• A Regional Geochronological Study of Late Pleistocene Permafrost

      Kostyukevich, V. V. (Department of Geosciences, The University of Arizona, 1993-01-01)
      The use of radiocarbon dating in geocryological investigations makes it possible to establish a chronology for permafrost-geological development during the Late Pleistocene. Both global and regional time scales for the formation of Late Pleistocene permafrost have been worked out over the past 15-20 years at the Permafrost Institute of the Siberian Branch of the Russian Academy of Sciences. I present here results from study areas of northwestern Siberia and of North, Central and West Yakutia.
    • Radiocarbon Chronology of Paleogeographic Events of the Late Pleistocene and Holocene in Russia

      14C chronology of Late Pleistocene paleogeographical events in the Black Sea-Caspian Sea region shows that the following transgressions partly correlate with each other: Karangat and Khazarian; Neo-Euxinian and Khvalyn; Holocene and Neo-Caspian. The main climatic events were synchronous in intercontinental Siberia. In the far eastern region, the Middle-Wisconsinan transgression is reflected by Chukotka and western Kamchatka terraces and by submerged ancient shorelines in Primorye.
