    3 Mg 2 SiO 4 + SiO 2 + 4 H 2 O → 2 Mg 3 Si 2 O 5 (OH) 4. When this reaction occurs in the presence of dissolved carbon dioxide (carbonic acid) at temperatures above 500 °C (932 °F) Reaction 2a takes place. Reaction 2a: Olivine + water + carbonic acid → serpentine + magnetite + methane (Fe,Mg) 2 SiO 4 + nH 2 O + CO 2 → Mg 3 Si 2 O 5 (OH ...
