New data on the age of the Emine Formation (East Balkan, Bulgaria)

Abstract

The study represents new data about chronostratigraphic range of the Emine flysch Formation in its type section at the Black Sea coast near the “Irakli” touristic resort. In the highest stratigraphic levels, calcareous nannofossils of NP 10 Rhomboaster bramlettei zone have been documented, supporting early Eocene age for the formation. These new finds will shed light on the timing of cessation of the turbiditic sedimentation in East Balkan, as well as on the specific expression of the global event – the Paleocene–Eocene Thermal Maximum (PETM) in deep-water environment.
