An uranothorianite deposit situated near Andranokaolo and close to Morafeno. Located 12 km SSW of Tranomaro in the southeastern part of Madagascar. The deposit is located at the SE foot ot the Antaritarika hills. A 12 wide and 300 m long band in a diopsidite (pyroxenite) has been worked for uranothorianite.
Coordinates are not confirmed, based on map of Brenon (1957).
