BIOSTRATIGRAPHIC ANALYSIS OF SILICEOUS AND CARBONATE MICROFOSSILS (BACILLARIOPHYTA, COCCOLITHOPHORALES, OSTRACODA) OF BOTTOM SEDIMENTS OF THE KERCH-TAMAN SECTOR OF THE BLACK SEA

Abstract
For the first time siliceous (diatoms, silicoflagellates) and carbonate (ostracods, coccolithophorides) microfossils from the upper Pleistocene and Holocene deposits of the northeastern part of the Ukrainian Black Sea sector were studied. Their biostratificationwas carried out (75-th voyage of the scientific research vessel of the National Academy of Sciences of Ukraine «Professor Vodyanitsky», 2013). The complex study of siliceous microalgae, carbonate nanoflora and microfauna (ostracod) allowed to reconstruct the diversity of hydrological conditions of accumulation of bottom sediments in the Late Pleistocene-Holocene. Lithological and facies characteristics of bottom sediments were also taken into account in various areasof the Prykerskiy Shelf and the adjacent part of the continental slope. Characteristics of lithological and biostratigraphic markers, as well as markers of changes in paleogeographic conditions, are given. The biostratigraphic and lithostratigraphic schemes of the Upper Pleistocene and Holocene deposits of the Black Sea are compared. It is of great importance for the stratification and correlation of geological sections of various regions of the Black Sea, including various facies zones. New paleontological and biostratigraphic data were obtained.
