Abstract. During the fieldwork in August 2024 (research station Vaskiny Dachi), we have made cryolithological descriptions of sections and collected samples for geochemical composition analysis and assessment of the mechanisms of matter transport to lakes from catchments impacted by thermos-denudation. These data will help in determining quantitative characteristics of transitional sediments and their re-distribution within areas adjacent to lakes. Keywords: thermo-denudation, thermocirque, Central Yamal, lakes, bottom sediments, heavy metals
