Abstract
Both the Drauzug (Italy, Austria) and the Transdanubian Mountains (Hungary) show great differences in facies compared to the geological units that presently surround them, i.e. proximal facies contrast with distal facies in the Permo-Triassic. Lower Liassic strata in the Drauzug and the Transdanubian Mountains indicate an extensional regime causing typical structural features such as tilted blocks, fault scarps, and drowned carbonate platforms. The Permo-Mesozoic facies zones provide markers for the paleogeographic fitting of the Drauzug and the Transdanubian Mountains with areas today lying some 300-400 km to the west: the Drauzug corresponds to the Lombardian basin and the westernmost part of the Northern Calcareous Alps while the Transdanubian Mountains correspond to the westernmost part of the Lombardian basin, the Trento platform, and the Belluno trough. The Drauzug and the Transdanubian Mountains (together with the South Alpine realm) were displaced to the east along strike-slip faults during the Middle Jurassic to Early Cretaceous opening of the Central Atlantic and Ligurian-Piemont oceans and the simultaneous subduction of the Vardar ocean at the eastern margin of Apulia. Finally in Late Oligocene and Miocene times the Southern Alps were displaced back to the west along the dextral Periadriatic fault system.
