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 ...

Hot versus cold subduction initiation. [PDF]
Natl Sci RevInitiation of a new subduction zone could act in two different ways, forming either a hot or cold incipient subduction channel with contrasting geological records.

Boron isotopes in boninites document rapid changes in slab inputs during subduction initiation [PDF]
Nature Communications, 2022 The geochemical record of subduction initiation is still not well understood, despite >50 years of study. Here, the authors use boron isotopes in Izu-Bonin boninites to document rapid changes in slab inputs to melting at the start of subduction, related ...

Tectonic and climatic implications of the Aleutian Arc initiation ≥56 million years ago [PDF]
Nature CommunicationsThe timing and origin of Aleutian subduction initiation remain poorly constrained, yet they are central to understanding late Paleocene to early Eocene plate tectonic reorganization in the Pacific and its possible climatic consequences.

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).

Ophiolites in the Central Asian Orogenic Belt record Cambrian subduction initiation processes
Communications Earth & EnvironmentSubduction initiation remains elusive because no present example exists. Ophiolites formed over nascent subduction zones in the past provide the key to constraining the processes of subduction initiation.

Horizontally forced initiation of the Izu-Bonin-Mariana subduction zone
Communications Earth & EnvironmentThe sparsity of a direct record for the moment of subduction zone initiation has led to various models describing the infancy and evolution of modern oceanic subduction systems.

Subduction Initiation at Passive Margins: Numerical Modeling [PDF]
Journal of Geophysical Research: Solid Earth, 2010 Subduction is a key process for terrestrial plate tectonics, but its initiation is still not entirely understood. In particular, despite the abundance of both passive and active continental margins on Earth, no obvious cases of transition between them have been identified so far.

Do microcontinents nucleate subduction initiation?
, 2022 Subduction initiation is a pivotal process in plate tectonics. Models of subduction initiation include the collapse of passive margins, oceanic transform faults, inversion of oceanic core complexes, and ridge failure, but have ignored the potential effects of continental crust relics within the oceanic crust.

A transdisciplinary and community-driven database to unravel subduction zone initiation [PDF]
Nature 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.
