A pegmatite situated in the Sahasarotra Valley 17 km southwest of the small town Faratsiho in the Vakinankaratra region in the highland of Madagascar. It is located at the northern border of the Vavavato granite massif.
The now-discredited species "ampangabéite" (= altered samarskite-(Y)), was first described from this locality (Lacroix 1912).
