In olivine, the −4 charge of each silica tetrahedron is balanced by two divalent (i.e., +2) iron or magnesium cations. Olivine can be either Mg 2 SiO 4 or Fe 2 SiO 4, or some combination of the two (Mg,Fe) 2 SiO 4. The divalent cations of magnesium and iron are quite close in radius (0.73 versus 0.62 angstroms [1]). Because of this size ...Web
