BIOSTRATIGRAPHY OF PALEOGENE THE SOUTHERN UKRAINE BY SMALL BENTHIC FORAMINIFERA: RETROSPECTIVE VIEW

The article deals with history of small benthic foraminifera biostratigraphy of Paleogene deposits the southern Ukraine. The significance of O.K. Kaptarenko-Chernousova, A.M. Voloshina, M.V. Yartseva, Ye.Ya. Kraeva, A.P. Pechenkina, N.G. Savenko and I.D. Konenkova’s works on study foraminifera is shown. Due to their investigarions the sequence and space-time relationships of Paleogene small benthic foraminifera assemblages have been determined in the southern Ukraine. Comparison foraminifera assemblages of Paleogene the southern Ukraine with intergerional benthic foraminifera zones of the Crimea-Caucasus Region is given. The article provides full references to previous literature on Paleogene foraminiferal biostratigraphy of the northern Peri-Black Sea Region and the southern slope of Ukrainian Shield. Up to the beginning the seventies years of the last century the researchers had distinguished and had described foraminifera assemblages characterizing Series and regional units of Paleogene the southern Ukraine. Taxonomic composition of benthic foraminifera assemblages was defined. Their spreading in Paleogene section of the northern Peri-Black Sea Region, the southern slope of Ukrainian Shield and adjacent part the Azov Crystalline Massif was studied. For some foraminifera assemblages the regional significance has been proved. Other assemblages are important for characterizing and dating suites, members, stratum and beds of the local stratigraphic schemes. Foraminifera associations of relatively deep-water depositional environments of the south of the northern Peri-Black Sea Region include species of zonal assemblages of interregional benthic foraminifers zones the Crimea-Caucasus Region. The most of distinguished benthic foraminifera assemblages are characteristic for shallow- and marginal-marine sediments of Paleogene basin in the northern Peri-Black Sea Region and its peripheral facies within depressions the southern slope of Ukrainian Shield. The space-time relations of benthic foraminifera assemblages are defined for Paleogene regional stages of the southern Ukraine section.
