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

A transdisciplinary and community-driven database to unravel subduction zone initiation

open access: yesNature Communications, 2020
Despite numerous advances in our understanding of subduction since the theory of plate tectonics was established, the mechanisms of subduction zone initiation remain highly controversial.

Co-Evolution of Parallel Triple Subduction Systems in the New Guinea Region: A Systematic Numerical Study

open access: yesFrontiers in Earth Science, 2022
A specific configuration of the global subduction system is the parallel triple subduction. The widely accepted example of parallel triple subduction is the New Guinea region, including a northward dip at the New Britain Trench (NBT), a southward dip at ...

The Norfolk Ridge: A Proximal Record of the Tonga‐Kermadec Subduction Initiation

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Norfolk Ridge bounds the northeastern edge of the continent of Zealandia and is proximal to where Cenozoic Tonga‐Kermadec subduction initiation occurred.

Kinematic evolution of the Southern Andean orogenic arc [PDF]

open access: yes, 2016
In the classic book ‘Origin of Continents and Oceans’ written 40 years before the plate tectonics theory was postulated, Alfred Wegener suggested that map-view curvatures in orogenic belts were the result of the motion of continents.
