Indicators of paleocryogenic processes that disrupt the patterns of peatland autogenic development in the zone of seasonal freezing of rocks of Western Siberia

Abstract

Оn the data of detailed studies in 2003-2019 and dating of ¹⁴C, AMS, ²¹⁰Pb and ¹³⁷Cs peat sections of the zone of seasonal freezing of rocks of Western Siberia indicators of paleocryogenic processes were searched. The functional state of these peatlands was reconstructed as a response to continental climate changes. A system-evolutionary methodological approach to the search for disturbances of autogenic development of peatlands, dating of pairs of neighboring peat samples to identify the peat accumulation stopping, data on peat sections - analogues from the permafrost zone and data on paleoreconstructions of the Holocene climate of Western Siberia were used. This allowed indicators of paleocryogenic processes to be proposed. The use of these indicators will increase the objectivity of studying the climatic paleoreconstructions of the territory.
