The Dabie‐Sulu belt of east‐central China, the Kokchetav Complex of northern Kazakhstan, the Maksyutov Complex of the South Urals, the Dora Maira Massif of the Western Alps, and the Western Gneiss Region of southwestern Norway lie astride intracontinental suture zones. All represent collisional mountain belts. Adjoining Eurasian regions exhibit little or no evidence of a coeval calc‐alkaline arc. Each metamorphic complex contains mineralogic and textural relics of the presence or former… 
Deformation history of the eclogite‐ and jadeitite‐bearing mélange from North Motagua Fault Zone, Guatemala: insights in the processes of a fossil subduction channel
In Guatemala, along the northern side of the Motagua Valley, a mélange consisting of blocks of eclogite and jadeitite set in a metaserpentinitic and metasedimentary matrix crops out. The
The diamond‐bearing Kokchetav UHP massif in Northern Kazakhstan: exhumation structure
In the Kokchetav ultrahigh‐pressure (UHP) massif in northern Kazakhstan, diamond‐bearing UHP rocks occur exclusively in a western, rhomb‐shaped domain, that differs from an eastern transpressional
Eclogites of the Bergen Arcs Complex, Norway: Petrology and Mineral Chronometry
A considerable portion of the Bergen Arcs polymetamorphic complex (southwestern Norway) is composed of anorthosite rocks strongly reworked in the course of two regional metamorphic events, granulite
Pre‐collisional high pressure metamorphism and nappe tectonics at active continental margins: a numerical simulation
The evolution of a subduction channel and orogenic wedge is simulated in 2D for an active continental margin, with P‐T paths being displayed for selected markers. In our simulation, subduction
White mica trace element and boron isotope evidence for distinctive infiltration events during exhumation of deeply subducted continental crust
ABSTRACT Previous study of subducted continental crust within the Luliang Shan terrane in Northwest China has documented metasomatic formation of thick, hydrated phengite + garnet-rich selvages at
Consequences of progressive eclogitization on crustal exhumation, a mechanical study
SUMMARY The very low water content of the granulitic unit of Holsnoy, in the Bergen Arcs, Norway, caused its partial metastable preservation throughout Caledonian burial end exhumation, leading to
The Exhumation of Eclogite-Facies Metamorphic Rocks—a Review of Models Confronted with Examples from the Alps
We summarize recently proposed models for the exhumation of (ultra-) high pressure ([U]HP) metamorphic units within collisional orogens. In terms of mechanics, exhumation is either caused by buoyancy

We summarize recently proposed models for the exhumation of (ultra-) high pressure ([U]HP) metamorphic units within collisional orogens. In terms of mechanics, exhumation is either caused by buoyancy
Discovery of coesite from Indus Suture Zone (ISZ), Ladakh, India: Evidence for deep subduction
Coesite, the high-pressure polymorph of quartz has been identified for the first time in the Tso-Morari Crystalline Complex, Ladakh (India) in the Himalayan belt. The preservation of coesite grains
Exhumation of high‐pressure metamorphic rocks in a subduction channel: A numerical simulation
High‐pressure metamorphic rocks provide evidence that in subduction zones material can return from depths of more than 100 km to the surface. The pressure‐temperature paths recorded by these rocks
