==Composition== [[File:Forsterite orange - Ochtendung, Eifel, Germany.jpg|thumb|left|Orange forsterite with a portion of tephroite]] Pure forsterite is composed of magnesium, oxygen and silicon. The chemical formula is Mg<sub>2</sub>SiO<sub>4</sub>. Forsterite, [[fayalite]] (Fe<sub>2</sub>SiO<sub>4</sub>) and [[tephroite]] (Mn<sub>2</sub>SiO<sub>4</sub>) are the end-members of the olivine solid solution series; other elements such as Ni and Ca substitute for Fe and Mg in olivine, but only in minor proportions in natural occurrences. Other minerals such as [[monticellite]] (CaMgSiO<sub>4</sub>), an uncommon calcium-rich mineral, share the olivine structure, but solid solution between olivine and these other minerals is limited. Monticellite is found in [[Contact metamorphism|contact metamorphosed]] dolomites.<ref name=Klein/>
