Fayalite | mineral | Britannica
Small amounts of fayalite are present in many volcanic rocks in which sodium is more common than potassium. The forsterite-fayalite minerals also occur in dolomitic limestones, marbles, and metamorphosed iron-rich sediments. These minerals are relatively infusible, not melting below 1,500 °C (2,700 °F), and are sometimes used in…

Olivine: The mineral Olivine, peridot information and …
Olivine is not scientifically classified by the IMA as an individual mineral species, but is rather recognized as a mineral group with the Forsterite and Fayalite end members. Fayalite and Forsterite create a solid solution series, and most specimens identified as Olivine fall somewhere in between this series, almost always leaning more towards Forsterite with a greater content of magnesium.
Fayalite | Scientific
These slags are termed fayalitic slags and they consist of wustite (FeO), fayalite (Fe 2 SiO 4) and glass-phase (amorphous silicates) in various concentrations. Three solidification-types were described and correlated with the microstructures and the FeO-SiO 2 -CaO 2 phase diagram.During the 19 th century steel was produced in puddling furnaces by remelting iron products from Eisenerz.
What are L Chondrites – Secondary Type of Meteorite
As for the characteristics of the L chondrite, it contains fayalite of about 25 mol %. It also contains about 5 to 10 % of nickel, which is observed as a metal. Thus, these types of meteorites are somewhat magnetic, although not as powerful as the H chondrites.
Fayalite
Fayalite is a extremely rare member of the Olivine group of minerals that includes Dunilite, Fayalite, Forsterite and Peridot (Olivine)although Peridot is not recognized as a mineral that is split. Fayalite and Forsterite are simply known as Olivine. Fayalite is the iron ...
Fayalite
Fayalite in igneous rocks most often has more or less similar habits. Of greater diversity are the minerals that form by rapid crystallization or quenching of melts at shallow depths or at the surface (komatiites, picrite basalts, picrite sills, and other mafic and ultramafic lavas) ( Deer et al., 1982 ).
