Forearc Variability and the Geochemical Diversity of Suprasubduction Zone Ophiolites: Insights From the Leka Ophiolite Complex, Norway

Geochemistry, Geophysics, Geosystems
New whole‐rock major and trace element geochemistry from the Leka Ophiolite Complex in Norway is presented and compared to the geochemical evolution and proposed tectonomagmatic processes recorded in the Izu‐Bonin‐Mariana system.

Seamount Subduction and Earthquakes [PDF]

Oceanography, 2010
Seamounts are ubiquitous features of the seafloor that form part of the fabric of oceanic crust. When a seamount enters a subduction zone, it has a major affect on forearc morphology, the uplift history of the island arc, and the structure of the ...

Morphology and tectonics of the Andaman Forearc, northeastern Indian Ocean [PDF]

, 2010
The Andaman Sea has developed as the result of highly oblique subduction at the western Sunda Trench, leading to partitioning of convergence into trench-perpendicular and trench-parallel components and the formation of a northward-moving sliver plate to ...

Modeling the absolute stress field in the forearc in the northeast Japan region before and after the 2011 Tohoku earthquake

Progress in Earth and Planetary Science
After the 2011 Tohoku earthquake, the dominant type of focal mechanism in the offshore forearc in Northeast Japan changed dramatically from reverse faulting to normal faulting.

Emergent Feedbacks Between Progressive Serpentinization, Interface Weakening, and Subduction Rates

Geochemistry, Geophysics, Geosystems
During subduction, the downgoing oceanic crust is exposed to high temperatures in the mantle wedge, causing volatile‐bearing minerals to break down and release hydrous fluids into the forearc.

Activity of crustal faults and the Xolapa sliver motion in Guerrero–Oaxaca forearc of Mexico, from seismic data

Earth, Planets and Space, 2019
Oblique convergent margins often host forearc slivers separated by the subduction interface and a trench parallel strike-slip fault system in the overriding plate.

Ridge collision sculpts forearc segmentation along the eastern Nankai Trough

Communications Earth & Environment
Large earthquakes and tsunamis are major hazards at subduction zones, where segmentation governs rupture extent and magnitude. However, the mechanisms that define segment boundaries remain unclear.

Dynamic Evolution of Forearc Subsidence Controlled by Slab Geometry

Several subduction zones worldwide present an enigmatic forearc topography and strain characterized by extension at a forearc ridge near the trench and shortening within a forearc valley located between the ridge and the magmatic arc.
