The systematization of the original and published data on the geology and paleogeography of the Late Pliocene and Early Pleistocene of Eastern Europe was carried out due to the lowering of the Quaternary lower boundary to the level of 2.6 million years ago and the inclusion of the Gelasian stage in Quaternary system. It was revealed that at the bound of the Gauss-Matuyama paleomagnetic epochs, the profound landscape and climate changes took place. The rhythmic fluctuations of the climate intensified against the background of the general trend towards cooling and aridization. Subarctic landscapes appeared during the period from 2.6 to 1.8 Ma, which corresponds to the Gelasian stage (the Praetiglian and Tiglian stages of Western Europe or the Paleopleistocene of Eastern Europe). In the Eopleistocene (1.8–0.78 Ma) and Early Neopleistocene (0.78–0.42 Ma), the climate became colder while the structure of natural zonality repeatedly underwent a complex restructuring and gradually approached to the modern one. The presence of glacial deposits was noted in Eastern Europe already in the Paleopleistocene. The traces of at least three independent glaciations were revealed in the Eopleistocene, and four glaciations were suggested for the Early Neopleistocene. Based on the data from stratotype sections, paragenetic relations between heterochronous sediments in glacial and periglacial areas were established and Early Pleistocene paleogeographic events in Eastern and Western Europe were correlated.
