ABSTRACT

This paper presents the results of micropaleontological research of foraminiferal fauna and calcareous nannofossils research of the Upper-Eocene sediments in the Delchevo and Strumica basins on the territory of the Serbian-Macedonian massif in the Republic of Macedonia, which are very important in solving the stratigraphy of the sediments.
The studied micropalaeontological material was obtained from 31 samples coming from the upper flysh unit of 2 outcrop sections belonging to sedimentary basins: Delchevo and Strumica basin in the Serbian-Macedonian massif.The biostratigraphic significance of the foraminiferal fauna in the Upper-Eocene sediments is followed by stratigraphic distribution of 21 species of benthic and planktonic foraminiferal fauna, belonging to 18 genera and 15 families.The results of biostratigraphic nannofossil research revealed that the samples contain well preserved specimens of 17 species.Systematic classification of the foraminiferal fauna was done after Loeblich and Tappan (1988).

Keywords: Foraminiferal fauna, nannofossils, biostratigraphy, Upper-Eocene sediments, Republic of Macedonia.
