. Borisoglebsk Upland is considered an example of asecondary upland plain in the marginal zone of the last Middle Pleistoceneglaciation. Moraine hills and kames were reworked by glaciofluvial processesand incised by small fluvial forms later. Its postglacial surface driftcover is regularly defined as an undivided complex of mantle loams ofdominantly subaerial origin with characteristic cryogenic features andremnants of paleosols. However, some previous studies suggest that lakesedimentation played an important role in the postglacial history of theBorisoglebsk Upland. This paper presents results of a detailed investigationof postglacial sedimentary cover of the eastern part of the BorisoglebskUpland aimed to reconstruct the co-evolution of surface deposits, soil coverand geomorphic landscapes since degradation of the last Middle Pleistoceneglaciation about 150 ka (MIS-6). The study is essentially based on acomprehensive lithological, pedological and geocryological description ofpostglacial deposits in cores (hand or machine-driven) and open sections,systematic sampling for grain size analysis and selective sampling for 14C absolute dating and monoliths structural examination. The resultsindicate that most of the surface drifts in this feature consists ofstratified lacustrine deposits. Their Late Pleistocene age isstratigraphically confined by the underlying paleosols and incorporatedpeats of the Mikulino interglacial age (MIS-5) and several organic-richlayers within the lake sequence 14C dated to the Middle Valdaiinterstadial (MIS-3). Overlying mantle loams and colluvial deposits withcryogenic features and low organic matter content those facially substitutelacustrine sediments were attributed to the Late Valdai stadial (MIS-2).After the Mid-Holocene stabilization, relatively thin colluvial coveridentified by the increased amount of organic matter also deposited. Weconclude that lacustrine sedimentation is the primary Late Pleistocene agentthat transformed the initial glacial topography and most characteristic typeof lithodynamics of the eastern Borisoglebsk Upland.
