The Addition of Felsic Sediments to the Lower Continental Crust During the Variscan Orogeny

Geochemistry, Geophysics, Geosystems
Lower crustal metasedimentary xenoliths (garnet‐sillimanite granulites) from the Bournac breccia pipe in the Massif Central, France, provide a robust example of sediments transported to depth and incorporated into stable lower continental crust during a ...

High-K, I-type Tonian post-collisional magmatism in the South Delhi Terrane, NW India: Petrogenetic and tectonic implications

Geosystems and Geoenvironment
The limited whole-rock geochemical data of the granitoids exposed in the southern domain of the South Delhi Terrane, Aravalli orogen, northwestern India characterised these rocks as subduction-related continental arc I-type granites.

Unveiling Cenozoic Volcanism in the Takab‐Shahindezh Area Induced by Slab‐Mantle Interaction in the Zagros Orogen, NW Iran

Geochemistry, Geophysics, Geosystems
The Zagros orogen records the closure of the Neotethys Ocean by northward subduction of the oceanic slab beneath the Iranian plate. Northwestern Iran has undergone episodic volcanism since the Eocene, due to a shift of tectonic regimes from subduction to

Exhumed Serpentinites and Their Tectonic Significance in Non‐Collisional Orogens

Geochemistry, Geophysics, Geosystems
Exhumed serpentinites are fragments of ancient oceanic lithosphere or mantle wedge that record deep fluid‐rock interactions and metasomatic processes. While common in suture zones after closure of ocean basins, in non‐collisional orogens their origin and

Age, petrogenesis and metamorphism of the syn-collisional Proven Igneous Complex, West Greenland

, 2005
The Paleoproterozoic Prøven Igneous Complex (PIC) in West Greenland extends from ca. 72°15′ to 73°10′N, approximately 500 km north of the subduction-related intrusive complex in the core of the +1100 km wide, asymmetric collisional Nagssugtoqidian ...

The thermal structure of collisional orogens – insights from the Grenville orogen in Canada and Scotland

Exhumed collisional orogens provide important time-integrated records of metamorphic, magmatic and deformation processes occurring over timescales of up to hundreds of millions of years. When combined with observations and principles from present-day deformed continental regions, research of deeply-exhumed terrains enables the conditions and timescales
