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.

Late Variscan Nonmarine Basin Deposits, Northwest Africa: Record of Hercynotype Orogeny
1976The principal Paleozoic deformation, metamorphism, and plutonism in northwest Africa occurred during late Carboniferous phases of the Variscan Orogeny. Fifteen remnants of nonmarine deposits scattered across the Moroccan and Oranian mesetas record predominantly vertical displacement during late Variscan phases. Nine deposits are thick (as much as 2000m)

The Cadomian accretionary orogeny at the end of Neproterozoic to early Cambrian was one of the principal crustal growth events in Europe, as indicated by a number and widespread distribution of Cadomian basement units within the Variscan and Alpine orogenic belts.

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 ...

Rare-element pegmatite-forming melt during Variscan orogeny: genesis, propagation and consolidation
2015The Variscan rare-element pegmatite fields mainly enriched in Li, Nb and Ta are subject to increasing mining exploration in the last few years. Indeed, Li from pegmatite deposits is recognised to be less sensitive to supply disruptions than Li from brine deposits.
