Cl stable isotopes in subduction zones
, 2007 Chlorine stable isotope ratios (δ 37Cl) in pore fluids, serpentines, and solid samples from three subduction zones, the Nankai Trough (Ocean Drilling Program Legs 131 and 190), Costa Rica (ODP Legs 170 and 205), and Mariana Forearc (ODP Leg 195) provide ...

A Phase‐Field Model for Quasi‐Dynamic Rupture Nucleation and Propagation of In‐Plane Faults
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Computational modeling of faulting processes is an essential tool for understanding earthquake mechanics but remains challenging due to the structural and material complexities of fault zones. The phase‐field method has recently enabled unified modeling of fault propagation and off‐fault damage within a fracture‐mechanics‐based framework ...

Nature Communications, 2018 Variations in seismicity are observed at subduction zones, but the oceanic sides remain poorly resolved. Here, the author presents tomographic results of the Cascadia subduction system demonstrating that there are significant variations of the oceanic ...

Remote Sensing in Ecology and Conservation, EarlyView.Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Horizontal mantle flow controls subduction dynamics
Scientific Reports, 2017 It is generally accepted that subduction is driven by downgoing-plate negative buoyancy. Yet plate age –the main control on buoyancy– exhibits little correlation with most of the present-day subduction velocities and slab dips. “West”-directed subduction

Geophysical Research Letters, 2022 It is not rare to observe subduction zones transferring into collision zones. However, it is poorly understood the lateral variation in flexural deformation.

Science Education, EarlyView.ABSTRACT Opening space for students to help shape knowledge building practices in the classroom—that is, epistemic agency—is necessary to achieve a variety of goals held by the science education community. As such, many scholars have explored how students might be positioned with, perceive, and take up epistemic agency.

Subduction Zone Obliquity Dictates Global Trench‐Parallel Inner Forearc Deformation
AGU AdvancesAlthough subduction zones are characterized by convergence, the upper plates of subduction zones exhibit a diverse range of deformation styles that are often inconsistent with regional convergence.
