FORAMINIFERS DEVELOPMENT AND PALEOGEOGRAPHY OF SEAS OF THE NORTHERN OUTSKIRTS OF DONBAS IN THE CENOMANIAN – CОNIACIAN TIMES

Abstract

The development and changes in the species and generic composition of the Cenomanian–Coniacian foraminifers from the sediments of the Northern outskirts of Donbas are traced. The paleogeographic features of the development of the sea basins of the Cenomanian, Turonian and Coniacian times of this territory based on foraminifers are characterized. Paleogeographic reconstructions of these basins are detailed based on foraminiferal studies. A direct influence of the abiotic conditions of marine paleobasins on foraminiferal associations was found.
