“…So, according to these data, it is possible to confirm that this period does not correspond to a lowstand but to a highstand with subaerial sediments deposited above the water level, those sediments having been inaccurately considered as being part of the Atelian sequence by some authors (e.g. Költringer et al, 2020;Kurbanov et al, 2020) but accurately interpreted by others Makeev et al, 2021). The proximity of the shoreline with certainly a hardly changing water level, explains the existence of several subaerial deposits with various ages that are sometimes separated by Caspian Sea sediments in the Northern Peri-Caspian area.…”

In the Northern Caspian Sea basin, ages range between 43.9 and 39.5 cal kyr BP (Bezrodnykh et al, 2017;Yanina et al, 2018), and some authors proposed that the younger ages obtained on the coastal samples, no more represent the Atelian lowstand but a Khvalynian highstand Makeev et al, 2021). The different consideration of subaerial coastal samples by the authors is expressed in Fig.…”

“…However, recent stratigraphic comparison of key sections based on litho-and pedostratigraphy, MS, GS, elemental and mineral composition, and luminescence dating in western Ciscaucasia (Azov Sea region and Stavropol Upland) showed that the three phases of soil formation within the S1 pedocomplex are probably a regional pattern and approximately corresponding to the warm stages within MIS 5-5a, 5c, and 5e (Mazneva et al, 2021). In addition, a detailed study of the depositional environment and pedostratigraphy on three paleosols of the MIS 5 pedocomplex of the Srednaya Akhtuba section was also conducted in nearby Lower Volga region further east of Azov Sea, with OSL ages ranging from 112.6 ± 5.4 to 68.3 ± 4.2 ka (Makeev et al, 2021). Especially the age of 68.3 ± 4.2 ka, obtained from the loess unit overlying the uppermost paleosol (corresponding to the S 1 SS 1 in our Beglitsa section) of three soils (Yanina et al, 2017), is much older than the previously reported radiocarbon and OSL ages from the S 1 SS 1 of the Beglitsa section.…”

Loess-paleosol sequences are the most intensively studied terrestrial archives used for the reconstruction of Late Pleistocene environmental and climatic changes in the Azov Sea region, southwest Russia. Here we present a refined chronostratigraphy and a multiproxy record of Late Pleistocene environmental dynamics of the most complete and representative loess–paleosol sequences (Beglitsa and Chumbur-Kosa sections) from the Azov Sea region. We propose a new chronostratigraphy following the Chinese and Danubean loess stratigraphic models that refines the subdivision of the Last Interglacial paleosol (S1) complex in two Azov Sea sites, resolve the uncertainty of the stratigraphic position of the weakly developed paleosol (L1SSm) in Beglitsa section, and allow for direct correlation of the Azov Sea sections with those in the Danube Basin and the Chinese Loess Plateau. More importantly, it may serve as a basis for better constraining local and regional chronostratigraphic correlations, and facilitate the interpretation of climatic connections and possible forcing mechanisms responsible for the climatic trends in the region. In addition, a general succession of environmental dynamics is reconstructed from these two vital sections, which is broadly consistent with other loess records in the Dnieper Lowland and Lower Danube Basin, demonstrating similar climatic trends at Glacial–Interglacial time scales. Furthermore, our results have important implications for the chronostratigraphic representativeness of Beglitsa as a key regional loess section and for the reconstruction of the temporal and spatial evolution of Late Pleistocene climate in the Azov Sea region.

The Sukhaya Mechetka is the most important Middle Paleolithic site in the Eastern Europe. The paper presents the analysis of the section, including its cultural layer, in the context of stratigraphy and paleogeography of the Lower Volga River region. The structure of the section represents 11 main stages of sedimentation and paleogeographic evolution of the site territory, which are closely related to global and regional changes in the climate and the level of the Caspian Sea. The base of the section reflects the stage of a river existence on the territory of the site that flowed into the Volga River estuary, formed by the Early Khazarian transgression of the Caspian Sea at the end of the Middle Pleistocene (MIS 6). A long continental period of evolution under multi-directional climate fluctuations of different amplitudes from the Mikulino interglacial (MIS 5e) till the Late Valdai glacial epoch (MIS 2) is reflected in the middle part of the section. The Late Khazarian and Hyrcanian transgressive basins (MIS 5), as well as the Paleo-Khvalynian stage (MIS 3) of the Caspian Sea did not reach the latitude of Sukhaya Mechetka. The stage of Early Khvalynian transgression (MIS 2, 16 190 ± 200 years ago) during the degradation of Ostashkovo glaciation is expressed in the upper part of the section. Three paleosoils have been found that reflect the warming periods of the MIS 5 stage and are related to its 5e, 5c and 5a sub-stages. The middle paleosoil contains a cultural layer assigned to the Micoquian/KMG community of Northern Eurasia. The climate was moderately warm during the Neanderthal settlement of the territory, steppe landscapes dominated the interfluve, and the forests grew in the balka. The Hyrcanian transgression of the Caspian Sea with an estuary in the Volga River valley predetermined a high erosion basis and the formation of a balka with a wide bottom and gentle banks. A permanent fresh watercourse attracted mammals which were an object of hunting for ancient men. All this, obviously, became a basis for the organization of settlement in the Sukhaya Mechetka balka. Correlation of the section with detailed studied loess-soil sections of the Lower Volga River region makes it possible to determine the age of its cultural horizon in between 97-110 thousand years ago.
