Ilapa, Sahatany Valley, Sahatany Pegmatite Field (Mt Ibity area), Vakinankaratra Region, Antananarivo Province, Madagascar

The locality designed by "Ilapa" consists of several workings around Mt. Ilapa in the NE part of the Sahatany Valley, about 25 km SW of the town Antsirabe. The pegmatites has been worked for gem polychromatic tourmalines and are hosted in a dolomitique marble.
Rakotoarison (1964) describes 3 workings along a 60m long pegmatite at the NNW flanc of Mt. Ilapa, and another one about 350 m further NE.
Minerals, especially pieces of bityite found in the late 1980s originating from Antanetinilapa in the same area are sometimes wrongly labelled as coming from Ilapa.
Rakotoarison(1964) locality nr 14.
