• Fayalite - Wikipedia

    en.wikipedia.org/wiki/Fayalite Fayalite (Fe 2 SiO 4; commonly abbreviated to Fa), also called iron chrysolite, is the iron-rich end-member of the olivine solid-solution series. In common with all minerals in the olivine group, fayalite crystallizes in the orthorhombic system (space group Pbnm) with cell parameters a 4.82 Å, b 10.48 Å and c 6.09 Å.. Fayalite forms solid solution series with the magnesium olivine endmember ...

    www.galleries.com/Fayalite Fayalite is named for the Island of Fayal of the Azores. It is one of two minerals that are simply known as olivine. The other mineral is forsterite. Fayalite is the iron rich member with a pure formula of Fe 2 SiO 4. Forsterite is the magnesium rich member with a pure formula of Mg 2 SiO 4. The two minerals form a series where the iron and magnesium are substitutable for each other without ...

    en.wikipedia.org/wiki/Forsterite Forsterite (Mg 2 SiO 4; commonly abbreviated as Fo; also known as white olivine) is the magnesium-rich end-member of the olivine solid solution series. It is isomorphous with the iron-rich end-member, fayalite.Forsterite crystallizes in the orthorhombic system (space group Pbnm) with cell parameters a 4.75 Å (0.475 nm), b 10.20 Å (1.020 nm) and c 5.98 Å (0.598 nm).
