- Аннотация: Syngenetic ice wedges, isotopic composition, radiocarbon age and pollen spectra of surrounding deposits in which they are found were analyzed during long-term study of “Bely Klyuch” key site on first terrace of Chara River (720 m a.s.l.) in Northern Transbaikalia. It was ground that ice wedges are Holocene age and were forming between 10 to 7.5 ka 14C BP. This period identified as first half of Holocene optimum for south Siberia. The isotopic composition of ice wedges, river and lake waters was specified. The isotopic composition (delta18О, deltaδD) of relict ice wedges is the lightest and amounts –23‰ and –185‰, correspondingly. The isotopic composition of structured ice from sandy loam above ice wedges is –15,7‰, –133‰; of small ice wedge in a peat and sand is –15,3‰, –117,9‰, accordingly. Interpretation of the ice wedge isotope composition has shown that mean winter temperatures during cold stages of Holocene optimum were on 2-3оС lower than today, in warm stages they were close to modern. Total winter temperatures during the coldest stages of Holocene optimum were –5100-5700° x days, i.e. on 300-600° x days colder than during extremely severe modern winters. The total summer temperatures varied from 1300 to 1800° x days, i.e. it was a slightly higher and only occasionally fractionally lower than modern.
