Heterogeneous ices in ice wedges structure on the Pur-Taz interfluve peatlands of the north of West Siberia

open access: yesЛëд и снег, 2020
Structure of arctic peatlands with massive ice and structure-forming ice were studied in drained lake («khasyrey») of the Pur-Taz interfluves (the north of West Siberia). The period of accumulation of two-meter thickness of the peat was established to be

Bayesian age models and stacks: combining age inferences from radiocarbon and benthic δ18O stratigraphic alignment [PDF]

open access: yesClimate of the Past, 2023
Previously developed software packages that generate probabilistic age models for ocean sediment cores are designed to either interpolate between different age proxies at discrete depths (e.g., radiocarbon, tephra layers, or tie points) or perform a ...

Structure and formation of ice-ground veins of the second lake-alluvial terrace in the North of Gydan in the late Neopleistocene–Holocene

open access: yesЛëд и снег, 2019
The syngenetic ice and ice-ground composite veins in khasyrey (alas) and interalas plateaus were studied on the second lake-alluvial terrace located in the North of the Gydan Peninsula near the village of Gyda. On the basis of the radiocarbon dating, the

Radiocarbon dating and its applications in Chinese archeology: An overview

open access: yesFrontiers in Earth Science, 2023
Radiocarbon dating is a well-established chronometric technique that has been widely employed in Chinese archeology since the first radiocarbon laboratory started operating in the Institute of Archaeology at the Chinese Academy of Sciences in 1965.

Changes in the radiocarbon reservoir age in Lake Xingyun, Southwestern China during the Holocene.

open access: yesPLoS ONE, 2015
Chronology is a necessary component of paleoclimatology. Radiocarbon dating plays a central role in determining the ages of geological samples younger than ca. 50 ka BP.
