Tectonic and eustatic history of the East European Plate strongly influenced the accumulation of Palaeogene sediments. Due to these factors, lower part of Palaeogene deposits is distributed in an elongated area with an axis stretches N-S, and the upper strata in an area that extends E-W. Micropalaeontological investigation of diversified Palaeogene lithofacies allowed us to subdivide and correlate Palaeocene and middle Eocene sediments of the East European (Russian) Plate and to propose the picture of its evolution during the Palaeocene-middle Eocene time.
