Serpentinization: Connecting Geochemistry, Ancient Metabolism and Industrial Hydrogenation
Life, 2018 Rock–water–carbon interactions germane to serpentinization in hydrothermal vents have occurred for over 4 billion years, ever since there was liquid water on Earth. Serpentinization converts iron(II) containing minerals and water to magnetite

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 ...

Water, oceanic fracture zones and the lubrication of subducting plate boundaries - insights from seismicity [PDF]
, 2015 We investigate the relationship between subduction processes and related seismicity for the Lesser Antilles Arc using the Gutenberg-Richter law. This power lawdescribes the earthquakemagnitude distribution, with the gradient of the cumulative magnitude ...

Mantle wedge serpentinization effects on slab dips
Terrestrial, Atmospheric and Oceanic Sciences, 2017 The mechanical coupling between a subducting slab and the overlying mantle wedge is an important factor in controlling the subduction dip angle and the flow in mantel wedge. This paper investigates the role of the amount of mantle serpentinization on the

Fluid‐Mantle Interaction Along the Mariana Convergent Margin
Geochemistry, Geophysics, Geosystems, 2023 Active serpentinite mud volcanoes in the forearc region of the Izu‐Bonin‐Mariana system represent an excellent natural laboratory for studying the geochemical processes along convergent plate margins and the associated forearc. During IODP Expedition 366,

Frontiers in Microbiology, 2023 The demonstration by Ivan Barnes et al. that the serpentinization of fresh Alpine-type ultramafic rocks results in the exhalation of hot alkaline fluids is foundational to the submarine alkaline vent theory (AVT) for life’s emergence to its ‘improbable ...

Carbonate alteration of ophiolitic rocks in the Arabian–Nubian Shield of Egypt: sources and compositions of the carbonating fluid and implications for the formation of Au deposits [PDF]
, 2016 Ultramafic portions of ophiolitic fragments in the Arabian–Nubian Shield (ANS) show pervasive carbonate alteration forming various degrees of carbonated serpentinites and listvenitic rocks.

Serpentinization-Associated Mineral Catalysis of the Protometabolic Formose System
Life, 2023 The formose reaction is a plausible prebiotic chemistry, famed for its production of sugars. In this work, we demonstrate that the Cannizzaro process is the dominant process in the formose reaction under many different conditions, thus necessitating a ...
