The evolving mosaic of tectonic plates across the surface of the Earth sets boundary
conditions for the evolution of biotic and abiotic processes and helps shape the dynamics of …

Deep crustal production of hydrogen (H2) is a potential source of primary energy if
recoverable accumulations in geological formations are sufficiently large. We report direct …

Deep-sea hydrothermal systems at slow/ultraslow-spreading mid-ocean ridges are often
located within ultramafic rocks that are part of oceanic core complexes. These complexes …

Native hydrogen (H2) may represent a new carbon free‐energy resource, but to date there is
no specific exploration guide to target H2‐fertile geological settings. Here, we present the …

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 …

Mantle serpentinization influences the rheology of altered peridotites and the global fluxes of
energy and volatiles, the generation of seafloor and sub-seafloor chemolithotrophic life, and …

Hydrogen is a key energy carrier that could play a crucial role in the transition to a low-
carbon economy. Hydrogen-related technologies are considered flexible solutions to …

The Samail Ophiolite in Oman, the largest exposed body of ultramafic rocks at the Earth's
surface, produces a continuous flux of hydrogen through low-temperature water/rock …

Plume magmatism and continental breakup led to the opening of the northeast Atlantic
Ocean during the globally warm early Cenozoic. This warmth culminated in a transient (170 …

Methane (CH4) is a critical but overlooked component in the study of the deep carbon cycle.
Abiotic CH4 produced by serpentinization of ultramafic rocks has received extensive …
