Relaciones de campo y geoquímica de las carbonatitas de Esquinzo-Agua Salada, NW de Fuerteventura, Islas Canarias

Carbonatites are rather uncommon rocks, the origin of which still stands a subject of debate, especially regarding if they crystallize from primary carbonatitic melts from the mantle, or if they are generated, by some magmatic differentiation process, from an alkaline-silicate parent magma. The Esqu...
