This region has remained emergent for protracted periods spanning from the Variscan Orogeny
to the Cenomanian and from the Turonian to the Holocene.
D1 and D2 correspond to the collisional stage of the Variscan orogeny
and are thought to be of Mid-Upper Devonian to Early-Mid-Carboniferous age.
A major worldwide geodynamic event, the Variscan orogeny
sensu lato, culminated during the Permian.
The oldest structural stage is associated with the Variscan orogeny
, after which a Late Palaeozoic graben was formed in the Fore-Sudetic Block.
Carboniferous magmatism in the Sudetes is synchronous with the development and consolidation of the Variscan orogeny
The Bohemian Massif was not markedly deformed after the Variscan orogeny
and become a firm consolidated basement.
Furthermore, he believed that the Silurian in the Lugicum is folded by Caledonian orogeny, while Devonian Rheinisch development is significant in the Silesicum, which was folded and metamorphosed by the Variscan orogeny

The Moldanubian Proterozoic was completely folded and faulted during the Variscan orogeny
, whereas in the Brunovistulian Proterozoic such Variscan overprint could not be observed.
The Prague Basin, Tepla-Barrandian Unit, Czech Republic, is a large Ordovician to Devonian basin which was tilted during Variscan Orogeny
. Similarly to the other peri-Gondwanan terrains, it preserves evidence of intense basic volcanic activity during the Silurian (Stampfli et al.
Older granitic rocks are usually influenced by Variscan orogeny
