| Abstract: | The Late Cretaceous to Early Miocene strata of the Carpathian foreland basin in southern Moravia (Czech Republic) are represented
by a variety of facies which reflects the evolution of the foreland depositional system. However, because of the intensive
deformation and tectonic displacement and the lack of diagnostic fossils the stratigraphic correlation and paleogeographic
interpretation of these strata are difficult and often controversial. In order to better correlate and to integrate them into
a broader Alpine–Carpathian foreland depositional system, these discontinuous and fragmentary strata have been related to
four major tectonic and depositional events: (a) formation of the Carpathian foreland basin in Late Cretaceous which followed
the subduction of Tethys and subsequent deformation of the Inner Alps-Carpathians; (b) Middle to Late Eocene transgression
over the European foreland and the Carpathian fold belt accompanied by deepening of the foreland basin and deposition of organic-rich
Menilitic Formation; (c) Late Oligocene to Early Miocene (Egerian) uplifting and deformation of inner zones of the Carpathian
flysch belt and deposition of Krosno-type flysch in the foreland basin; and (d) Early Miocene (Eggenburgian) marine transgression
and formation of late orogenic and postorogenic molasse-type foreland basin in the foreland. These four principal events and
corresponding depositional sequences are recognized throughout the region and can be used as a framework for regional correlation
within the Alpine–Carpathian foreland basin.
