A complex type LCT pegmatite worked for gem polychromatic tourmalines, topaz and beryl. It is situated a the southern side of Mt. Tsinjoarivo, in the central part of the Sahatany Pegmatite Field. It was described by A. Lacroix (1922) under the name "Tompohobohitra" or "Tompobohitra" by Guigues (1954).
