They are correlated with the first part of the early Oligocene, beginning of the late Oligocene, beginning of the Miocene, beginning of the Chokrakian, Karaganian, and Sarmatian during the Middle Miocene, the Upper Sarmatian and Early Pontian during the Late Miocene, the Akchagilian in the Caspian part in the Pliocene. Regressive phases are fixed based on deep river cuts, which allows to value time and amplitude of erosion basis downfalls. The maximal cuts are dated by terminal Eocene, second part of the Solenovian, end of the Maykopian in the Early Miocene, and early Pliocene in the Caspian Basin. Seismic data allows watching the major discontinuities in deposition in result of water level downfalls and tectonic reasons, which are followed as in shalves, as in deepwater depressions. At least three erosional phases ranging from Paleogene to Pontian time: at the terminal Eocene, terminal Maykopian, and at the Sarmatian – Maeotian boundary. Moreover, intra-Pontian erosional surface is clearly identified. The Eastern Paratethys stratigraphic scale stability during more then 100 years is determined by boundaries, which correlate with tectonic and lithologic-facial reorganizations and main water level downfalls and reflect not only paleontological events. Units, which based on faunistic data mainly, often are not well distinct out of stratotypic area and facial zone. We have these problems with units of the Maykopian second part (Upper Oligocene – Lower Miocene), late Chokrakian – Karaganian and Maeotian – Pontian boundaries. , , - , [10, 13]. - . . , - - - . , 2 , , , 100 " 5" 07-05-00795. .
