Abstract: 

A comprehensive lithological and biostratigraphic investigation into diatoms and chrysophycean stomatocysts was conducted on two boreholes from the central zone of the Kostenets Neogene Basin. The diatom flora consists of 105 species, varieties, and forms. The results of these different analyses presented herein indicate three successive stages in the palaeoenvironmental development of the Kostenets Basin, at the end of the Miocene and the beginning of the Pliocene.

Keywords: 

diatoms, chrysophycean stomatocysts, sedimentology, palaeoecology, Kostenets Neogene Basin, Bulgaria
