Biostratigraphic analysis across the Eocene-Oligocene boundary in the southern Hellenic Thrace basin (Lemnos Island, north Aegean Sea)

The time interval of the sedimentation in the southern Hellenic Thrace Basin (Lemnos Island, northeast Aegean Sea) was studied, based on the qualitative analysis of calcareous nannoplankton and quantitative analysis of planktonic foraminifera. The present study offers the first taxonomic analysis of planktonic foraminifera of this age in the Hellenic southern Thrace Basin (Lemnos Island).
