Its lower sequence is formed by middle alkaline rocks whilst in the upper one only m ild ly alk ali H y + O I -n o rm a tive rocks are found. The variations in com positio n are largely explained by similar crystal fractionation models for both the lower and the upper sequences. The variation among d iffe re nt basaltic types is due to d iffe re n t extractio n rates o f ab out 10-15%, o liv in e being th e domin ant phase, followed, in a lesser proportion, by dinopyroxene. The difference between the most differentiated basalts and trachybasalts or basaltic trachyandesiles could be explained by extraction of dominant clinopyroxene with plagioclase and Fe-Ti oxide}, publisher = {Sociedad Geológica de España}, keywords = {Canary Island}, keywords = {Fuerteventura}, keywords = {Old Basaltic Serie}, keywords = {Geochemistry}, title = {Características composicionaies y procesos de evolución magmàtica en el complejo volcánico Sur - II de Fuerteventura (Islas Canarias)}, title = {Compositional features and fractionation processes in the Southern Volcanic Complex II Fuerteventura (Canary Islands)}, author = {Cubas, C.
