The transport of water from subducting crust into the mantle is mainly dictated by the stability
of hydrous minerals in subduction zones. The thermal structure of subduction zones is a key …

The interface between subducting oceanic slabs and the hanging wall is a structurally and
lithologically complex region. Chemically disparate lithologies (sedimentary, mafic and …

Abstract On September 24, 2023, NASA's OSIRIS‐REx mission dropped a capsule to Earth
containing~ 120 g of pristine carbonaceous regolith from Bennu. We describe the delivery …

Geological pathways for the recycling of Earth's surface materials into the mantle are both
driven and obscured by plate tectonics,–. Gauging the extent of this recycling is difficult …

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 …

Submarine hydrothermal sulfide ores occur at mid-ocean ridges, intra-oceanic arcs and in
back-arc basins associated with host rocks of highly variable composition. Pyrite is the …

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) …

The key role of serpentinites in the global cycles of volatiles, halogens and fluid-mobile
elements in oceans and in subduction zones is now ascertained by many studies …

The mechanisms of transfer of crustal material from the subducting slab to the overlying
mantle wedge are still debated. Mélange rocks, formed by mixing of sediments, oceanic …

The observation that primitive arc magmas are more oxidized than mid-ocean-ridge basalts
has led to the paradigm that slab-derived fluids carry SO2 and CO2 that metasomatize and …
