Continental Deep Subduction Versus Subduction Cessation: The Fate of Collisional Orogens

Tectonics, 2023
AbstractThe contrasting fates of collisional orogens, that is, continental deep subduction or subduction cessation, are widely recognized by petrological, paleomagnetic and geophysical observations. However, the mechanisms of such different collisional modes, especially the dynamics of continental deep subduction, are controversial.

Seismic probing of continental subduction zones

Journal of Asian Earth Sciences, 2017
Abstract High-resolution images of Earth’s interior provide pivotal information for the understanding of a range of geodynamic processes, including continental subduction and exhumation of ultrahigh-pressure (UHP) metamorphic rocks. Here we present a synthesis of available global seismic observations on continental subduction zones, and selected ...

Metamorphic zirconology of continental subduction zones

Journal of Asian Earth Sciences, 2017
Abstract Zircon is widely used to date geological events and trace geochemical sources in high-pressure (HP) to ultrahigh-pressure (UHP) metamorphic rocks of continental subduction zones. However, protolith zircons may be modified by three different types of metamorphic recrystallization via mechanisms of solid-state transformation, metasomatic ...

Intralithospheric mantle structures recorded continental subduction

Journal of Geophysical Research: Solid Earth, 2012
We investigated the intralithospheric mantle (ILM) structures beneath the North China Craton (NCC) by the seismic imaging with over 16,000 high‐quality receiver functions from 255 broadband stations. These images were created for six profiles spanning different tectonic units in the NCC.

Subductability of continental lithosphere

Geological Society of America Bulletin
Abstract Multiple lines of evidence from geological and geophysical observations indicate the deep subduction of continental lithosphere; however, the potential and driving forces of (self-sustained) continental subduction remain unclear.

Fragmentation of continental subduction is ending the Himalayan orogeny

Science Bulletin, 2023
After two continents collide, plate convergence and orogenesis are sustained because subducted continental lithosphere continues pulling the surface plate. It remains controversial how, why, and when continental plate convergence and collision slow down and eventually cease.
