Subduction initiation at relic arcs [PDF]
Geophysical Research Letters, 2015 Although plate tectonics is well established, how a new subduction zone initiates remains controversial. Based on plate reconstruction and recent ocean drilling within the Izu-Bonin-Mariana, we advance a new geodynamic model of subduction initiation (SI).

Differentiating induced versus spontaneous subduction initiation using thermomechanical models and metamorphic soles [PDF]
Nature Communications, 2021 The mechanism of subduction initiation is a key to modern plate tectonics. Here, using numerical modeling and geological observations, the authors find that the majority of active and paleo subduction zones with metamorphic soles likely formed during ...

Geosystems and Geoenvironment, 2022 Initiation of new subduction zones is an integral part of Earth's plate tectonics regime. It is generally accepted that the negative buoyancy of sufficiently old oceanic lithosphere provides the primary driving force for subduction initiation.

Subduction initiation triggered the Caribbean large igneous province [PDF]
Nature Communications, 2023 Using a large-scale 3D geodynamic model, the authors show how the transfer of subduction zone from the Pacific to the Atlantic triggered the formation of a mantle plume at the origin of the Cretaceous Caribbean Large Igneous province.

Subduction Initiation by Plume‐Plateau Interaction: Insights From Numerical Models [PDF]
Geochemistry, Geophysics, Geosystems, 2020 It has recently been demonstrated that the interaction of a mantle plume with sufficiently old oceanic lithosphere can initiate subduction. However, the existence of large lithospheric heterogeneities, such as a buoyant plateau, in proximity to a rising ...

Plume‐Induced Subduction Initiation: Single‐Slab or Multi‐Slab Subduction? [PDF]
Geochemistry, Geophysics, Geosystems, 2020 Initiation of subduction following the impingement of a hot buoyant mantle plume is one of the few scenarios that allow breaking the lithosphere and recycling a stagnant lid without requiring any preexisting weak zones.

Reply to ‘Evidence for simple volcanic rifting not complex subduction initiation in the Laxmi Basin’ [PDF]
Nature Communications, 2020 Recently, Pandey et al. proposed relict subduction initiation occurred along a passive margin in the northwest Indian Ocean, however, Clift et al. questioned their evidence for subduction initiation, suggesting that simpler rifting-related processes ...

Subduction Duration and Slab Dip [PDF]
Geochemistry, Geophysics, Geosystems, 2020 The dip angles of slabs are among the clearest characteristics of subduction zones, but the factors that control them remain obscure. Here, slab dip angles and subduction parameters, including subduction duration, the nature of the overriding plate, slab

Rapid subduction initiation and magmatism in the Western Pacific driven by internal vertical forces [PDF]
Nature Communications, 2020 The magmatic progression produced during the initiation of the Izu-Bonin-Marianas subduction zone took place rapidly over 1 million years, but it has been unclear why.
