“…Accordingly, T mean Jan. during 18-13.5 cal ka BP varied from -33 to -37°C, decreasing during the terminal stage of ice wedge growth. The 14 C dates and stable isotope compositions of ice wedges of the Seyakha yedoma were compared with yedoma exposures at three nearest sites in western part of Siberia: Marresale site (western coast of the Yamal Peninsula, 69.720ºN, 66.800ºE), Ery-Maretayakha (north of the Gydan Peninsula, 71.833ºN, 75.216ºE) (Forman et al 2002;Oblogov et al 2012;Streletskaya et al 2013), and Sabler Cape on the Taimyr Peninsula (74.550ºN, 100.533ºE) (Derevyagin et al 1999). Radiocarbon ages for these yedoma sections range from 36 to 10 cal ka BP.…”

Yedoma sediments with thick syngenetic ice wedges have been studied on the Yamal Peninsula, northwestern Siberia. The accumulation of yedoma strata occurred under alternating subaqueous-subaerial conditions, and three tiers of ice wedge were formed mainly on subaerial stages. The ice wedges and enclosing sediments were dated, revealing that the ice wedges were formed between 29 and 18 cal ka BP, while the enclosing sediments are generally older, possibly due to contamination with ancient material (especially in the central part of the yedoma). However, the termination of yedoma complex formation was dated not later than 13.5 cal ka BP. Stable oxygen-isotope data for the ice wedges indicate more severe winter climate conditions during 25–21 cal ka BP, when mean January air temperatures were at least 10°C lower that modern ones, favoring syngenetic ice wedge growth. Yedoma accumulation in the western part of northern Siberia does not support the existence here of an ice sheet during the LGM.

“…40-11 ka BP on the western Yamal Peninsula. In the ice wedges formed between 19.7 and 14.2 cal ka BP the δ 18 О values vary from −24.8 to −23.4‰(Streletskaya et al 2013). For the Ery-Maretayakha yedoma, the ice wedge which has been dated to about 26 cal ka BP is characterized by δ 18 О values from −22.6 to −24.6‰(Oblogov et al 2012).…”

Ice mounds are widespread cryogenic landforms that occur during freezing of water-saturated sediments and in ice segregation or ice injection with the formation of ice cores. Complex mechanisms of occurrence of these landforms have their own characteristics depending on the type of enclosing sediments, water and gas saturation, freezing rate, and other factors. Ice formation processes are often accompanied by explosions of the central part with the occurrence of negative landforms. In response to the widespread occurrence of perennially frozen gas-saturated rocks, these processes are accompanied by gas emissions, gas inflammation. and other, less intense gas shows. It is quite difficult in these conditions to determine the causes of the catastrophic phenomenon, to reconstruct the dynamics of the process, and to understand the role of gas-saturated fluids. In this paper, an attempt has been made to determine the ice formation conditions using isotopic techniques. The isotopic composition of ice can reflect the conditions of ice formation at the time of occurrence of ice mounds and its related possibility of participation of gas-saturated fluids from deep-lying gas-bearing horizons [Buddo et al., 2023, 2024]. The composition of stable isotopes δD and δ18O was determined for three ice mounds in the south of the Yamal Peninsula, where there were catastrophic explosions of ice mounds with the formation of large craters. The results of the study made it possible to reconstruct the conditions of ice mound occurrence and to determine different ice formation modes.
