The redox budget of subduction zones
KA Evans - Earth-Science Reviews, 2012 - Elsevier
Elements that can occur in more than one valence state, such as Fe, C and S, play an
important role in Earth's systems at all levels, and can drive planetary evolution as they cycle …

Brines at high pressure and temperature: thermodynamic, petrologic and geochemical effects
A number of observations point to the participation of brines in high-grade metamorphic
processes. These include findings of alkali and alkaline-earth halides as daughter crystals in …

Deserpentinization in subduction zones as a source of oxidation in arcs: A reality check
KA Evans, BR Frost - Journal of Petrology, 2020 - ieeexplore.ieee.org
Previous studies have concluded that dehydration of serpentinites in subduction zones
produces oxidizing fluids that are the cause of oxidized arc magmas. Here, observations of …

The relationship between subduction zone redox budget and arc magma fertility
A number of lines of evidence point to a causal link between oxidised slab-derived fluids,
oxidised sub-arc mantle, and the formation of economic concentrations of metals such as Cu …

COHS fluids released by oceanic serpentinite in subduction zones: Implications for arc-magma oxidation
Subducted oceanic serpentinite carries H 2 O, ferric iron, carbon and sulfur into the
subduction zone, where they are stepwise released during dehydration. These COHS fluids …

Tracking Fe mobility and Fe speciation in subduction zone fluids at the slab-mantle interface in a subduction channel: A tale of whiteschist from the Western Alps
Fluids released by subducting slabs are important to the geochemical evolution of Earth's
