Abstract
The radiocarbon dates for the Bryansk paleosols in different sections of the Central Russian Upland, Alexandrov quarry, Zheleznogorsk, KBS-13, Taneyev quarry, Fatyanovka, Monastyrshchina, Kostenki-14, were obtained for different carbonaceous materials including sum of humic acids, pedogenic carbonates, charcoal, and bone collagen. The morphogenetic analysis of the paleosols including micromorphological observations was also conducted. Palaeosolos are meadow-carbonate or sod-carbonate with evidence of permafrost processes. The interval of the Bryansk paleosols development in the Late Pleistocene was between 33–26 ka BP, formed over 5–7 ka. The majority of radiocarbon dates obtained for humic acids and pedogenic carbonates from the Bryansk paleosols are rejuvenated. This fact was explained by the existence of the soils on the surface for a long time at the maximum of glaciation in MIS 2. The beginning of the last phase of loess accumulation at the Central Russian Upland was 17–15 ka BP.
