Erdei, B.; Bruch, A. A.: A climate analysis of Late Oligocene (Egerian) macrofloras from Hungary

There are numerous works treating the stratigraphy and tectonic evolution of the Palaeogene Basin (BÁLDI 1965,1973, 1983, 1998, BÁLDI and SENFS 1975, BÁLDI et al. 1999, CSONTOS et al. 1992, KÁZMÉR and KOVÁCS 1985, NAGYMAROSY 1990). Probably the drift of the Pelso unit in SW-NE direction along the Balaton and Mid-Hungarian lines (fault system) accounts for the recent distribution of the Intra-Carpathian Palaeogene sedimentary basins which extends from Slovenia through Hungary to Slovakia (NAGYMAROSY 1990). Stratigraphy of the Hungarian Oligocène is showed by Figure 2. Localities in the Bükk Mountains (NE Hungary) The most abundant Late Oligocène (Egerian) fossil plant assemblage was recorded from the clay-pit of the Eger-Wind brickyard, the well-known classic macrofaunal (molluscs, corals, sharks) and large foraminiferal locality where the Egerian stratotype section (Paratethys regional stratigraphy) was designated. Besides, in the close vicinity of the locality at another surface section (near NovajNyárjas) an additional "facio-stratotype" was indicated (BÁLDI and SENES 1975, BÁLDI et al. 1999). In this way an even greater importance is attached to the fossil assemblage. Leaf remains of the Eger-Wind locality were exposed from marine, Fig. 1.
