Abstract (in english)
   Refined foraminifera- and nannoplankton-zonations triggered the start of an interdisciplinary study of selective fine-clastic outcrops in the Grünbach-Neue Welt Gosau-Group. The Coal-Bearing Series at Maiersdorf can be assigned to the Globotruncana elevata planktonic foraminifera zone, i.e. late Early Campanian. Coarsly speaking, the Inoceramus-Marl of the western part of the Grünbach Gosau shows Late Campanian age (nannozones UC15d, UC16 sensu BURNETT, 1998), while in the area east of Grünbach Schule railway station (surroundings of Dörfles and Zweiersdorf) Early Maastrichtian ages prevail (nannofossil zones UC18-?UC19, respectively Gansserina gansseri planktonic foraminifera zone); also Late Maastrichtian parts of the Inoceramus-Marl are likely to occur. The palynomorpha are dominated by angiosperm pollen. All our samples from the Zweiersdorf-Formation can be assigned to the nannoplankton zone NNTp4 of Danian age.
   All Late Cretaceous fine clastic samples are characterized by high contents of calcite, also dolomite is conspicuous. In the Zweiersdorf-Formation, however, the calcite content is low and dolomite is missing. In the latter muscovite, feldspar, phyllosilicates and paragonite are dominating, also smectite is common, whereas illite is rare. Within the Inoceramus-Marl the smectite content is elevated in the Late Campanian samples compared to the Early Maastrichtian ones, where the contents of kaolinite and chlorite are more conspicuous. The Coal-Bearing Series show only relatively small amounts of smectite and phyllosilicates, while the illite content is relatively higher
