A record of spontaneous subduction initiation in the Izu–Bonin–Mariana arc [PDF]

open access: yes, 2015
The initiation of tectonic plate subduction into the mantle is poorly understood. If subduction is induced by the push of a distant mid-ocean ridge or subducted slab pull, we expect compression and uplift of the overriding plate. In contrast, spontaneous

Slow subduction initiation drives fast mantle upwelling and lithosphere formation [PDF]

open access: yes, 2021
International audienceSubduction zones are crucial features of Earth"s plate tectonics, yet subduction initiation remains enigmatic and controversial. Herein, we reappraise the timing of formation of the first fragments detached from the leading edge of ...

Dynamics of intraoceanic subduction initiation: 1. Oceanic detachment fault inversion and the formation of supra-subduction zone ophiolites [PDF]

open access: yes, 2015
Subduction initiation is a critical link in the plate tectonic cycle. Intraoceanic subduction zones can form along transform faults and fracture zones, but how subduction nucleates parallel to mid-ocean ridges, as in e.g., the Neotethys Ocean during the ...

Effects of rheological stratification and elasticity of lithosphere on subduction initiation

open access: yesFrontiers in Earth Science, 2022
The breaking and bending of rigid and elastic lithosphere was probably essential for the initiation of plate subduction, although how this occurred is still poorly understood.

Analogue modelling of the initiation of subduction [PDF]

open access: yesGeophysical Journal International, 2005
SUMMARY We report the results of experiments on the initiation of subduction, using stratified analogue models in a large centrifuge, where the experiments are driven only by the enhanced gravity of the centrifuge without the effect of external lateral stresses. The scaled density of the stratified components resembles that of the asthenosphere and the

Dynamics of intraoceanic subduction initiation: 2. Suprasubduction zone ophiolite formation and metamorphic sole exhumation in context of absolute plate motions [PDF]

open access: yes, 2015
Analyzing subduction initiation is key for understanding the coupling between plate tectonics and the underlying mantle. Here we focus on suprasubduction zone (SSZ) ophiolites and how their formation links to intraoceanic subduction initiation in an ...

Strain localization mechanisms for subduction initiation at passive margins [PDF]

open access: yes, 2020
International audienceIt is widely accepted that subduction initiation at modern Earth passive margin systems critically depends on the buoyancy and strength of the oceanic lithosphere and requires failure of the load-bearing crustal and mantle layers ...

Impact of upper mantle convection on lithosphere hyperextension and subsequent horizontally forced subduction initiation [PDF]

open access: yesSolid Earth, 2020
Many plate tectonic processes, such as subduction initiation, are embedded in long-term (>100 Myr) geodynamic cycles often involving subsequent phases of extension, cooling without plate deformation and convergence. However, the impact of upper mantle
