WebOlivine forms the carbonate mineral magnesite via reactions such as Mg2SiO4 (olivine) + 2 CO2 (from gas or fluid) = 2MgCO3 (magnesite) + SiO2 (quartz) Olivine is abundant, has more magnesium than silicon, and reacts readily because it is far from equilibrium with the atmosphere and surface waters. Webolivine , is composed of isolated tetrahedra bonded to iron and/or magnesium ions. 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.
