Locality
Mania, Island of Madagascar

A good, rich specimen with crystal grains of Humite from 1 to 4mm in white Calcite (marble?). This was an old Southwest Scientific Company specimen, which placed the locality at Mania, Madagascar. But Mania is a river. I couldn't reconcile this locality with any other locality for Humite in Madagascar. As such, I stuck with the labeled locality in hopes that somebody out there has any information. Mindat only list one locality in Madagascar.
