2 large granite pegmatites situated ca 25km W of the town of Ikalamavony, W of the city of Fianarantsoa in the main Highland of Madagascar. They were mined for beryl. The largest of the pegmatites is embedded in a pyroxene-gneiss and measures 200 m long and 15 m wide, and it is one of the few amblygonite-bearing pegmatites that are found in Madagascar.
