Paleoenvironmental interpretation and findings of Pliocene-Pleistocene nannoplankton, planktic foraminifera, trace fossil in the Mut Basin [Mut Havzasi Pliyosen-Pleyistosen nannoplankton, planktik foraminifera, iz fosil bulgulari ve paleoortam yorumu]

In this study, carried out in the Mut Basin, Reticulofenestra pseudoumbilica (Zanklian), Dictyococcites productus (Gelasian), Pseudoemiliana lacunosa (zones), Calcidiscus macintyrei, Helicosphaera sellii and Small Gephyrocapsa (Sub zones) (Gelasian-Kalabrian) nannoplankton zones with Globorotalia puncticulata (Zanklian-Piasenzian), Globorotalia inflata (zones) (Piasenzian-Gelasian) and Globigerina calida calida (Sub Zone) (Kalabrian) planktic foraminiferal zones were recognized in 72 samples collected from 3 measured stratigraphic sections at the upper levels of marginal deposits of the Köselerli formation. Based on these biozones, it is found that, age of the Köselerli formation has been extending to early Pleistocene (Kalabrian) at its marginal deposits. In the previous studies, the age of basin deposits of Köselerli formation has been determined as late Burdigalian-Langhian.
