LITHOLOGY OF THE PROFUNDAL SEDIMENTS IN SŁUPIAŃSKA BAY (WIGRY LAKE, NE POLAND) -- INTRODUCTION TO INTERDISCIPLINARY STUDY.

In this paper, a lithological study taking into account trace metals of the profundal sediments from Slupiañska Bay in Wigry Lake is presented. A profile 5.26 m long has sandy muds at the bottom and moving upwards layers of calcareous gyttja, lacustrine chalk, and again calcareous gyttja are present. The profile is continuous, typical for the sediments of NE Poland formed from Aller&3x00F8;de to recent time. The results of the lithological analysis were correlated with results of high-resolution seismic survey. The results together with radiocarbon dating are part of interdisciplinary complex re- search comprising paleobiological study of pollen, Cladocera, diatom successions and human activity, which will be published in successive papers.
