The correlation of the Neogene sediments of Paratethys is conducted and confirmed on the basis of new data obtained from an integrated approach using bio-, litho-, cyclo-, and magneto-stratigraphic methods. Detailed analysis of planktonic microfossils distribution (foraminifera, nannofossils and dinocysts) in the Neogene deposits of the Central and Eastern Paratethys, as well as data obtained from wells drilled within the Azov-Black Seas’ aquatories enabled to justify the boundaries of the Neogene stratigraphic units of different ranks and establish 10 associations of marine plankton (correlation levels). In addition to biostratigraphy the seismic-, cyclo-, magneto-stratigraphic, tectonic, sedimentological and morphostructural criterias were applied. The influence of volcanic activity, in particular the mud volcanoes onto stratigraphic units is analyzed. As a result, the boundaries and volumes of regional and local (including the diachronous) Neogene units of the Central and Eastern Paratethys within Ukraine territory were specified. The correlation with coeval units of Neogene from Romania, Poland, Slovakia, Bulgaria, Southern Russia, Georgia, Azerbaijan, as well as with the International stratigraphic chart is given. The interregional stratigraphic scheme of Neogene sediments of the Central and Eastern Paratethys of Ukraine is also presented.
