The Last Deglaciation

Chronology of the Last Deglaciation in the Southeastern Baltic Region on the Basis of Recent OSL DatesThe study of the deglaciation chronology in the south-eastern Baltic Region belonging to the outer zone of the last Pleistocene glaciation has a long history. The Finnish investigator H. Hausen (1913) who worked in the north-western portion of the East-European Plain at the beginning of the 20thcentury was the first to attempt a reconstruction of the course of glacial retreat during the last glaciation. At that time investigators had no physical dating methods and the time scale based on varvometric method, introduced by the Swedish geologist G. de Geer (1912) who divided the deglaciation history of Scandinavia into Daniglacial, Gotiglacial and Finiglacial, each of which had different palaeoglaciological conditions. During last decades different dating methods, including14C, ESR, luminescence methods and10Be techniques have been used, but they could not help essentially improve the existing stratigraphical charts and many problems of topical interest in the history of deglaciation have not been solved yet. During last years the first two authors have studied the suitability of OSL method for the geochronological purposes, paying the most attention to the waterlaid sediments. In the first step they have found the most promising genetical varieties of glaciofluvial sediments (glaciofluvial deltas and sandurs) and in this paper they widened the study area to all three Baltic states with close cooperation with Latvian and Lithuanian colleagues. The obtained results demonstrated, that not all mineral grains in the uppermost glaciofluvial and glaciolacustrine sediments were fully bleached during the last deglaciation. Probably the older sediments also influenced to the luminescence results. It means, that stratigraphic conclusions based on single dates or their small sets are inadmissible and in each case luminiscence dating requires a verification using other methods.

Erosion Intensity

Recent decades in the north of the East European Plain have been characterized by significant changes in climate and land use/cover, especially after the collapse of the USSR in 1991. At the same time, the hydrological consequences of these changes, especially changes in erosion processes and river sediment load, have been studied insufficiently. This paper partially covers this existing knowledge gap using the example of the Vyatka River basin. Draining an area of 129,000 km2, the Vyatka River is among the largest rivers in the boreal forest zone of European Russia. Cultivated land occupies about one-fifth of the river basin area; about three-fourths is covered by taiga forest vegetation. The results of state long-term hydrometeorological monitoring and information on land use/cover made it possible to reveal contemporary (since the 1960s) hydrological and erosion-intensity trends and their drivers within the greater (96%) part of the river basin. There has been a statistically insignificant increase in water discharge in the Vyatka River basin during recent decades. This is due to a statistically insignificant increase (for the entire basin studied) in the spring snowmelt-induced floodwater flow and a statistically significant rise in the discharge in the year’s warm and cold seasons. The main reason for the detected trends is increased precipitation, including heavy rainfall during the warm season. In contrast to this, the total annual suspended sediment load of the river (especially that which was snowmelt-induced) and, consequently, soil/gully erosion intensity have experienced a significant decrease in recent decades (up to 58% between 1960–1980 and 2010–2018). Land-use/-cover changes (a reduction of cultivated land area and agricultural machinery, a decline of livestock in pastures) following the collapse of the Soviet Union are considered the main reasons for this decrease. The most noticeable changes in water discharge, suspended sediment load, and erosion intensity were observed in the most agriculturally developed southwest and south parts of the Vyatka River basin. All the above trends may be considered with a high probability to be representative for the south sector of the taiga zone of the East European Plain.

The small group of early ceramics was found between the 1930s and 1990s, but was previously underestimated as a source that points directly to the origins of ceramic production in the boreal forest zone c. 5500–5000 BC. The Kargopol type ceramics demonstrate very archaic technological traits: a straight rim with round holes below the rim and clay paste with sand temper. This type of ceramics had a wide distribution and was made uniformly, at least concerning vessel capacities and basic decoration patterns, probably reflecting the birch bark vessel features. We recognize this phenomenon as key to understand how the process of ceramic production emerged in the zone of Russian boreal forest.

History Of

The material in the article contains biographical information from the life and scientific activity of the doctor of geological and mineralogical sciences, professor, academician Academy of Sciences of the USSR A.D. Arkhangelsky. A wide range of the scientist is shown and a description of the main directions of research in the field of regional geology, fauna and stratigraphy of the Paleogene and Upper Cretaceous deposits of the Volga and Central Asia, lithology and paleography, issues of tectonics and the relationship of gravitational and magnetic anomalies with the geological structure of the territory of the USSR is given. The main attention is paid to his work in the study of the geology of oceans and seas. The main contribution of the scientist to the study of Mesozoic bauxites, their structure and mineral composition is described. On this basis, the scientist developed and substantiated a new sedimentary theory of their formation. This theory opened the possibility for geologists to approach the study of bauxite as sedimentary rocks; this played an important role in the search for new deposits of this valuable mineral. The complex of geological and geophysical work carried out by him on expeditions along the East European Plain provided an answer to important questions about the distribution of oil, coal and iron ores on the territory of the Russian Platform. Much attention was paid to the study of the geology of the Black Sea. Processing materials collected by a hydrographic expedition and a comparative study of the columns of the Black Sea silt and oil-bearing sediments of the Crimean-Caucasian region led the scientist to important conclusions about the conditions of accumulation of oil-producing suites. Long-year research A.D. Arkhangelsk sediments of the Black Sea, their lithology, geochemistry, structure, subsequent changes and deformations were summarized in a number of works, among which are “Conditions for the formation of oil in the North Caucasus” (1927), “Geological history of the Black Sea” (1932), “Geological structure and the history of the development of the Black Sea“ (1938), written together with N.M. Strakhov. In 1926—1928 Arkhangelsky lead the field geological survey work on the Kerch Peninsula for the study of oil fields.
