Abstract

The changes in the Paleocene/Eocene boundary were studied in the sub-CCD flysch facies of the Bílé Karpaty Unit at Blatnička. A detailed taphonomic and sedimentologic analysis of selected turbidite rhythm revealed a bioturbation of at least upper 11 cm of turbidite marls and indicated the CCD drop for a relatively long period after deposition of the turbidite. Preliminary results of the biostratigraphic study (calcareous nannofossils, aglutinated foraminifera) enabled to assign the studied 17 m thick section to upper part of the Paleocene/Eocene boundary interval. Palynologie study evidenced the presence of Apectodinium, sp. acme. Preliminary geochemical analysis evidenced oxygenated environment and increasing redox potential trend up the section.
