Complexity of the serpentinization lipidome

, 2022
Energy from serpentinization processes potentially fuelled the origin of life on Earth. Thus, if serpentinite-impacted sites facilitate microbial habitability, it is important to understand the source and retention of biological signatures in them ...

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 ...

Serpentinization-Driven H2 Production From Continental Break-Up to Mid-Ocean Ridge Spreading: Unexpected High Rates at the West Iberia Margin

Frontiers in Earth Science, 2021
Molecular hydrogen (H2) released during serpentinization of mantle rocks is one of the main fuels for chemosynthetic life. Processes of H2 production at slow-spreading mid-ocean ridges (MORs) have received much attention in the past. Less well understood

Hydrothermal remobilization platinum group elements and their secondary minerals in chromitite deposits of the Eastern Sayan ophiolites (Russia) [PDF]

E3S Web of Conferences, 2019
Serpentinization is an important post-magmatic process in spreading and subducted zones. This process is the cause of the remobilization and redistribution of highly mobile elements, platinum group elements (PGE) and base metals. Secondary platinum group

Mantle hydration along outer-rise faults inferred from serpentinite permeability

Scientific Reports, 2017
Recent geophysical surveys indicate that hydration (serpentinization) of oceanic mantle is related to outer-rise faulting prior to subduction. The serpentinization of oceanic mantle influences the generation of intermediate-depth earthquakes and ...

Carbonation and serpentinization of diopsidite in the Altun Mountains, NW China

Scientific Reports, 2022
Mineral carbonation of mafic–ultramafic rocks has been highlighted as a promising way for permanent carbon capture and storage. Carbonatization involves the release of Ca, Mg and Fe from silicate minerals by dissolution and reaction in the aqueous phase ...

Serpentinization in the Thermal Evolution of Icy Kuiper Belt Objects in the Early Solar System [PDF]

, 2022
Here we present an improved algorithm to model the serpentinization process in planetesimals in the early solar system. Although it is hypothesized that serpentinization-like reactions played an important role in the thermal evolution of planetesimals ...

Interrelation between rifting, faulting, sedimentation, and mantle serpentinization during continental margin formation—including examples from the Norwegian Sea

Geochemistry, Geophysics, Geosystems, 2013
The conditions permitting mantle serpentinization during continental rifting are explored within 2‐D thermotectonostratigraphic basin models, which track the rheological evolution of the continental crust, account for sediment blanketing effects, and ...
