Preliminary stratigraphy of organic sediments at Narew, northern Podlasie, eastern Poland

Abstract

Pollen analysis was conducted for sediments from two organic series in the profile Narew-III. Age of the lower series (depth 72.0-80.5 m) was determined as an upper part of the Lower Miocene. The upper is the Quaternary series (depth 58.5-61.55 m) which represents two warm climatic oscillations, separated by a cool period of a stadial rank. The older warmer period probably corresponds to an interstadial. The stratigraphic rank of the younger warmer period could not be determined on the basis of a palynologic examination as the pollen record includes only the very end of a warming and a beginning of the following cooling.
