Minerales de tierras raras en las carbonatitas del Complejo Basal de Fuerteventura (Islas Canarias)

The Fuerteventura carbonatites appear in the Complejo Basal as veins, breccias and shear bands in the coastline between Puerto de la Pena and Cueva de Lobos, and in the Esquinzo ravine zone. These carbonatites are formed by calcite mainly and apatite, aegirine-augite, albite, orthoclase-sanidine, bi...
