Finding natural $$\hbox {H}_{2}$$ generation zones in Midcontinent Rift in the U.S. by identifying the geophysical signatures of a serpentinization system [PDF]

Scientific Reports
Hydrogen is gaining attention as an energy source for its zero CO2 emission. Hydrogen may be manufactured by breaking down water using solar and wind energy. However, the high cost of manufactured hydrogen makes it uneconomical.

Serpentinization as the source of energy, electrons, organics, catalysts, nutrients and pH gradients for the origin of LUCA and life [PDF]

Frontiers in Microbiology, 2023
Serpentinization in hydrothermal vents is central to some autotrophic theories for the origin of life because it generates compartments, reductants, catalysts and gradients.

Global rates of mantle serpentinization and H2 production at oceanic transform faults in 3‐D geodynamic models

Geophysical Research Letters, 2017
Previous studies have estimated that mantle serpentinization reactions generate H2 at a rate of 1010–1012 mol/yr along the global mid‐ocean ridge (MOR) system.

Successive phases of serpentinization and carbonation recorded in the Sivas ophiolite (Turkey), from oceanic crust accretion to post-obduction alteration

BSGF - Earth Sciences Bulletin, 2022
The ophiolite of Sivas (Turkey) was studied in order to define the chronology of different alteration events related to a series of serpentinization and carbonation episodes. Six samples were investigated, representative of different types of ophicalcite

δ60Ni and δ13C Composition of Serpentinites and Carbonates of the Tekirova Ophiolite, Turkey, and Meatiq Ophiolite, Egypt

Frontiers in Earth Science, 2021
Nickel isotope fractionation patterns in continental ultramafic environments generally show a depletion of δ60Ni in weathered rocks and an enrichment in bedrock samples.

Dataset for H2, CH4 and organic compounds formation during experimental serpentinization

Geoscience Data Journal, 2021
Serpentinization refers to the alteration of ultramafic rocks that produces serpentines and secondary (hydr)oxides under hydrothermal conditions. Serpentinization can generate H2, which in turn can potentially reduce CO/CO2 and produce organic molecules ...

Deducing Mineralogy of Serpentinized and Carbonated Ultramafic Rocks Using Physical Properties With Implications for Carbon Sequestration and Subduction Zone Dynamics

Geochemistry, Geophysics, Geosystems, 2021
Serpentinization of ultramafic rocks is fundamental to modern plate tectonics and for volatile (re‐)cycling into the mantle and magmatic arcs. Serpentinites are also highly reactive with CO2 such that they are prime targets for carbon sequestration ...
