The mafic alkaline volcanism of SW Madagascar (Ankililoaka, Tulear region): 40Ar/39Ar ages, geochemistry and tectonic setting

High-precision40Ar/39Ar ages, major and trace element, and radiogenic isotope data are presented for the basanites and alkali basalts forming the southwesternmost monogenetic volcanic field in Madagascar. The volcanic rocks were erupted along fissure zones and aligned cones in a nearly flat area cov...
