A section of the coastal Holocene with predominating clastic deposits and intercalated peat layers is described. The results of sedimentological investigations and the analysis of the micro- and mesofaunas are discussed with regard to the development of the lithofacies and the changes of the salinity. By means of a very large number of14C datings, the reliability of data from Phragmitespeat is checked, on the one hand, and a chronostratigraphic system is given for the investigated area, on the other.
