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

Classification
Species:Parisite-(Ce)
Comments:Originally described as yellowish hexagonal crystals occurring in a crust, consisting of chlorite, stilbite, chabazite, fluorite, and pyrite, or perched on quartz crystals. On the basis of chemical and physical investigations, the mineral was classified as parisite (Tacconi, 1905). The material of the original description is no more available for modern investigations. According to Gramaccioli (1975), it should be attributable to synchysite-(Ce).

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
Validity:Unconfirmed/Questioned
