Indenters and Ribbons: Cratonic Lithosphere in the Variscan Belt

The Variscan orogen of Europe and northwestern Africa represents one of the most complex collisional systems on Earth, assembled during the diachronous convergence of Laurussia and Gondwana in the late Palaeozoic. Unlike classic continent–continent collisions dominated by the interaction of two large cratonic masses, the Variscan belt developed through

Geothermal Control of Granite Compositions in the Variscan Orogenic Belt

Nature Physical Science, 1973
I HAVE shown that the average compositions of granites in the Variscan, Caledonian and Alpine orogenic belts differ, and have attributed their differences to formation by partial melting under different geothermal gradients1. A geochemical examination of the granites in the Caledonian orogenic belt suggested that regional variation within the orogenic ...

Variscan metamorphism and K-Ar dates in the Variscan fold belt of S Brittany and NW Spain

Journal of the Geological Society, 1979
The metamorphism in Lower Palaeozoic rocks in the Variscan fold belt of S Brittany and NW Spain is not evenly distributed but forms HT, LP thermal domes with migmatites and granites, separated by rocks with lower grades of metamorphism. 41 mica dates, ranging from 332 to 262 Ma, obtained from granites, decrease in age westwards along the fold belt ...

The Iapetus model: a plate tectonic concept for the Variscan belt of Europe

Tectonophysics, 1989
Abstract A plate tectonic model is presented explaining the evolution of the Variscan belt of Europe. It regards the Iapetus Ocean and its branch, the Tornquist Sea, as the only ocean involved in the Caledonian, Variscan and Alleghenian mega-orogen.

Discrete pulses of Variscan magmatic activity in the Erzgebirge (Eastern Variscan belt) and their relation to ore formation

Recently, new age data have been published for the Variscan magmatism as well as for times of ore formation in the Erzgebirge (e.g., Breitkreuz et al., 2021; Burisch et al., 2019; Meyer et al., 2024; Leopardi et al., 2023; Löcse et al., 2020; Reinhardt et al., 2022; Tichomirowa et al. 2019, 2022).
