Abstract

ORIG CZ

V originále

The early Variscan phase of the evolution of Brunovistulian terrane was characterized by the formation of Devonian extensional basins and WPA volcanic activity. The compressive phase is recorded in synorogenic flysch sedimentation, which shows a distinct polarity. The oldest flysch (Protivanov and Andelska Hora Fm.) contains clastic micas from early Paleozoic crystalline rocks that are assumed to be derived either from an active Brunovistulian margin, now covered by the Lugodanubian nappes, or from the terranes of Armorican affinity. At the beginning of the Namurian the development of the Moravo-Silesian late Paleozoic basin was terminated by coal-bearing paralic and limnic sediments. The progressive Carboniferous stacking of nappes and their impingement on the Laurussian foreland led to crustal thickening and shortening. The Devonian preorogenic and Carboniferous synorogenic sedimentation bears close similarity to the Rhenohercynian Zone of Germany. Although both regions had a different Late Proterozoic to Early Palaeozoic history (Kalvoda et al. 2003), this parallelism reflects similar geotectonic regimes at the southern margin of Laurussia (Bábek et al. 2006). In both areas crustal extension and differential subsidence accompanied by felsic and basic within-plate volcanism (Floyd 1995) contributed to the development of structural lows and rises in a system of halfgrabens (Lütke 1990, Kalvoda 1998, Kalvoda and Melichar 1999) and brought about a pelagic regime (“Herzynische Fazies”). Nevertheless, there are also some differencies. While the northern highs of the Caledonian Old-Red continent furnished most of the Rhenohercynian basin with siliciclastic input throughout the Devonian, in the Moravosilesian basin the siliclastic input was restricted and connected rather with the initiation of rifting (Kalvoda 1995). It is possible to correlate the structurally highest flysch tectonic units of the Brunovistulian terrane with the Giessen- Harz Nappe based on the following evidence. Tectonic slices of Devonian hemipelagic sediments and volcanites of the Drahany facies domain and the Silurian exotics at the base of the Protivanov unit (Kettner and Remes 1936, Chadima and Melichar 1998, Bábek et al. 2005) are comparable with the “Stiege-Olistostrom” at the base of the Giessen-Harz nappe. The presence of the enigmatic Bohemian Silurian facies and fauna at the base of the Protivanov Fm. is similar to the blocks with Armorican affinities at the base of the Giessen-Harz nappe (Huckriede et al. 2004, Franke 1995). Nevertheless, it should be stressed that the evidence for Armorican affinities in all these blocks is rather weak and similar facies may have developed on the southern margin of Avalonia. As the flysch material of the Giessen-Harz nappe was derived from the Armorican Mid German Crystalline Rise, the correlation with the Protivanov nappe may also be reinforced by the presence of Ordovician and Silurian white micas in the latter (Schneider 2002).
