This approach is applied to study different levels of the orogenic crust in two Variscan massifs − the OrlicaŚnieżnik Dome (Sudetes) and the Vosges Mountains (NE France) − in order to decipher their Palaeozoic evolution .g., Matte.
The Variscan orogeny involved a complicated heterogeneous assembly of different microplates and heterochronous collisions, making the exact reconstruction of the plate tectonic processes difficult. Plate convergence that caused the Caledonian orogeny in the Silurian continued to form the Variscan orogeny in the succeeding Devonian and Carboniferous Periods Noté /5: Achetez Variscan Orogeny de Russell Jesse: ISBN: 9785514023318 sur amazon.fr, des millions de livres livrés chez vous en 1 jou The Variscan (often termed Hercynian) orogeny spans most of central and south-eastern Europe from South Portugal to Poland and beyond into the Balkans and Turkey. It is a collage of microcontinents which drifted off from the northern margin of Gondwana and includes Avalonia and the Armorican Terranes Assemblage (ATA). Break-up started by southward subduction under Gondwana during the Late. In Western Corsica, remnants of pre-batholitic lithological and metamorphic assemblages are preserved as km-scale septa enclosed within Lower Carboniferous to Early Permian plutons. Two groups of septa were recognized: (1) the Argentella and Agriates-Tenda fragments correspond to Neoproterozoic rocks deformed and metamorphosed during the Cadomian-Panafrican orogeny, and (2) the Zicavo, Porto.
The European Variscan belt consists of two orogens: the older, northern and the younger, southern. The northern Variscan realm was dominated by Late Devonian-Carboniferous rifting, subduction and collisional events as defined by sedimentary records, crustal growth, recycling of continental crust and large-scale deformations. In contrast, the southern European crust was reworked by major Late Carboniferous collision followed by Permian wrenching. The Late Carboniferous-Permian orogeny.
The Variscan orogeny (Hercynian orogeny) is an ancient mountain-building event in the late Palaeozoic era. It was caused by a continental collision between Euramerica (Laurussia) and Gondwana to form the supercontinent of Pangaea. It explains many older features of the present-day world The Ibero-Armorican Arc is nestled within the Western European Variscan Belt, a complex continental-scale orogen (1000 km wide and 8000 km long) that formed through a series of protracted tectonic..

The basin was inverted and multiply deformed during the Late Devonian to early Carboniferous Variscan orogeny, and its structural inventory provides an intriguing record of complex geodynamic processes that led to growth and collapse of a Tibetan-type orogenic plateau stages of the Variscan orogeny at the southern part of the Iberian Massif. The study of the faults and dikes developed during this period in the southern Iberian Massif allowed us to establish the characteristics of the evolving kinematics in this area. These results have been used to develop a model for this period based on the concept of escape tectonics. Of TECTONICS, VOL. 23, TC6001, doi.

The Variscan or Hercynian orogeny is a geologic mountain-building event caused by Late Paleozoic continental collision between Euramerica (Laurussia) and Gondwana to form the supercontinent of Pangaea. Precambrian rocks from the Iberian Peninsula suggest it too probably formed part of core Gondwana before its detachment as an orocline in the Variscan orogeny close to the Carboniferous. The Alpine orogeny was the last of the three major phases of orogeny in Europe that made its geology. The Caledonian orogeny which formed the Old Red Sandstone continent was the first. The second was the Variscan orogeny. That was when Pangaea formed as Gondwana and the Old Red Sandstone continent collided in the middle to late Palaeozoic Variscan orogeny, Hercynian orogeny, Variscan diastrophism; Armorican orogeny [obsolete] herzynische Gebirgsbildung f, variscische Gebirgsbildung, herzynisches Orogen n, variscisches Orogen, Varisikum Jun 17, 2016 - Distribution of orogenies with similar ages to the Variscan orogeny (shaded
The morning of the third day is devoted to the granite magmatism so characteristic of the Variscan orogeny, and its relationship with ore genesis, an important topic if one keeps in mind that the Industrial revolution in the XIX th century was made possible thanks to the Variscan ores and carbon and that European economy could still draw some benefits from these resources The oldest structural stage is associated with the Variscan orogeny, after which a Late Palaeozoic graben was formed in the Fore-Sudetic Block. Geodynamics of south-eastern part of the Central European subsidence zone Carboniferous magmatism in the Sudetes is synchronous with the development and consolidation of the Variscan orogeny structure
The Variscan orogeny is the name given to the whole set of geological processes which deeply modified the continental crust of western Europe and the north and northwest of Africa during the Late Paleozoic (Devonian-Permian). In its long period of activity (approximately 80 million years), this orogeny shortened and intensely deformed those sediments deposited previously along vast continental.

Pangaea. Supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 335 million years. The Variscan orogeny is the major Middle to Late Palaeozoic tectonometamorphic event in central Europe. It represents the final collision of Gondwana with the northern continent, Laurasia, and marks the European version of the evolution of the supercontinent of Pangaea at the end of the Palaeozoic (McCann 2008a). During the Cretaceous to Tertiary, the post-Variscan stage was followed by. Les Vosges sont caractérisées par la présence de nombreuses intrusions et extrusions magmatiques d'affinités variées.

The Anti-Atlas belt is well known for its numerous copper deposits. It displays also a complex geological, metallogenic and tectonic history which is challenging for mining companies in order to better understand and prospect these Cu-deposits.
