Abstract

The authors present a stratigraphic and facial correlation of the Variscan sequences of the Szendro-Uppony Paleozoic of the Gemer-Bukk units (NE Hungary) with those of the South Alpine Carnic Alps-South Karawanken Mts Paleozoic and of the Upper Austroalpine Graz Paleozoic. Following a review of lithostratigraphic units of each area, a correlation is made between the Szendro-Uppony and the two Alpine structural units in terms of second order cycles within the Variscan megacycle. The close similarity between these Variscan sequences suggests their original proximity on the southern (Apulian) carbonate shelf of the Alpine-Dinaric arm of the Prototethys. From this position the Szendro-Uppony Paleozoic units (as part of the Gemer-Bukk domain or 'composite terrane') were displaced during Tertiary tectonic escape processes into the Pannonian region. The overlapping of Carnic Alps, resp. Graz Paleozoic facial characteristics in the Szendro-Uppony Paleozoic indicate that the Periadriatic Lineament was not a paleogeographic boundary during the Paleozoic (and the Mesozoic).
