One of the skarn outcrop localities in this area was referred to in 1998 by some mineral dealers in Antsirabe as Ambatonigaby, but this spelling is uncertain, other dealers gave the name Ambatondragaby (= At Gaby's rock) which seems more likely (K.E. Larsen commentary 2012).
Minerals are also found at the exocontacts with pegmatites in the area.
