TLDR
In this article, a physical model of continental subduction is presented, which reveals two principal regimes: a highly compressional (HC) regime and a low compressional regime characterised by high and low pressure between the overriding and subducting plates, respectively.About:

Ultrahigh-pressure metamorphism: tracing continental crust into the mantle
TL;DR: More and more evidence is being discovered in Phanerozoic collision belts of the burial of crustal rocks to previously unsuspected (and ever increasing) depths, presently on the order of 150-200 km, and of exhumation from such depths as mentioned in this paper.

Sm–Nd and Rb–Sr isotopic chronology and cooling history of ultrahigh pressure metamorphic rocks and their country rocks at Shuanghe in the Dabie Mountains, Central China
TL;DR: In this article, the authors showed that the retrograde metamorphism of UHPM rocks occurred in an open chemical system, whereas the Nd and Sr isotopic systematics of UHP minerals may have remained closed.
Journal ArticleDOI
Subduction tectonics and exhumation of high pressure metamorphic rocks in the Mediterranean orogens
TL;DR: In this article, the authors discuss the mechanisms of syn-orogenic exhumation of high pressure (HP) and ultra-high pressure (UHP) rocks in the peri-Mediterranean blueschist belts.
Journal ArticleDOI
Evolutionary model of the Himalaya–Tibet system: geopoem: based on new modelling, geological and geophysical data
TL;DR: In this paper, a two-dimensional thermo-mechanical laboratory modelling of continental subduction was performed, which confirmed that the continental crust can be deeply subducted and showed that slab break-off, delamination and tectonic underplating are fundamental events with drastic consequences on the subsequent evolution of the convergent system.

Lithospheric strength and its relationship to the elastic and seismogenic layer thickness
Anthony Watts,Evgenii Burov +1 more
TL;DR: In the oceans, the effective elastic thickness of the lithosphere, Te, is the range 2-50 km and is determined mainly by plate and load age, whereas the continents, in contrast, are characterised by Te values of up to 80 km and greater as mentioned in this paper.

Lithospheric buoyancy and collisional orogenesis: Subduction of oceanic plateaus, continental margins, island arcs, spreading ridges, and seamounts
TL;DR: The sizes of continental blocks, basaltic oceanic plateaus, and island arcs that would cause collisional orogenesis when they enter a subduction zone are calculated in an analysis based upon the assumption of local isostasy and the assumption that plate subduction is primarily driven by the negative buoyancy of the lithosphere.

Structures of Ophiolites and Dynamics of Oceanic Lithosphere
TL;DR: In this article, the authors present an analysis of ophiolite structures in the context of oceanic lithosphere and asthenosphere and discuss the importance of the Ophiolites as markers of past plate tectonics.

A mechanism for syn-collisional rock exhumation and associated normal faulting: Results from physical modelling
TL;DR: In this article, a three-layer model of the continental lithosphere is used to model the subduction process of the Himalayas, and the results of the modelling are tested on the example of the Mt. Kilimanjarvis.

Tectonic setting for ophiolite obduction in Oman.
TL;DR: The Samail ophiolite is part of an elongate belt in the Middle East that forms an integral part of the Alpine mountain chains that make up the northern boundary of the Arabian-African plate as mentioned in this paper.

Shear zones, thrusts and related magmatism in the Oman ophiolite: Initiation of thrusting on an oceanic ridge
TL;DR: In this article, high-temperature N-S to NW-SE trending shear zones have been discovered in the peridotites and gabbros of the Oman ophiolite.
