Eocene-Oligocene Succession At Kıyıköy (Midye) On The Black Sea Coast In Thrace, Aral I. Okay, Michael D. Simmons, Ercan Özcan, Stephen Starkie, Michael D. Bidgood, Andrew R.C. Kylander-Clark
Eocene-Oligocene Succession At Kıyıköy (Midye) On The Black Sea Coast In Thrace, Aral I. Okay, Michael D. Simmons, Ercan Özcan, Stephen Starkie, Michael D. Bidgood, Andrew R.C. Kylander-Clark
Turkish Journal of Earth Sciences
A belt of Upper Eocene-Lower Oligocene marine sedimentary rocks extends from Kıyıköy on the Black Sea coast to Pınarhisar in the Thrace Basin, suggesting a marine connection between the Black Sea and the Thrace Basin during this period. The Cenozoic succession of this marine corridor was studied in the vicinity of Kıyıköy along two measured stratigraphic sections. The sequence lies unconformably over metamorphic basement rocks and consists of ~75 m of bioclastic limestone and sandstone of the Soğucak Formation, overlain by ~40 m of limestone, marl, mudstone, sandstone, and acidic tuff, which are assigned to the newly defined Servez Formation. …
Biostratigraphy And Paleoenvironments Of The Oligocene Succession(İhsaniye Formation) At Karaburun (Nw Turkey), Michael D. Simmons, Michael D. Bidgood, Paul G. Connell, Stjepan Coric, Aral I. Okay, David Shaw, Emilia Tulan, Jan Mayer, Gabor C. Tari
Biostratigraphy And Paleoenvironments Of The Oligocene Succession(İhsaniye Formation) At Karaburun (Nw Turkey), Michael D. Simmons, Michael D. Bidgood, Paul G. Connell, Stjepan Coric, Aral I. Okay, David Shaw, Emilia Tulan, Jan Mayer, Gabor C. Tari
Turkish Journal of Earth Sciences
The biostratigraphy and paleoenvironments of the İhsaniye Formation exposed at Karaburun in northwest Turkey is described based upon the study of abundant and well-preserved foraminifera, calcareous nannofossils and palynomorphs. The studied succession is Early Oligocene in age, with calcareous nannofossil zones upper NP21 (Subzone CNO1) to lower NP23 (Subzone CNO3) and planktonic foraminifera zones O1 (~P18) and O2 (~P19) represented, and palynological assemblages suggestive of zones D13 to D14a. Based on these new data, a revised interpretation of the stratigraphic succession is presented. Deposition was controlled by a now inverted normal fault, with deposition of older stratigraphy (upper NP21 to …

Late Eocene To Early Oligocene Palynostratigraphy Of The Western Black Sea, Easternparatethys, Recep Hayretti̇n Sancay, Zühtü Bati
Turkish Journal of Earth Sciences
The Eastern Thrace and Western Black Sea basins provide unique perspectives on the palaeogeographic reconstructions of the Paratethys. Although very thick and extensive Oligocene outcrops and well sections exist in the Thrace Basin, only a few comparable sections are available in the Black Sea onshore areas. In this study, five measured stratigraphic sections of Eocene to Oligocene age from the margins of the Western Black Sea were studied and palynomorph assemblages were identified quantitatively. Index dinoflagellate cyst events and a palynological biozonation as established in the Mediterranean were applied successfully. Priabonian units contain the Aal biozone, whereas Rupelian successions were …
Microfossil Assemblages (Diatoms, Calcareous Nannofossils, And Silicoflagellates),Paleoenvironment, And Hydrocarbon Source Rock Potential Of The Oligocene Ruslarformation At Karadere, Bulgaria, Emilia Tulan, Reinhard F. Sachsenhofer, Jakub Witkovski, Gabor Tari, Stjepan Coric, Achim Bechtel
Microfossil Assemblages (Diatoms, Calcareous Nannofossils, And Silicoflagellates),Paleoenvironment, And Hydrocarbon Source Rock Potential Of The Oligocene Ruslarformation At Karadere, Bulgaria, Emilia Tulan, Reinhard F. Sachsenhofer, Jakub Witkovski, Gabor Tari, Stjepan Coric, Achim Bechtel
Turkish Journal of Earth Sciences
The Oligocene Ruslar Formation, an equivalent of the Maykop Suite, is a potential hydrocarbon source rock in the western Black Sea Basin. In contrast to the offshore areas, the depositional environment and hydrocarbon source rock potential of onshore Bulgaria sediments are largely unknown. Hence, a 14-m-thick section of the Ruslar Formation, exposed near Karadere (Black Cape) along the Black Sea coast, provides an excellent opportunity to study the upper part of the Ruslar Formation. Here, laminated diatomrich mudstones with frequent thin sandstone beds and a prominent concretion horizon are exposed. Furthermore, the fossil diatom assemblages provide a key component to …
The Stratigraphy Of The Oligocene-Lower Miocene Deposits Of Southern Ukraine, Yuliia V. Vernyhorova, Tamara S. Ryabokon
The Stratigraphy Of The Oligocene-Lower Miocene Deposits Of Southern Ukraine, Yuliia V. Vernyhorova, Tamara S. Ryabokon
Turkish Journal of Earth Sciences
Lithostratigraphic units (formation, strata, and beds) and regional stages of the Oligocene-lower Miocene succession of southern Ukraine are described based on the results of comprehensive lithological and paleontological data analysis. The historical perspective on the stratigraphical investigations of the Maikop Group in the Crimean and Kerch Peninsulas and their equivalents in the broader Peri-Black Sea Region were also integrated in this overview. Moreover, a correlation was established between the locally defined regional stages and specific stratigraphic horizons of southern Ukraine, the global Oligocene and Miocene stages (defined by the International Stratigraphic Chart), and the stages of the Eastern Paratethys. The …
