“…The available 14 C date supports an attribution of the upper pedocomplex (layer VIII) to the second half of MIS 3 (Sedov et al, 2016; Sheinkman et al, 2016). This period corresponds to the Karginsky interstadial/thermochron in the West Siberian stratigraphic scheme.…”

“…We focused our research on the upper parts of the section, which provide a detailed sequence of Late Quaternary sediments and paleosols with well-preserved organic materials. Some particularities of this sequence have been published recently, including data on the MIS 3 paleosol (Sedov et al, 2016), fossil insects from the MIS 5 unit (Zinoviev et al, 2016), and comparison of the paleosols of Belaya Gora with eastern European analogues (Rusakov et al, 2018). Here, we present for the first time integrated sedimentological, paleopedological, and paleobotanical records, which provide new insight on the regional paleoenvironmental history and allow for possibilities for correlation on continental and global scales.…”

Recent revision of the Pleistocene glaciation boundaries in northern Eurasia has encouraged the search for nonglacial geological records of the environmental history of northern West Siberia. We studied an alluvial paleosol-sedimentary sequence of the high terrace of the Vakh River (middle Ob basin) to extract the indicators of environmental change since Marine Oxygen Isotope Stage (MIS) 6. Two levels of the buried paleosols are attributed to MIS 5 and MIS 3, as evidenced by U/Th and radiocarbon dates. Palynological and pedogenetic characteristics of the lower pedocomplex recorded the climate fluctuations during MIS 5, from the Picea-Larix taiga environment during MIS 5e to the establishment of the tundra-steppe environment due to the cooling of MIS 5d or MIS 5b and partial recovery of boreal forests with Picea and Pinus in MIS 5c or MIS 5a. The upper paleosol level shows signs of cryogenic hydromorphic pedogenesis corresponding to the tundra landscape, with permafrost during MIS 3. Boulders incorporated in a laminated alluvial deposit between the paleosols are dropstones brought from the Enisei valley by ice rafting during the cold MIS 4. An abundance of eolian morphostructures on quartz grains from the sediments that overly the upper paleosol suggests a cold, dry, and windy environment during the MIS 2 cryochron.

“…Nowadays, due to the increasing availability of digital elevation models, remote mapping of glacial relief features has become the standard method across the world (Clark et al, 2004;Glasser et al, 2008;Sharpe et al, 2010;Fredin et al, 2012;Atkinson et al, 2014;Norris et al, 2017). Based on modern spatial data, a detailed map for the "British Isles territory and coastal zone" (BRITICE-2) is available for digital study and analysis and was updated (Clark et al, 2018).…”

Lithological and geomorphological indicators of glacial genesis in the upper Quaternary strata, Nadym River basin, Western Siberia

et al. 2020

Abstract. Analysing the genesis of Quaternary sediments is important for understanding the glaciation history and development of marine sediments in the northern part of Western Siberia. The problem is relevant since there is no consistent concept of the Quaternary sediment genesis in the north of Western Siberia. The formation of sediments is associated with marine, glacial and interglacial sedimentation conditions. The research objective is to identify the persistent features characterising the conditions of sedimentation and relief formation using the Nadym River basin as an example. The best method for studying this problem is a comprehensive analysis of the lithological, chronostratigraphic, petrographic and geomorphological studies of the Quaternary sediment upper strata. This study provides data from the analysis of the basic characteristics of quartz grains at the site. The rounding and morphology of the quartz grains provide evidence of possible glacial processing of some of the site strata. A petrographic study of selected boulder samples was performed. Some of them, by the shape and presence of striation, can be attributed to ice basins. The first use of a detailed digital elevation model applied to the study area made it possible to identify specific relief forms that could very likely be created during glaciations. Based on the analysis, we propose to consider the vast lake alluvial plains in the Nadym River basin as periglacial regions. This idea lays the lithological framework for understanding the reasons for the formation of the modern landscape structure. The materials and descriptions provided are of interest to researchers of Quaternary sediments, topography, vegetation and soil cover, particularly researchers engaged in revising the history of the natural environment development in the north of Western Siberia.

“…Почвы МИС-3 давно используются для индикации пород лёссового пояса, но севернее они мало изучены, и существенно расширить их информационную базу позволили криотрасологические индикаторы. Преобразованные криолитогенезом почвы МИС-3 были выявлены в Верхнем Поволжье и на севере Западной Сибири [9][10][11]13], и в последнем случае результаты особо важны: значительной частью исследователей здесь была принята модель покровного ледника, и они были уверены в нереальности в появления в этой зоне палеопочв. Сделав анализ данных сторонников и противников такой модели, авторы провели на севере Западной Сибири своё исследование.…”

Rock freezing affects the soil complexes under maximal temperature gradients and forms a set of specific cryotrasological features in the solid soil matrix. When preserved these features serve as direct or indirect indicators of the past cryogenic conditions. Transformation of soil material on macro- and microscale belongs to the direct indicators whereas gleying in the well-drained positions, conditioned by the permafrost waterlogging is an indirect indicator. A variety of these features observed in the paleosols to the north of the European and West Siberian Loess belt was used by the authors to reconstruct the cryogenic environments of the late Pleistocene.
