oxide was named “gadolinia”. European Commission for the ‘Development of a sustainable exploitation scheme for Europe’s Rare Earth ore deposits’. The classification of rare-earth elements is inconsistent between authors.

Carbonatites crystallize from CO 2 -rich fluids, which can be produced by partial melting of hydrous-carbonated lherzolite to produce a CO 2 -rich primary magma, by fractional crystallization of an alkaline primary magma, or by separation of a CO 2 -rich immiscible liquid from.
