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.

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 ...

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 ...

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.

Subduction initiation at relic arcs [PDF]
Geophysical Research Letters, 2015 AbstractAlthough 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).

The location of compression-induced subduction initiation controlled by structural versus thermal inheritance [PDF]
Communications Earth & EnvironmentSubduction initiation is a pivotal process in the Wilson cycle, yet its mechanisms remain elusive. Using 3D coupled thermo-mechanical and surface processes models, we investigated how the duration of the plate motion reversal from rifting to plate ...
