| 英文摘要 | The paper summarizes the new analytical studies of the Quaternary deposits of West Taimyr and presents the results of spore-pollen, fauna, grain-size and mineralogical, geochemical, isotopic and other analyses. Latest dating for the supporting geocryological transects enable us to refine the stratigraphy and palaeogeographical reconstruction of depositional environments and the freezing sediments late Pleistocene-Holocene in West Taymyr. The long marine sedimentation in the late Kargino time (MIS 3) gives way to continental conditions. Marine sediments were frozen syngenetically and epigenetically with the formation of cryostructure and ground ice. Polygonal vein ice formed in the late Pleistocene (MIS 2) and is characterized by values of the stable isotopes of oxygen (δ18O) -26 ‰...-23 ‰ and hydrogen (δD) -198 ‰...-172 ‰, and predominance of HCO -3 - And Ca2+ ions in the ice. Holocene (MIS 1) polygonal vein ice is characterized by values of the oxygen (δ18O) -20 ‰...-17 ‰ and hydrogen (δD) -160 ‰...-126 ‰ and the prevalence of Cl-and Na+ ions in the ice. |
