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. Here, Clift et al question the evidence for subduction initiation, suggesting that simpler rifting-related processes can more ...

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.

Strike slip motion and the triggering of subduction initiation [PDF]
Frontiers in Earth Science, 2023 Plate tectonic reconstructions of three of the best-defined Cenozoic subduction initiation (SI) events in the western Pacific, Izu-Bonin-Mariana, Vanuatu, and Puysegur subduction zones, show substantial components of strike-slip motion before and during ...

Subduction initiation at passive margins: Numerical modeling [PDF]
Journal of Geophysical Research, 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.

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
