A Cenozoic Record of Deep Oceanic Zn Isotopic Composition in Ferromanganese Crusts

M Zhao, N Planavsky, X Wang, Y Zhang… - American Journal of …, 2023 - ajsonline.org
Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

Subduction of oceanic lithosphere in the Alps: Selective and archetypal from (slow-spreading) oceans

P Agard - Earth-Science Reviews, 2021 - Elsevier
The Alps are amongst the best subduction archives in the world, with abundant blueschists
and eclogites preserving fragments of mantle, gabbros, thinned continental margin and …

Oxidising agents in sub-arc mantle melts link slab devolatilisation and arc magmas

A Bénard, K Klimm, AB Woodland, RJ Arculus… - Nature …, 2018 - nature.com
Subduction zone magmas are more oxidised on eruption than those at mid-ocean ridges.
This is attributed either to oxidising components, derived from subducted lithosphere (slab) …

Highly oxidising fluids generated during serpentinite breakdown in subduction zones

B Debret, DA Sverjensky - Scientific reports, 2017 - nature.com
Subduction zones facilitate chemical exchanges between Earth's deep interior and
volcanism that affects habitability of the surface environment. Lavas erupted at subduction …

Serpentinite fluids and slab-melting in the Aleutian arc: Evidence from molybdenum isotopes and boron systematics

E Rojas-Kolomiets, O Jensen, M Bizimis… - Earth and Planetary …, 2023 - Elsevier
Mo isotope compositions have been increasingly used as a source tracer in magmatic
systems. Here, we investigate the relative role of subducting oceanic crust, fluid-rich sources …

Iron isotope systematics in planetary reservoirs

PA Sossi, O Nebel, J Foden - Earth and Planetary Science Letters, 2016 - Elsevier
Iron is the only polyvalent major element, and controls reduction–oxidation (redox) reactions
in a host of geologic processes and reservoirs, from the mineral-to planetary-scale, on Earth …

Molybdenum systematics of subducted crust record reactive fluid flow from underlying slab serpentine dehydration

S Chen, RC Hin, T John, R Brooker, B Bryan… - Nature …, 2019 - nature.com
Fluids liberated from subducting slabs are critical in global geochemical cycles. We
investigate the behaviour of Mo during slab dehydration using two suites of exhumed …

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 …

Oxidation state of arc mantle revealed by partitioning of V, Sc, and Ti between mantle minerals and basaltic melts

J Wang, X Xiong, E Takahashi… - … Research: Solid Earth, 2019 - Wiley Online Library
Whether arc mantle is more oxidized than oceanic mantle is persistently debated. The
behavior of multivalent vanadium (V) is oxygen fugacity (fO2) sensitive, and the ratios of V to …
