Orpiment from
Jas Roux, La Chapelle-en-Valgaudemar, Gap, Hautes-Alpes, Provence-Alpes-Côte d'Azur, France


Locality type:Deposit
Classification
Species:Orpiment
Formula:As2S3
Comments:According to J. Mantienne, who first mentioned the mineral, orpiment was never analyzed. There are thick yellow gemmy plates of analysed Wakabayashilite that are easiliy misidentifified as orpiment Vincent Bourgoin commented:
'Orpiment is a mineral highly questionable to Jas Roux because it has never been analyzed.
It is cited in the BRGM inventory and by Mantienne without having ever been the subject of analysis (personal confirmation that I had from M. Mantienne who did his thesis on this deposit).
Some wakabayashilite plates are so thick and gemmy that they can sometimes make you think of the orpiment."
