Member of:Triphylite Group
Name:From FERRI- for trivalent iron (ferric iron) and Sicklerite in allusion to its composition as the ferric iron end member of the series with sicklerite.


Ferrisicklerite-Sicklerite Series

Occurs only as an alteration product of Triphylite and Lithiophilite, commonly as rims around partly altered masses or crystals of the latter species.
