Forsterite

Silicate Minerals

Forsterite (Mg2SiO4, also known as white olivine) is the magnesium-rich end member of the olivine solid solution series and is isomorphous with the iron-rich end member, fayalite. It crystallizes in the orthorhombic system and is associated with igneous and metamorphic rocks, and it has been found in meteorites, in cometary dust returned by the Stardust probe in 2005, and as tiny crystals in the dusty gas clouds around a forming star. Peridot is the gemstone variety of forsterite olivine. In this atlas it is the mineral species that the gemstone peridot records.
