Tectonometamorphic evolution of the Aracena metamorphic belt (SW Spain) resulting from ridge-trench interaction during Variscan plate convergence

, 2006
[1] The Aracena metamorphic belt is a high-temperature/low-pressure (HT/LP) band located at the southern end of the European Variscan chain. It marks a suture between Armorica and Avalonia.

Spinels of Variscan olivine hornblendites related to the Montnegre granitoids revisited (NE Spain): petrogenetic evidence of mafic magma mixing

Geologica Acta, 2017
Olivine hornblendites (cortlandtites) form part of the Montnegre mafic complex related to late-Variscan I-type granitoids in the Catalan Coastal Ranges.

Late Variscan tectonic orogenic collapse as a trigger for Sn-W mineralizing systems. U-Pb ore geochronology across the Martinamor gneissic dome (Salamanca, Spain)

Regional tectonothermal evolution is a primary factor for many mineral deposits formation. Late orogenic gravitational collapse has been widely recognized across different orogens, including the Variscan belt.

Oroclines of the Iberian Variscan belt: Tectonic and paleogeographic implications

, 2015
The Western European Variscan orogenic belt is thought to represent the final in a series of Paleozoic continental collisions that culminated with the amalgamation of the supercontinent Pangea. The Iberian segment of the Variscan belt is characterized by

Geochemistry of Variscan lamprophyre magmatism in the Saxo-Thuringian Zone

, 2013
Lamprophyres are mantle-derived magmatic rocks, commonly occurring as dikes. They are readily identified from their field setting, petrography, chemical and mineralogical composition.

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 ...

Outline of the Variscan basement of Sardinia [PDF]

, 2009
In Sardinia a quasi-complete section of the southern branch of the Variscan orogenic belt crops out, characterized by non-metamorphosed to high-grade rocks, whose age ranges from Early Cambrian to Early Carboniferous, and that are involved in a complex ...

Extensional perpendicular orthogonal quartz veins related to early Variscan Orogeny

Orthogonal sets of veins perpendicular to the bedding occur in fold-and-thrust belts; however, the timing of their formation remains unclear in relation to orogeny. This study aims to explain the development of perpendicular orthogonal vein sets from the
