Características composicionaies y procesos de evolución magmàtica en el complejo volcánico Sur - II de Fuerteventura (Islas Canarias)
The Southern Volcanic Complex II consists mainly of basalts with some trachybasalls and basaltic trachyandesltes. 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...
