Forsterite (Mg2SiO4; 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 … See more Pure forsterite is composed of magnesium, oxygen and silicon. The chemical formula is Mg2SiO4. Forsterite, fayalite (Fe2SiO4) and tephroite (Mn2SiO4) are the end-members of the olivine solid solution series; … See more Forsterite is mainly composed of the anion SiO4 and the cation Mg in a molar ratio 1:2. Silicon is the central atom in the SiO4 anion. Each oxygen … See more Forsterite is being currently studied as a potential biomaterial for implants owing to its superior mechanical properties. See more Forsterite-rich olivine is the most abundant mineral in the mantle above a depth of about 400 km (250 mi); pyroxenes are also important minerals … See more Forsterite was first described in 1824 for an occurrence at Mount Somma, Vesuvius, Italy.
