Riebeckite from
Mont'Orfano (Montorfano), Mergozzo, Verbano-Cusio-Ossola Province, Piedmont, Italy


Locality type:Mountain
Classification
Species:Riebeckite
Formula:◻Na2(Fe32+Fe23+)Si8O22(OH)2
Comments:The information on the presence of riebeckite in Mont'Orphano granite, probably due to erroneuos interpretations of the original literature, is unfounded. In Palache et al. (1951) the presence of parisite at Mont'Orfano is erroneously reported from veinlets in riebeckite-granite. Mont'Orfano granite does not contain riebeckite and, obviously, the name riebeckite does not appear in the original literature.
Confirmation
