“…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.…”

“…Сделав анализ данных сторонников и противников такой модели, авторы провели на севере Западной Сибири своё исследование. Реликтов ледников они не обнаружили; ими было выявлено господство процессов глубокого промерзания земной коры в квартере на фоне саморазвития речной сети [12,13], и тогда их усилия были направлены на поиск преобразованных криолитогенезом палеопочв, которые в отсутствие ледникового покрова так или иначе в этой зоне тогда могли иметь место. Вскоре они были установлены в восточной части Сибирских Увалов -вверху и в центре 30-40-метровой аллювиальной террасы (её кровля здесь имеет отметки 110-130 м).…”

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.

“…Many field investigations and remote-sensing operations were completed by multiple generations of researchers, providing a valuable baseline for future studies. The results of studying the Nadym River and adjacent areas, combined with other data, served as a basis for a classification of the Quaternary deposits in Western Siberia (Maslennikov, 1998;Sedov et al, 2016;Sheinkman et al, 2016;Rusakov et al, 2018). Nevertheless, the current geological map (Faibusovic and Abakumova, 2015) still has unresolved issues that are highlighted as new geological and geomorphological data are obtained.…”

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

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.

“…Study of insects in Quaternary deposits of West Siberian Plain began in 1970s (Kiselev, 1973(Kiselev, , 1988 and now significant material is accumulated from northern and central parts of West Siberian Plain and the Urals (N 70° -57°). More than 130 sites with insect remains of different ages from Pleistocene to Holocene are known from this territory (Zinovyev, 2008(Zinovyev, , 2011Sheinkman et al, 2016;Rusakov et al, 2019). In a course of the expedition trips 2012-2014 in southern part of West Siberian Plain insect remains were found on banks of rivers Ob, Chik, Suzun, Chumysh, Alei, Ustianka and Kizikha (Tsepelev et al, 2013;Tshernyshev et al, 2013;Gurina et al, 2016Gurina et al, , 2018Gurina et al, , 2019Zinovyev et al, 2016).…”

Two sites with insect remains were found in an exposure on the bank of Kizikha river, in the Rubtsovskii District of the Altaiskii Krai of Russia, Kizikha-1 with radiocarbon age 13455±150 14 C BP (SPb-1347), and Kizikha-2 with the age 26094±400 14 C BP (SPb-1418). This period is coincides with Sartan stadial and Kargin interstadial (MIS 2 and MIS 3). This is the southernmost late Pleistocene insect bearing deposit found in West Siberia. The fragments in both sites are represented mainly by Coleoptera. Beetle fauna from the site Kizikha-1 is represented by 34 species from 9 families. The majority of fragments belong to weevils and ground beetles. 28 species from 8 families are found in Kizikha-2 site, the majority of fragments belong to Carabidae. 7 species found in the sites, Dyschiriodes rufimanus, Cymindis cf. rostowtzowi (Carabidae), Cidnopus cf. parallelus, Pristilophus punctatissimus (Elateridae), Hemitrichapion alexsandri (Brentidae), Paophilus albilaterus and Otiorhynchus sushkini (Curculionidae), are recorded in Pleistocene deposits for the first time. Sub-fossil insect assemblages of the two sites coincides with the late Pleistocene "Otiorhynchus-type" sub-fossil insect fauna from southeastern part of West-Siberian Plain (Zinovyev, 2011; Legalov et al., 2016) with characteristics as follows: dominance of steppe species, presence of halophile species, lack of forest species. Most of these species are absent in the contemporary regional fauna. The complex of eastern species and presence of endemics of Altai-Sayan Mountain system is also characteristic to the both studied sites. Specifics of the deposit assemblages in comparison with the other late Pleistocene fauna of West Siberian Plain is in high share of meadow species that could be explained by taphonomic condition of sedimentation or microclimatic conditions caused by close location to Altai mountains. Analysis of sub-fossil insect fragments showed that open landscapes with zonal steppe and sparse meadow vegetation near rivers and in depressions were typical for this area. In comparison to contemporary conditions climate was dry and cold, but Kizikha-2 (end of MIS 3) was formed in more mild climate conditions than Kizikha-1 (end of MIS 2). Results gained from Kizikha-1 and Kizikha-2 sites are complementing data on latitudinal-zonal distribution of beetles found in late Pleistocene deposits in West Siberian Plain.
