Sellaite from
La Piastra Quarry, Torano quarrying basin, Carrara, Massa-Carrara Province, Tuscany, Italy

Locality type:Quarry
Classification
Species:Sellaite
Formula:MgF2
Comments:The loose transparent crystal studied by Pelloux (1919) is without any doubt sellaite. It contains small inclusions of sulphur, gypsum, and probably anhydrite as at the type locality (Gébroulaz glacier, Savoie, France). According to Orlandi & Criscuolo (2009), the occurrence of sellaite within the Carrara marble cavities should be considered questionable. In fact, there are no evidences that the sample studied by Pelloux (1919) had been actually collected at Carrara. A possible fraud in the provenance of the studied material (Gébroulaz and not Carrara) could not be excluded.
Confirmation
Validity:Believed Valid
