There are currently three stratigraphic schemes (1993, 1995 and 1996) utilized for stratigraphic subdivision of the Neogene deposits of the Kerch Peninsula. These schemes are mainly based on biostratigraphic (mollusks, foraminifers, ostracods) studies. Therefore local stratigraphic subdivisions in these schemes (according to the Stratigraphic Code of Ukraine, 2012) are essentially biostratigraphic subdivisions, namely «beds with fauna». These stratigraphic schemes have one column with the Neogene deposits of the Kerch Peninsula.

The local stratigraphic subdivisions which allocated mainly in the stratotype areas are shown in this column. The different areas of the Kerch Peninsula have different lithological types of the Neogene deposits. But it is not part of these schemes. These facts impedes using these stratigraphic schemes as a basis for developing legends for large-scale and medium-scale geological maps.

A new modernized stratigraphic scheme for the Neogene deposits of the Kerch Peninsula is represented in this study. The scheme is supported by new and previously published data on the distribution of lithological types of the Neogene sediments and their detailed biostratigraphic analysis.

The stratigraphic scheme for the Neogene deposits of the South of Ukraine (1995) includes regional stratigraphic subdivisions – «horizons» that are subordinate to regional stages. Only those horizons that have characterized by specific molluscs assemblages or other paleontological groups are suggested to use in the new scheme. These assemblages should be typical for different facies of coeval deposits in the most structural-facies zones of the Southern Ukraine.

The volume of local stratigraphic subdivisions of previous stratigraphic schemes (1993, 1995, 1996) has been revised; their stratigraphic status and names have been emended. New local stratigraphic subdivisions, namely formations, beds and strata, have been erected based on the similarity of lithology and biostratigraphy between the Neogene deposits of different investigated areas. The age of those local stratigraphic subdivisions has been determined by key species of different fossil groups. These subdivisions have been correlated with the Neogene regional stages of the Eastern Paratethys. Based on the presence of representative fossil assemblages within some local stratigraphic subdivisions, «beds with fauna» have been introduced.

This stratigraphic scheme of the Neogene deposits of the Kerch Peninsula consists of sheet with a graphic image of the scheme, graphic appendix and the text. The sheet demonstrate the spread areas of local stratigraphic subdivisions, their spatial and stratigraphic correlation and names. The «beds with fauna» have been shown for local subdivisions. The comparison of local stratigraphic subdivisions from this scheme with those from the previous schemes (1993, 1995, 1996) is provided in graphic appendix.
