Przedwaryscyjska ewolucja wybranych fragmentów peri-Gondwany: awalońsko-kadomskie podłoże waryscydów środkowoeuropejskich

Pre-Variscan evolution of selected fragments of peri-Gondwana: Avalonian-Cadomian basement of the Central European Variscides

 

In the Ediacaran (650-540 Ma),  the Avalonian-Cadomian orogeny took place along the Gondwana continental margin to which magmatic arcs were accreted and jointly formed what is known as peri-Gondwana.  In the Phanerozoic, fragments of peri-Gondwana became rifted and drifted away. The project aim is to  identify and reconstruct  the original position of  these fragments that eventually collided with Baltica.
