The estimation of the amount of CH4 produced within olivine-hosted fluid inclusions. Assuming spherical fluid inclusions with a diameter of 10 μm, the amount of CH4 that could be produced by serpentinization without magnetite formation is calculated. The results of two simple reactions are shown; produced brucite is a Fe-free brucite and b Fe-bearing brucite. The number on the lines shows the assumed density of H2O (100–1000 kg/m3)
