The Variscan orogeny in Chios (Greece): Carboniferous accretion along a Palaeotethyan active margin
Terra Nova, 2003ABSTRACT New stratigraphic and structural data on the turbiditic succession of Chios (Volissos turbidites) suggest that this clastic wedge formed during the Early Carboniferous. These turbidites, fed long‐distance by erosion of the Variscan orogen, were most likely deposited in a Palaeotethyan remnant‐ocean basin.

Appalachians in the Time Interval between the Grenville Orogeny and Variscan Collision
1999Both in the southern and northern Appalachians, inliers of Grenville rocks are surrounded and overthrust by Phanerozoic and Neoproterozoic rocks.

Mobilization of tin during metamorphism in the Variscan Orogeny
The Erzgebirge, a major tin (Sn) province in the Variscan orogenic belt, hosts substantial Sn deposits associated with post-kinematic granites, alongside the minor stratabound Sn deposits found in the metamorphic schists of the western Erzgebirge. These schists are derived from Early Ordovician siliciclastic sediments, which were metamorphosed during ...Owishi Sarkar +3 more

The significance of the Variscan orogeny in the Świętokrzyskie Mountains (Mid Polish Uplands)
Geologische Rundschau, 1992The Świetokrzyski Horst, created during the Laramide phase, is situated in the central part of the Mid Polish Uplands. It is composed of folded Paleozoic rocks partly covered by Mesozoic sediments. In this area two tectonostratigraphic units can be distinguished: the Kielce Unit to the S and the Łysogory Unit to the N.

The Cadomian orogeny and its influence on the Variscan evolution of western Europe
Geological Society, London, Special Publications, 1990Abstract The south-north zonation of the Variscan orogen in Western Europe, from Ligerian internal mobile zones in the south, to Hercynian external ensialic zones in the north, appears to be controlled by the north-south zonation in the older Cadomian orogenic belt which was developed in the northern margin of Gondwana.

A review of the Irish crustal structure and signatures from the Caledonian and Variscan Orogenies
Terra Nova, 2005AbstractThis paper reviews the complex crustal and upper‐mantle seismic velocity structure of Ireland and surrounding seas. Data from 11 seismic refraction profiles reveal that onshore Ireland mean crustal velocities range between 6.25 and 6.5 km s−1 with crustal thickness of 28.5–32 km.

The Cadomian Orogeny in the supercontinent cycle and its importance for Variscan orogenic processes
During Ediacaran to earliest Cambrian times, the Cadomian Orogen was formed on the periphery of the Gondwana supercontinent. The orogenic belt was structured in the geotectonic style of the recent western Pacific region. Cadomian arcs and marginal basins aged at c.Linnemann, Ulf +3 more

About this title ‐ The Variscan Orogeny: Extent, Timescale and the Formation of the European Crust
Geological Society, London, Special Publications, 2014This volume summarizes the state of the art of Variscan geology from Iberia to the Bohemian Massif. 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 ...

International Journal of Coal Geology, 1989
Abstract The coal basins at the Variscan front in Western Europe provided the first examples of prefolding coalification that was linked to an early high geothermal history. The coalification occurred almost contemporaneous with sedimentation and prior to folding.
