This issue considers new and only partially previously published data on the Late Pleistocene landscapes and deposits of the Moscow glaciation marginal zone, which has experienced dynamic periglacial conditions during the Valdai epoch. The manuscript is arranged as a guidebook for the Valdai Perglacial Field Symposium, which was held on 27–30 August 2023 embracing the Upper Volga and Vladimir Opolie regions in the center of the East-European Plain. The field route captured the unique landscapes of Borisoglebsk Upland and Rostov Lowland, Volga Valley terraces and surrounding moraines, Shikhobalovo and Suzdal plateaus. Reconstructions of environmental settings of the former periglacial zone accomplished by several scientific teams are presented based on the studies of lacustrine and palustrine paleoarchives, palimpsest records of cover deposits, and fluvial channel morphology and alluvial infills. The structure of postglacial sedimentary cover embedding relict cryogenic phenomena and paleosols, both buried and surface, is examined. Thus, the origins and age of mantle (loess-like) loams and the input of cryogenic relicts on the soil cover spatial organization and paleosol structure are discussed, and problems of the paleohydrological development of the Upper Volga Basin are raised. This issue targets specialists in the fields of Quaternary geology and paleogeography, paleopedology and soil geography, geomorphology, cryolithology, and paleolimnology, as well as undergraduates and graduates studying Earth Sciences.

Stop 2. Glacial Inheritance vs Postglacial Metamorphoses Of Borisoglebsk Upland Interfluves

Detailed analysis of the E Borisoglebsk Upland suggests that most of the surface drift materials initially interpreted as polygenetic mantle loams were likely formed by continuous postglacial lacustrine deposition. Major arguments for such genetic interpretation are the dominance of fine-grained fractions; clear and texturally contrast multiscale lamination (up to five levels of laminae thickness); mottled ...

General Stratigraphy Of Postglacial Sedimentary Cover Of Vladimir Opolie

At the southernmost range of mantle loams distribution, so-called loess islands (Makeev, 2012) show some resemblance to the profound loess-paleosol sequences of the extra-glacial areas (Velichko, 1990). They commonly occupy relative topographic highs that inherit pre-Quaternary erosional uplands capped with thin glacial tills (Fig. G). In contrast, surrounding lower-lying outwash plains are majorly devoid of ...
