Abiotic methane synthesis and serpentinization in olivine-hosted fluid inclusions

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance Our findings highlight the ubiquitous occurrence of methane (CH4)-rich fluid inclusions in olivine-bearing rocks that, collectively, may constitute one of the largest reservoirs of abiotic CH4 on Earth.

Effect of Fluid Salinity on Reaction Rate and Molecular Hydrogen (H2) Formation During Peridotite Serpentinization at 300°C

Journal of Geophysical Research: Solid Earth, 2023
We conducted hydrothermal experiments at 300°C and at pressure varying from 2.2 to 3.4 kbar to study the effect of fluid salinity on the coupling between molecular hydrogen (H2) formation and olivine serpentinization, where peridotite and olivine with 25–

An Overlooked Natural Hydrogen Evolution Pathway: Ni2+ Boosting H2O Reduction by Fe(OH)2 Oxidation during Low-temperature Serpentinization.

Angewandte Chemie, 2021
Natural hydrogen (H 2 ) has gained considerable attentions as a renewable energy resource to mitigate the globally increasing environmental concerns. Low-temperature serpentinization (< 200 ° C) as a typical water-rock reaction is a major source of the ...

Serpentine

Proceedings of the 2019 CHI Conference on Human Factors in Computing Systems, 2019
We introduce Serpentine, a self-powered sensor that is a reversibly deformable cord capable of sensing a variety of human input. The material properties and structural design of Serpentine allow it to be flexible, twistable, stretchable and squeezable, enabling a broad variety of expressive input modalities.

Theoretical Predictions Versus Environmental Observations on Serpentinization Fluids: Lessons From the Samail Ophiolite in Oman

Journal of Geophysical Research: Solid Earth, 2021
Thermodynamic calculations provide valuable insights into the reactions that drive the profound fluid transformations during serpentinization, where surface fluids are transformed into some of the most reduced and alkaline fluids on Earth.

Mantle serpentinization beneath a failed rift and post-spreading magmatism in the northeastern South China Sea margin

, 2021
The post-spreading magmatic activities in the northeastern South China Sea (SCS) margin are very strong, evidenced by widely distributed high-velocity lower crust (HVLC) and numerous volcanoes.

Thermodynamic constraints on the geochemistry of low-temperature, continental, serpentinization-generated fluids

American Journal of Science, 2020
The hydrous alteration of ultramafic rocks, known as serpentinization, generates fluids that can fuel microbial communities and enable the synthesis of simple organic compounds.
