Abstract

The Muschelkalk of southern Hungary consists of Wellenkalk carbonates, Coenothyris beds and ooidal, dolomitised sequences. The depositional environment was a homoclinal carbonate ramp, which succeeded a clastics covered terrain of the Early Triassic pre-ramp phase. Major sediment reworking processes include storm activity and slumping on the gentle slopes. The lithotypes and sedimentary structures are very similar to those of the epicontinental of the German Triassic sequences, especially to the Silesian ones. The differences are probably related to the shallower water depth, more significant restriction and the different palaeolatitude. The thick Middle Muschelkalk evaporites and a part of the German Upper Muschelkalk appear to be missing in Hungary. In the Late Triassic the ramp became covered by clastics (clastics buried ramp phase).
