Rare earth element distribution on the Fuerteventura basal complex (Canary islands, Spain): a geochemical and mineralogical approach

The Fuerteventura Basal Complex comprises Oligocene and Miocene ultra-alkaline-carbonatitic magmatic pulses with outcrops that extend across kilometer-scale areas in some specific sectors of this oceanic island. Additionally, there is evidence of associated weathering materials that affect these mag...
