Are the oroclines of the Variscan belt related to late Variscan strike‐slip tectonics?

Terra Nova, 2011
Terra Nova, 23, 241–247, 2011AbstractEarly Variscan structures and magnetic anomalies delineate four oroclines along the Variscan belt. The arcs bend the lithostratigraphic zones of the autochthon and the allochthonous terranes, which include ophiolites of the Rheic suture and units of Gondwanan derivation subducted on both sides of the Rheic Ocean.

The South-Western Branch of the Variscan Belt: Evidence from Morocco

Tectonophysics, 2010
Abstract This work is based on the compilation and re-evaluation of the most significant data, either personal or from the literature, concerning the Moroccan Variscides. The latter constitute the only, moderately disturbed or even undisturbed part of the South-Western Branch of the Variscan Belt, facing directly NW Gondwana.

Postcollisional granites in the South Tien Shan Variscan Collisional Belt, Kyrgyzstan

Journal of Asian Earth Sciences, 2002
Abstract Two major types of the potassium-rich postcollisional granites of Permian age were studied in the South Tien Shan Variscan Collisional Belt. The first type, metaluminous granites of the Jangart complex, are located along the southeastern boundary of this belt with the Precambrian Tarim Block.

Oroclinal arcs of the Variscan Belt: features and mechanisms

2023
Arcuate trace of large structures characterizes many mountain chains. The Variscan Belt is not an exception, and depicts one of the tightest oroclines in the world, the Ibero-Armorican Arc. In addition, the belt features a few more open arcs in the Eastern Moroccan Meseta, Central Iberia, the French Massif Central and the Bohemian Massif.

The collapse of the Variscan belt: a Variscan lateral extrusion thin-skinned structure in NW Iberia

International Geology Review, 2020
The Iberian Massif of the Variscan Belt is a big area of exposed Palaeozoic rocks holding an S-shaped regional bend.

Kinematics of the Forcarei Synform (NW Iberian Variscan belt)

Geological Society, London, Special Publications, 2011
Abstract The Forcarei Synform is a kilometric fold developed in the hinterland of the NW Iberian Variscan belt. A detailed analysis of the synform, based on quartz fabrics and kinematic markers, shows pervasively deformed rocks that have been continuously deformed during the last two main Variscan deformation phases (D

Eastern Variscan fold belt: Paleomagnetic evidence for oroclinal bending

Geology, 1996
The Rhenohercynian zone of Variscan Europe trends from southern Portugal, around the Ibero-Armorican arc, into southern Britain, Belgium, northern Germany, and the Moravo-Silesian zone of the east Czech Republic. Although the geodynamic evolution of the central and western segments of this arcuate belt is now fairly well understood, the scenario for ...
