Exhumation processes in oceanic and continental subduction contexts: a review

S Guillot, K Hattori, P Agard, S Schwartz… - Subduction zone …, 2009 - Springer
Although the exhumation of high pressure (HP) and ultrahigh pressure (UHP) rocks is an
integral process in subduction, it is a transient process, likely taking place during the …

Collision vs. subduction-related magmatism: two contrasting ways of granite formation and implications for crustal growth

JF Moyen, O Laurent, C Chelle-Michou, S Couzinié… - Lithos, 2017 - Elsevier
Earth's continental crust is dominantly made of buoyant, felsic igneous material (granitoids),
that was ultimately extracted from the mantle as a result of Earth's differentiation. Since felsic …

Metamorphic conditions in orogenic belts: a record of secular change

M Brown - International Geology Review, 2007 - Taylor & Francis
In general, Archean rocks exhibit rather ordinary moderate-P-high-T facies series
metamorphism; neither blueschists nor any record of deep continental subduction and return …

High‐pressure granulites: formation, recovery of peak conditions and implications for tectonics

PJ O'Brien, J Rötzler - Journal of Metamorphic Geology, 2003 - Wiley Online Library
High‐pressure granulites are characterised by the key associations garnet‐clinopyroxene‐
plagioclase‐quartz (in basic rocks) and kyanite‐K‐feldspar (metapelites and felsic rocks) …

Global UHP metamorphism and continental subduction/collision: the Himalayan model

JG Liou, T Tsujimori, RY Zhang… - International Geology …, 2004 - Taylor & Francis
Continental crust (density~ 2.8 g· cm-3) resists subduction into the earth's mantle (~ 3.3 g·
cm-3) because of buoyancy. However, more than 20 recognized ultrahigh-pressure (UHP) …

Protracted, coeval crust and mantle melting during Variscan late-orogenic evolution: U–Pb dating in the eastern French Massif Central

O Laurent, S Couzinié, A Zeh, O Vanderhaeghe… - International Journal of …, 2017 - Springer
The late stages of the Variscan orogeny are characterized by middle to lower crustal melting
and intrusion of voluminous granitoids throughout the belt, which makes it akin to “hot” …

segments (French Massif Central (FMC), Vosges, Black Forest and Bohemian Massif (BM)) …

A general model for the intrusion and evolution of 'mantle'garnet peridotites in high‐pressure and ultra‐high‐pressure metamorphic terranes

Brueckner, Medaris - Journal of Metamorphic Geology, 2000 - Wiley Online Library
Garnet‐bearing peridotite lenses are minor but significant components of most metamorphic
terranes characterized by high‐temperature eclogite facies assemblages. Most peridotite …

The Variscan French Massif Central—a new addition to the ultra-high pressure metamorphic 'club': exhumation processes and geodynamic consequences

JM Lardeaux, P Ledru, I Daniel, S Duchene - Tectonophysics, 2001 - Elsevier
