- Аннотация: Terrestrial and marine climate-chronostratigraphic records, spanning the last 900 ka, were obtained using data from glacial, periglacial, and palaeoshelf zones of Northern Eurasia. Climate and vegetation evolution during this period is characterized by pollen data from a series of spaced-apart reference long sequences on the East European Plain. The temporal positions of the identified palaeoenvironmental events were determined on the basis of electron spin resonance (ESR) analysis of subfossil mollusc shells collected from marine, freshwater, and terrestrial habitats. The analysis of the obtained data enabled to revise the existing views of the three principal regularities in the evolution of vegetation and climate (directionality, rhythmics, and local features): to establish new trends and regional peculiarities in the evolution of Neopleistocene floras, to specify the number of interglacial and glacial epochs within the studied time interval and others (Bolikhovskaya 2007). In addition, one more regularity in the evolution of the Neopleistocene climate and vegetation was established by authors – approximately ca 450 ka cyclicity. The presence of two long-term environmental cycles over the last 900 ka was established. Each of them lasted ca 450 ka, covering four interglacial and four glacial stages. Each of the interglacial or glacial stages of the younger cycle (MIS 10 to MIS 1) had its palaeoenvironmental counterpart in the preceding cycle (MIS 20 to MIS 11). On the basis of the established regularities, it is assumed that the duration and the main palaeoenvironmental features of the Holocene (MIS 1) will, approximately, be the same as those of its palaeoenvironmental counterpart ― the Likhvin interglacial (MIS 11).
