Subducting volcaniclastic-rich upper crust supplies fluids for shallow megathrust and slow slip

AC Gase, NL Bangs, DM Saffer, S Han, PK Miller… - Science …, 2023 - science.org
Recurring slow slip along near-trench megathrust faults occurs at many subduction zones,
but for unknown reasons, this process is not universal. Fluid overpressures are implicated in …

Serpentinite-derived slab fluids control the oxidation state of the subarc mantle

Y Zhang, E Gazel, GA Gaetani, F Klein - Science Advances, 2021 - science.org
Recent geochemical evidence confirms the oxidized nature of arc magmas, but the
underlying processes that regulate the redox state of the subarc mantle remain yet to be …

Slab dehydration and potassium-lithium recycling in the forearc indicated by potassium and lithium isotope compositions of exhumed metabasites

H Liu, T Yang, YY Xue, J Deng, Y Xiao, H Sun… - … et Cosmochimica Acta, 2023 - Elsevier
Slab dehydration at subduction zones has broad implications for arc magmatism, mantle

Boron isotopes in boninites document rapid changes in slab inputs during subduction initiation

HY Li, X Li, JG Ryan, C Zhang, YG Xu - Nature communications, 2022 - nature.com
How subduction-related magmatism starts at convergent plate margins is still poorly
understood. Here we show that boron isotope variations in early-formed boninites from the …
