   An attempt at holistic analysis of the Devonian rocks of Moravia is based on facies, tectonic information, palaeomagnetic data, and biodynamics of fauna in this easternmost part of the Variscan Orogen. Sediments and metasediments of the Moravian Karst, Nemcice-Konice, Horni Benesov, Rymarov-Vrbno and Tisnov facies were formerly parts of a large Rhenish-type basin developed on attenuated crust undergoing dextral transtension during the Emsian to Early Carboniferous. It communicated with other Rhenish-type basins along the southern Laurussian margin and, during Devonian times, may have been several hundred kilometres in length, oriented E-W. Most of the diastrophic sediments are Late Viseán. Basin eversion, reflected in cessation of diastrophic sedimentation, occurred during the Viseán/Namurian. Formerly remote facies-tracts were subsequently juxtaposed.
   Facies in various areas of western Moravia-Silesia suggest other basins, but additional data are needed to confirm or refute their former existence. The Givetian Mestecko Trnavka shale with its cover of diastrophic sediments may reflect Givetian-Frasnian collision occurring mainly in the Sudetic region in northern part of the Bohemian Massif The Velke Vrbno facies is suggested as representing a Barrandian-like sequence accreted to a volcanic arc during Devonian times. Major palinspastic breaks of tens to hundreds of kilometres are explained by strike-slip wedging and reworking of terranes controlled by clockwise rotation and bending of the orogen. Large crustal blocks were uplifted, dissected and ultimately completely erased from the structure
