This locality consists of three pegmatites of complex type LCT that has been worked for gem tourmalines and spodumene. It is situated NE of the village Samizaza and SW of Maharitra in the western part of the Sahatany Pegmatite Field, S of the town Antsirabe in the main highland of Madagascar.

The names "Ampasihiatra" and "Ampazikahitra" that the locality sometimes has referred to in literature, are misnomers (spelling mistakes).
