Orpiment from
Ravaccione quarries (Ravaccione Quarry; Torrione Quarry; Tecchione Quarry), Torano quarrying basin, Carrara, Massa-Carrara Province, Tuscany, Italy

Locality type:Quarry
Classification
Species:Orpiment
Formula:As2S3
Comments:Mentioned by Giampaoli (1905) and D'Achiardi (1905) as an alteration product of realgar, in the form of thin yellow scales and orange-yellow spots on the former. The yellow to yellow-orange mineral mentioned by these two authors, and later by other authors, is actually pararealgar (orpiment cannot derive from the alteration of realgar, that usually alters into pararealgar). Consequently, the occurrence of orpiment from the marble cavities of this locality has to be considered as questionable (Biagioni et al., 2019).

Validity:Unconfirmed/Questioned
