- Аннотация: TheMIS3 paleosol units comprise a prominent element of the loess-paleosol sequences throughout the EurasianLoess Belt. To the north of the loess regions, the findings of MIS3 paleosols were few: it was supposed thatgeomorphic processes related to the extensive ice cover of the Last Glacial Maximum destroyed the earlier soilmantle. Recently, much smaller extent of continental ice in the east of Northern Europe and ice-free WestSiberian Plain during MIS2 has been hypothesized, supposing preservation of MIS3 and earlier paleopedologicalrecords.Wediscovered in the center-north of European Russia (Upper Volga basin) andWestern Siberia (MiddleOb basin),MIS3 paleosolswithin the Late Pleistocene alluvial and lacustrine sequences and correlated the studiedprofiles on the basis of macro- and micromorphological characteristics and radiocarbon datings of the paleosolorganic materials. Paleosols are represented by hydromorphic profiles with Histic horizons and gleyic colorpattern. Conspicuously, they are developed in the well drained geomorphic positions, where modern soils arenon-gleyic. We suppose that the presence of permafrost was responsible for water logging and generation ofreductomorphic soil environment. We further hypothesize a northern zone of MIS3 soil mantle, comprised ofHistic and Reductaquic Cryosols different from synchronous Cambisols and Chernozems formed within loesssequences to the south.
