Direct AMS radiocarbon age of the MIS 3-2 thin composite wedges from Batagay Upper Sand
We used AMS 14 C dating to determine the age of the composite wedge formation in the Batagay Upper Sand unit. The composite wedges are interpreted as syngenetic structures; they have grown vertically upward with aggradation of the host sandy deposits. The formation of composite wedges in Upper Sand commenced no later than 38.3 cal ka BP and stopped not earlier than 25.5 cal ka BP in the northwestern part of the slump. In the formation of ice wedg…
Early Holocene Oxygen Isotope Chronologies (11,267–6420 Cal Bp) From Ice Wedge at Chara, Transbaikalia
Accelerator mass spectrometry radiocarbon (AMS 14 C) dating was used for determining the age of wedge ice. It has been found that between 11,270 and 6420 cal BP, or the Greenlandian and Northgrippian stages of the Holocene, ice wedges grew syngenetically in sandy deposits with gravel in the Chara River valley. The variations of δ 18 O values in the ice wedges are about 8‰, from –25.5‰ to –18.8‰. Based on the stable isotope composition of ice wedg…
Chronologies of active growth of ice wedges and Middle Holocene palaeoclimate at Lorino site, Chukchi Peninsula, easternmost Siberia
AMS radiocarbon ages of organic matter from ice wedges and enclosing peat were determined for the polygonal peatland at the Lorino site on the eastern coast of the Chukchi Peninsula. The study’s goal was to fill a knowledge gap about the dynamics of polygonal peatlands with ice wedges and winter climate conditions during the Holocene in this easternmost region of the Russian Arctic. It has been found that peatland accumulated during the Younger D…
Mis 3–2 Paleo-Winter Temperature Reconstructions Obtained From Stable Water Isotope Records of Radiocarbon-Dated Ice Wedges of the Batagay Ice Complex (Yana Upland, Eastern Siberia)
The recently formed Batagay mega-thaw slump exposes permafrost deposits to a depth of up to 92 m below ground surface and provides insight into the climate record in the region of the most severe continental climate in the Northern Hemisphere. Radiocarbon and stable isotope data were obtained to verify the age of ice wedges in the Batagay yedoma (upper Ice Complex in the local cryostratigraphy), and to deduce paleoclimate information. A millennia…
