“…Sedimentary basins, constituting the lower Palaeozoic cover series in the Eastern Alps, contain acidic volcanics among lower Palaeozoic sediments (Loeschke and Heinisch 1993) with a well-documented sedimentary evolution (Schönlaub 1997a(Schönlaub , 1997bSchönlaub and Heinisch 1993;Schönlaub and Histon 2000), representing a rifting environment since the Late Ordovician (Neubauer and von Raumer 1993;Neubauer and Sassi 1993;Sassi et al 1994). Since the Late Ordovician, many areas are covered by the detrital sediments of Ordovician glaciation (e.g.…”

“…The sedimentary basins constituting the Lower Palaeozoic cover series in the Eastern Alps represented the northern margin of Palaeotethys. They contain acidic volcanics among Lower Palaeozoic sediments (Loeschke and Heinisch, 1993) with a welldocumented sedimentary evolution (Schönlaub and Heinisch, 1993;Schönlaub and Histon, 2000), representing a rifting environment since the Late Ordovician (Neubauer and von Raumer, 1993;Neubauer and Sassi, 1993). In contrast, the southern passive margin of Palaeotethys is located in the Iranian occurrences, and a similar evolution is found in the Cimmerian part of Turkey (references in Stampfli and Kozur, 2006), and North Africa.…”

“…This assumption is hypothetical, but the basalts could represent early precursors of the alkaline withinplate basalts occurring directly beneath the Streifwald flysch turbidites. Numerous alkaline within-plate basalts of Silurian/Devonian age are found in other places of the Eastern Alps (Loeschke 1989) and generally indicate crustal stretching and intensified rifting of continental crust during the Silurian and Devonian (Loeschke and Heinisch 1993).…”

The South-Alpine Carnic Alps are part of the southern flank of the European Variscides and display a continuous sedimentary record from Late Ordovician to Devonian times followed by Carboniferous S-directed nappe stacking and Late Carboniferous to Early Permian post-collisional collapse. The tectonometamorphic and sedimentary evolution of the Carnic Alps resembles a continuous process where pre-and syn-orogenic volcanism, syn-orogenic flysch sedimentation, deformation including nappe stacking, metamorphism and tectonic collapse shift in age from internal zones in the N towards external zones in the S. New structural, petrological and sedimentological data are presented concerning the tectonometamorphic history of the Carnic Alps. We distinguish three thrust sheets or tectonic nappes differing in their stratigraphic, sedimentological, deformational and metamorphic histories which were thrust over each other in Carboniferous times. Our data lead to a new geodynamic model showing an evolution from rifting or backarc spreading in the Late Ordovician to the establishment of a mature passive continental margin in the Late Devonian/Early Carboniferous, flysch sedimentation in an active continental margin setting during the Visean/Namurian and finally collision during the Late Carboniferous between the northern margin of Gondwana and a microcontinent to the N.
