In central Europe, evidence for Cadomian basement occurs from the Midlands Massif in the United Kingdom to the Moesian Platform in Romania. The patchily exposed basement rocks either have survived almost intact through the Phanerozoic (e.g. Lusatia), overstepped by different Palaeozoic strata, or have been reworked to various degrees (e.g. Erzgebirge) and involved in Variscan structures (e.g. Sudetes, Moravia). In the Polish and German lowlands, undated subsurface basement occurs below the Permo-Mesozoic cover and Variscan molasse and flysch successions. The mutual relationships between the various Cadomian fragments occurring within and/or below the Palaeozoic, both orogenic and platform successions, are far from fully understood.
