210 Pb DATING OF YOUNG HOLOCENE SEDIMENTS IN HIGH-MOUNTAINS LAKES OF THE TATRA MOUNTAINS

Abstract

Abstract: Topmost sediments in two oligotrophic lakes of the High Tatra Mountains were studied in terms of sedimentological characteristics and 210Pb dating. An alpine lake sediments are important source of information on geomorphic process activity in glacial catchments. Two different sediment transfer models are represented. In Morskie Oko lake basin majority of extreme, short lasting geomorphic events triggered on the surrounding slopes are registred in lake sediments (minerogenic laminae), while in Zelene Pleso lake only an effect of pro-longed flooding periods are to be seen. The sedimentation rates in both lakes are similar. Key words:
