Late Pleistocene Geochronology of European RussiaI constructed a Late Pleistocene geochronological scale for European Russia employing 14C dating and paleobotanical studies of several reference sections.
Radiocarbon Chronology of Paleogeographic Events of the Late Pleistocene and Holocene in Russia14C 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.
Reconstruction of Caspian Sea-Level Fluctuations: Radiocarbon Dating Coastal and Bottom DepositsOwing to the large basin area of the Caspian Sea, fluctuations in its level reflect climatic changes in the northern hemisphere. To reconstruct these fluctuations, I collected mollusk shells, plant debris, carbonates and organic matter samples for 14C dating from deposits of ancient salt marshes, depressions and bars formed during significant sea-level decline. I studied the impact of eolian sedimentation via parallel dating of carbonates and other materials. The data demonstrate that sea level rises during periods of cooling and falls during warming periods; this is true for both long-term (2-2.5 ka) and short-term climatic changes.
