Molecular hydrogen in surface and subsurface natural gases: Abundance, origins and ideas for deliberate exploration
AV Milkov - Earth-Science Reviews, 2022 - Elsevier
Geologic molecular hydrogen (H 2) occurs in the subsurface and vents and seeps at the
surface. However, this valuable natural resource is under-utilized in the economy because …

Subduction hides high-pressure sources of energy that may feed the deep subsurface biosphere
Geological sources of H2 and abiotic CH4 have had a critical role in the evolution of our
planet and the development of life and sustainability of the deep subsurface biosphere. Yet …

High-pressure serpentinization and abiotic methane formation in metaperidotite from the Appalachian subduction, northern Vermont
Serpentinization is the process of hydroxylation of olivine-rich ultramafic rocks to produce
minerals such as serpentine, brucite and magnetite. This process is commonly accompanied …
