• Geochronology of the Holocene of the Belorussian Polessie

      Matveev, A. V.; Krutous, E. A.; Zernitskaya, V. P. (Department of Geosciences, The University of Arizona, 1993-01-01)
      We distinguished major stages of the last glaciation (Bulling, Older Dryas, Allerod, Younger Dryas) and the Holocene by radiocarbon dating and paleobotanical analyses. Our paleobotanical investigation of peatlands is well correlated with independent 14C data. We establish that the Atlantic and Subboreal stages of the Holocene have three divisions, and that the Subatlantic has two.

    • Geochronology of the Pleistocene and Holocene in the Fore-Urals

      Latypova, E. K.; Yakheemovich, B. L. (Department of Geosciences, The University of Arizona, 1993-01-01)
      The paper presents the results for the 14C dating obtained recently in the Laboratory of the Institute of Geology, Ufa Science Centre, Russian Academy of Science, on the basis of megafaunal bones, peats, wood and mollusk shells. Dates are reported in stratigraphic sequence from the Late Wurmian to the Holocene.
    • Possibilities for Detailed Dating of Peat Bog Deposits

      Punning, Jaan-Mati; Ilomets, Mati; Koff, Tiiu (Department of Geosciences, The University of Arizona, 1993-01-01)
      Geochemical and palynological data as well as radiocarbon dating were used to study the peat bog deposits in Niinsarre bog, northeast Estonia. The aim of this study was to establish criteria for determining a detailed chronology, which is important, for example, in studying paleoevents and historical monitoring. In some cases, we can use cumulative pollen data, as well as cumulative chemical and peat bulk density data.
    • Radiocarbon Dating and Tephrochronology in Kamchatka

      Braitseva, O. A.; Sulerzhitsky, L. D.; Litasova, S. N.; Melekestsev, I. V.; Ponomareva, V. V. (Department of Geosciences, The University of Arizona, 1993-01-01)
      We discuss results of 14C dates obtained from areas of young volcanoes in Kamchatka. We apply these dates to reconstructing regional volcanic activity during the Holocene.
    • The Reliability of Radiocarbon Dating Buried Soils

      Orlova, L. A.; Panychev, V. A. (Department of Geosciences, The University of Arizona, 1993-01-01)
      Variable 14C ages of paleosol organic matter (OM) cause difficulties in interpreting 14C data. We attempt to determine the reliability of OM 14C dates by examining different carbon-containing materials from soil horizons and paleosol fractions.
