Production of abiotic or biogenic hydrocarbons on rock particles in the presence of H2O and carbon compounds

Young Sang Cho, In‐Hwan Oh, Ju Hee Kim, Jae Ik Kim et autres

Abiotic H 2 and hydrocarbons are found in fluids discharged from ultramafic-hosted hydrothermal vents. Beneath the hydrothermal vents, abiotic H 2 and hydrocarbons can be formed by serpentinization reactions and Fischer–Tropsch-type hydrocarbon-forming reactions, respectively, over ultramafic rocks. However, the source rocks that …
