The gas-phase reactions required to overcome kinetic barriers to CH4 production will be inhibited at greater crustal thicknesses.
“In addition, the gas-phase reactions required to overcome kinetic barriers to CH4 production will be inhibited at greater crustal thicknesses (44).”

Hydrothermal alteration of crustal mafic rocks (serpentinization) produces H2, followed by Fischer-Tropsch type (FTT) synthesis.
“A much discussed scenario for abiotic methane generation is through hydrothermal alteration of crustal mafic rocks (serpentinization), which produces H2, followed by Fischer-Tropsch type (FTT) synthesis.”

Evidence from field studies suggests that abiotic methane is generated in some hydrothermal systems.
“Although evidence from field studies suggests that abiotic methane is generated in some hydrothermal systems (44, 50), laboratory experiments typically find very low methane yields from FTT synthesis from olivine.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
