Hydrocarbon formation by reactions of graphite with water-containing minerals under high pressure and high temperature

Study on hydrocarbon formation by reaction of graphite, serpentine and olivine and reaction of graphite and biotite was carried out under high pressure and high temperature using a diamond anvil cell apparatus. Gas chromatographic analysis results indicate that both reactions generate methane-dominated hydrocarbon, which means these reactions are likely significant ways of abiogenetic hydrocarbon formation in the deep earth.
