Mineralogical and geochemical characteristics of gabbros in the Los Molinos area, Fuerteventura (Canary Islands)

Gabbros of Los Molinos area crop out in the northwest part of Fuerteventura (Canary Islands).They are formed by different types of gabbros, and their mineralogy and geochemistry are presented in this work.The results indicate that the most fractionated gabbros are leucogabbros situated in the upper...
