A complex type LCT pegmatite, tending to elbaite subtype, that has produced many good polychromatic tourmalines. It is situated just SW of the confluence of the Ampahitra with the river Sahatany in the Sahatany Pegmatite Field, SW of the town Antsirabe in the main highland of Madagascar. It was described by A. Lacroix (1922) by the name Ambalaroy, a name that is not in use today. This locality should be distinguished from Tsarafara Sud (=Ankadilava) that is situated some hundred meters from here.
A flood washed through the locality in the 1980s and swept away all the debris.
