Name:Named by Gmelin in 1840 for the type locality, Faial Island (Fayal Island), Azores District (Azores Islands), Portugal.


Olivine Group. Fayalite-Forsterite Series, and the Fayalite-Tephroite Series. The Fe2+ analogue of Forsterite, Tephroite, and Calcio-Olivine.

Very rare in nature, but common in man-made (metallurgy) iron slags.
