The Quaternary Vakinankaratra volcanic field is at the SW end of the larger Neogene Ankaratra volcanic field. Melluso et al. (2016) noted that there were extensive lava flow fields, domes, Strombolian scoria cones, tuff rings and maars. Rufer et al. (2014) used K-feldspar infrared-stimulated luminescence (IRSL) dating, finding ages of 32 ± 3 and 19 ± 2 from phreatomagmatic deposits near Lake Tritrivakely; they reported other dates in the 40-126 ka range.
