Lithospheric structure and tectonic memory of the European Variscan belt

Geological Society, London, Special Publications
The Variscan belt of Europe formed during the late Paleozoic through the convergence of Laurussia and Gondwana, subduction of intervening oceans, and the accretion of peri-Gondwanan terranes during Pangaea assembly. This study integrates geological, geophysical and crust–mantle structural data to investigate the orogen's construction, destruction and ...

“Pelagic” Carbonates in the Variscan Belt — Their Sedimentary and Tectonic Environments

, 1983
The setting of condensed pelagic limestones in the Variscan Belt is reviewed and discussed with special respect to the depth of deposition. Since microfacies studies fail to provide unequivocal evidence, the interpretation has to rely mainly on the faunas and on the character of the adjacent facies units.

Pre-Alpine contrasting tectono-metamorphic evolution within the Southern Steep Belt (Central Alps)

, 2015
In the Southern Steep Belt, Italian Central Alps, relicts of the pre-Alpine continental crust are preserved. Between Valtellina and Val Camonica a polymetamorphic rock association occurs, belonging to the Upper Austroalpine units, which includes ...

Late Variscan, Permo-Carboniferous, Al-K plutonism in the South Portuguese Zone: El Crispinejo cordierite-bearing granite.

Geologica Acta, 2017
The El Crispinejo granite forms part of a small, but distinctive late intrusive suite of cordierite-bearing peraluminous granites in the South Portuguese Zone (SPZ). This granite has the best outcrop relationships of the suite.

Chemical and mineralogical data of the metalliferous mineralization from S. Carlo mine (Peloritani mts, Ne Sicily, Italy)

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2006
The mineralization processes in the Peloritani Belt (Southern Sector of the Calabria- Peloritani Arc) prevalently developed during the Variscan orogenesis producing Pb, Zn, Fe, As, Sb, Cu, Ag, W, etc. polymetalliferous ore-bearing horizons.

The Long-Lasting Exhumation History of the Ötztal-Stubai Complex (Eastern European Alps): New Constraints from Zircon (U–Th)/He Age-Elevation Profiles and Thermokinematic Modeling [PDF]

Lithosphere
The Eastern European Alps formed during two orogenic cycles, which took place in the Cretaceous and Cenozoic, respectively. In the Ötztal-Stubai Complex—a thrust sheet of Variscan basement and Permo-Mesozoic cover rocks—the record of the first (Eoalpine)

Petrogenetic link between metasedimentary rocks, migmatites and granitoids in the Variscan basement of the Pontgibaud area, French Massif Central – implications for the crustal structure

BSGF - Earth Sciences Bulletin
The architecture of the crust in the French Massif Central (FMC) is described as a nappe stack composed, from top to bottom, of the Upper Gneiss Unit (UGU), the Lower Gneiss Unit (LGU), and the Para-Autochthonous Unit (PAU), which are intruded by ...

An Upper Devonian foredeep basin in the Southern Central Iberian Zone (Variscan Iberian Massif): Consequences for Variscan plate dynamics

New field research and revision of previous works in the Variscan Iberian Massif unravel the existence of an Upper Devonian foredeep basin in the southern Central Iberian Zone, close to the suture area with the Ossa-Morena Zone.

At the border of peri-Gondwana and Baltica: the structure of the eastern termination of the Variscan belt

International audienceThe termination of the eastern Variscan belt has long been a matter of debate because it is deeply concealed beneath younger sediments.
