Subduction Zone Obliquity Dictates Global Trench‐Parallel Inner Forearc Deformation

AGU Advances
Although 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.

Onset of double subduction controls plate motion reorganisation

Nature Communications
Face-to-face double subduction systems, in which two oceanic plates subduct toward each other, are essential elements of plate tectonics. Two subduction zones in such systems are typically uneven in age and their spatially and temporally variable ...

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

Terra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

Ophiolites in the Central Asian Orogenic Belt record Cambrian subduction initiation processes

Communications Earth & Environment
Subduction initiation remains elusive because no present example exists. Ophiolites formed over nascent subduction zones in the past provide the key to constraining the processes of subduction initiation.

Subduction zone geochemistry

Geoscience Frontiers, 2019
Abstract Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity. However, crustal signatures in the mantle source of basaltic rocks above subduction zones were primarily incorporated in the form of liquid rather than solid phases. The physicochemical property of liquid phases is determined by the dehydration behavior of

Mantle Dynamics in the Mediterranean and Plate Motion of the Adriatic Microplate: Insights From 3D Thermomechanical Modeling

Geochemistry, Geophysics, Geosystems
The motion of the Adriatic microplate is thought to be highly sensitive to the surrounding subduction zones and the convergence of Africa and Eurasia. However, our understanding of the mantle dynamics in the Mediterranean region and its effect on plate ...

Breaking boundaries in subduction science

Nature Communications, 2020
Subduction is the primary driver of plate tectonics, yet we still do not fully understand how subduction zones initiate or the budgets of life-supporting elements recycled via subduction.

Overriding Plate Thickness as a Controlling Factor for Trench Retreat Rates in Narrow Subduction Zones

Geochemistry, Geophysics, Geosystems
Slab width is a significant factor in controlling subduction zone dynamics, particularly the retreat velocities, which tend to decrease with wider slabs.

Mantle Flow and Anisotropy in Subduction Zones: Modeling and Clustering of Olivine Textures

Geochemistry, Geophysics, Geosystems
The mantle near Earth's subduction zones endures intense deformation that generates anisotropic rock textures. These textures can be observed seismically and modeled geodynamically, but the complexity of this deformation makes analyses of these textures ...
