Interplay between oceanic subduction and continental collision …
网页2022年11月21日 — Generation of continental crust in collision zones reflect the interplay between oceanic subduction and continental collision. The Gangdese continental crust in southern Tibet developed...
Continental collision - Wikipedia
网页Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together. Continental collision is only known to occur on Earth.
Continental versus oceanic subduction zones - Oxford Academic
网页2016年8月11日 — Although normal oceanic crust is invariably subductable, descending of continental crust into the trench leads to subduction slowdown and eventually to failure. This tectonism is called continental collision or terrane accretion, by which two continental blocks contact with each other.
The transition from oceanic to continental subduction and collision…
网页2023年2月1日 — Warren et al. (2008) suggested that three mechanisms contribute to exhumation during the transition from oceanic subduction to continental collision: the geometry of the subduction zone, the strength of the crust at the continental margin, and the density of the subducting mantle lithosphere.
RESEARCH FOCUS: Understanding continental subduction: A …
网页2016年3月1日 — Between these lines of evidence, a compelling case can be built for the fact that continental lithosphere (crust and mantle) are subductable to great depths and significant distances away from the collision’s principal suture.
Continental Deep Subduction Versus Subduction Cessation: The …
网页2023年8月10日 — Integrated petrological-thermo-mechanical models reveal the favorable conditions of continental deep subduction or subduction cessation. Metamorphic densification of subducted continental lithosphere can provide great slab pull for continued continental deep subduction
The transition from oceanic to continental subduction and collision…
网页2023年2月1日 — Break-off of the oceanic slab can drive the exhumation of continental crust to shallower crustal levels along a subduction channel, which can expose HP–UHP metamorphic rocks, such as eclogites, in continental collision orogens (Liou et al., 2009, Zhang et al., 2016b, Zheng and Chen, 2016, Zhou et al., 2022).
A review on the numerical geodynamic modeling of continental subduction ...
网页2013年11月7日 — Continental subduction and collision normally follows oceanic subduction, with the remarkable event of formation and exhumation of high-to ultra-high-pressure (HP-UHP) metamorphic rocks. Based on the summary of numerical geodynamic models, six modes of continental convergence have been identified: pure shear thickening, folding and buckling ...
From subduction to collision: Control of deep processes on the ...
网页2003年4月19日 — We show that continental subduction and collision are two different processes. Thus their use as synonymous terms should be avoided. A continent can subduct when pulled by a subducted portion of oceanic plate, with negligible surface shortening outside the trench.
Editorial: Subduction and collision dynamics of tectonic plates
网页2022年9月8日 — Continental collision generally occurs following the closure of oceanic subduction and leads to the formation of mountain belts. The collision pattern varies among different mountain ranges; even the same collision zone shows significant lateral tectonic variations along its strike.
