Tectonic significance of serpentinites

S Guillot, S Schwartz, B Reynard, P Agard, C Prigent - Tectonophysics, 2015 - Elsevier
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 …

Variability of subducting slab morphologies in the mantle transition zone: Insight from petrological-thermomechanical modeling

ZH Li, T Gerya, JAD Connolly - Earth-Science Reviews, 2019 - Elsevier
Variable morphologies of subducting slabs are observed in tomographic images of the
mantle transition zone (MTZ), where slabs appear to stagnate in the MTZ or enter the lower …

A metamorphic origin for Europa's ocean

M Melwani Daswani, SD Vance… - Geophysical …, 2021 - Wiley Online Library

Subducting serpentinites release reduced, not oxidized, aqueous fluids

F Piccoli, J Hermann, T Pettke, JAD Connolly… - Scientific Reports, 2019 - nature.com
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 …

Mantle wedge oxidation from deserpentinization modulated by sediment-derived fluids

JA Padrón-Navarta, V López Sánchez-Vizcaíno… - Nature …, 2023 - nature.com
High-pressure dehydration of serpentinite during subduction generates fluids that flux and
