First data on the radiocarbon age of the Atelian deposits in the North Caspian Region

Chronology of the Late Pleistocene Caspian Sea hydrologic changes: A review of dates and proposed climate-induced driving mechanisms

“…Kurbanov et al, 2020;Svitoch and Makshaev, 2020;Költringer et al, 2020; Table 1). 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.…”

“…Dating of subaerial sediments outcropping in the Lower Volga and assigned to the Atelian, provided ages between 80.0 and 28.0 kyr using TL method (Shahovets, 1987, while by OSL they are between ca 70.0 and 19.0 kyr (Kurbanov et al, 2020;Költringer et al, 2020). Calibrated radiocarbon dates from Northern Caspian Sea basin where Atelian sediments have been identified in seismicacoustic profiles and sediment cores, ranged from ca 44.4 to 39.3 cal kyr BP (Svitoch et al, 2008b;Bezrodnykh et al, 2017;Yanina et al, 2018Yanina et al, , 2020. proposed the Atelian lowstand occurred between ca 75.0 and 40.0 cal kyr BP and considered younger sediments from the Lower Volga as no more representing the Atelian period, while Lavrushin and colleagues (2014) have recognised two stages: (i) an old and long-lasting palaeoAtelian between ca 130.0 and 60.0 kyr, and (ii) a short-term event at ca 20.0 cal kyr BP.…”

“…In the same paper, Sorokin and collaborators separated the Hyrcanian samples from those of the Early Khvalynian. However, one of the ages at 48.5 cal kyr is considered as belonging to the Early Khvalynian highstand or to the Hyrcanian one depending on the authors (Sorokin et al, 2014;Bezrodnykh et al, 2017), and all ages together form a cluster from at least ca 55.2 to 42.1 cal kyr BP (Fig. 5a Nevertheless, authors who obtained 14 C ages for Hyrcanian highstand in the Northern Caspian Sea basin (Sorokin et al, 2018;, acknowledged that the ages are close to the limit of 14 C method.…”

Environmental Variability Of The Ponto-Caspian And Mediterranean Basins During The Last Climatic Macrocycle

“…The end of the Khazarian stage in the Caspian Sea evolution was marked by a deep regression. The estimates of the regression amplitude vary widely -from -43 m (Badyukova 2016), and -53 m (Leontyev et al 1977), to -100 m (Bezrodnykh et al 2017) and -140 м (Lokhin and Mayev 1990).…”

“…In the depositional series of the Northern Caspian, the Atelian interval is represented by paleodepressions and erosional landforms, which are distinctly visible in the seismic stratigraphic profiles (Bezrodnykh et al 2017). As appears from the composition of organic remains, the period was characterized by the presence of lakes with fresh or brackish water and wetlands.…”
