Subduction-driven recycling of continental margin lithosphere [PDF]

open access: yesNature, 2014
[EN]Whereas subduction recycling of oceanic lithosphere is one of the central themes of plate tectonics, the recycling of continental lithosphere appears to be far more complicated and less well understood1.

Geochemistry of continental subduction-zone fluids [PDF]

open access: yesEarth, Planets and Space, 2014
The composition of continental subduction-zone fluids varies dramatically from dilute aqueous solutions at subsolidus conditions to hydrous silicate melts at supersolidus conditions, with variable concentrations of fluid-mobile incompatible trace ...

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical 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.

Continental evolution influenced by relamination of deeply subducted continental crust. [PDF]

open access: yesNat Geosci
Abstract Post-collisional magmatism has played a critical role in modifying the continental crust since the Archaean, 3 billion years ago. The dual mantle–crust signature of calc-alkaline post-collisional magmas requires a hybrid source involving both reservoirs, the formation of which is not well understood. Here we use an integrated

Interplay between oceanic subduction and continental collision in building continental crust

open access: yesNature Communications, 2022
AbstractGeneration of continental crust in collision zones reflect the interplay between oceanic subduction and continental collision. The Gangdese continental crust in southern Tibet developed during subduction of the Neo-Tethyan oceanic slab in the Mesozoic prior to reworking during the India-Asia collision in the Cenozoic.

Numerical models of slab migration in continental collision zones [PDF]

open access: yesSolid Earth, 2012
Continental collision is an intrinsic feature of plate tectonics. The closure of an oceanic basin leads to the onset of subduction of buoyant continental material, which slows down and eventually stops the subduction process.

Plume‐Induced Sinking of Intracontinental Lithospheric Mantle: An Overlooked Mechanism of Subduction Initiation?

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Although many different mechanisms for subduction initiation have been proposed, only few of them are viable in terms of consistency with observations and reproducibility in numerical experiments.

Body wave dispersion characteristics of regional deep earthquake at Southern Ryukyus subduction zone [PDF]

open access: yesE3S Web of Conferences, 2022
The convergent plate boundaries known as the subduction zone is the location where the cold, hydrate, and old oceanic plate subduct under the hot, dry, and young continental plate. The top of the oceanic plate, i.e. the oceanic crust usually is less than

The return of subducted continental crust in Samoan lavas [PDF]

open access: yesNature, 2007
Substantial quantities of terrigenous sediments are known to enter the mantle at subduction zones, but little is known about their fate in the mantle. Subducted sediment may be entrained in buoyantly upwelling plumes and returned to the Earth's surface at hotspots, but the proportion of recycled sediment in the mantle is small, and clear examples of ...
