The locality-name Ambatonapetraka refers in the literature to a small numbers of pegmatite dikes of complex type (LCT) that has been worked for gem tourmaline situated N of the village Ambatonapetraka. These dikes are located in the northern part of the Sahatany Pegmatite Field.
This is the same locality that Lacroix (1922) refers to as the Miandrarivo pegmatites (and also as Antsofimbato), and by Guigues (1954) as Antsofimbato IV. It is located about 500 NV of the Antsofimbato pegmatites.
The pegmatite dikes is hosted in an altered sillimanite-garnet-mica schist (Rakotoarison 1964). The pegmatite is strongly kaolinitized.

Rakotoarison (1964) locality nr 1.
Ranorosoa (1986): P28 and P29.
