Over the last decades, numerous studies have emphasized the role of serpentinites in the
subduction zone geodynamics. Their presence and role in subduction environments are …

Global data for measured Fe 2 O 3/FeO ratios and Cu contents in unaltered volcanic and
intrusive arc rocks indicate that, on average, they are slightly more oxidized than other …

Experiment and observation have established the centrality of oxygen fugacity (f O 2) to
determining the course of igneous differentiation, and so the development and application of …

Hydrothermal circulation and alteration at mid-ocean ridges and ridge flanks have a key role
in regulating seawater chemistry and global chemical fluxes, and support diverse …

At plate boundaries, where deformation is localized along centimetre-to kilometre-scale
shear zones, the influence of serpentinite on tectonic processes is linked to its unique …

A series of laboratory experiments were conducted to examine how partitioning of Fe among
solid reaction products and rates of H 2 generation vary as a function of temperature during …

Serpentinization of mantle peridotite generates molecular hydrogen that can be exploited by
microorganisms to gain metabolic energy; however, the mechanisms that control hydrogen …

Serpentinization involves the hydrolysis and transformation of primary ferromagnesian
minerals such as olivine ((Mg, Fe) 2SiO4) and pyroxenes ((Mg, Fe) SiO3) to produce H2-rich …

High-pressure dehydration of serpentinite during subduction generates fluids that flux and
melt the overlying mantle wedge, forming primary arc basalts. These basalts are …

Abstract Reduced (H 2-and CH 4-rich) and hyperalkaline fluids are products of subsurface
reactions accompanying serpentinization of ultramafic rocks. H 2 and CH 4 produced during …
