An unnamed quarry "1 km from Ihosy" (Nicollet 1990). This probably refers to the quarry along the RN 7 about 1 km North of the town of Ihosy. This quarry has earlier been referred to as "the cordierite locality" ("Le gisement de cordiérite"). A sillimanite- and cordierite-bearing gneissic rock in the Ihosy formation is quarried here for pavement and residential construction.
5 valid minerals.
