New evidence for the record of the Cenomanian–Turonian oceanic anoxic event (OAE2) in the Pamphylian basin (Akdoğan Section, Antalya Nappes, SW Turkey): Comparison with surrounding basinal settings

The organic-rich black shales in the Akdoğan section (Antalya Nappes, SW Turkey) are the first reported evidence of the global Cenomanian-Turonian Oceanic Anoxic Event (OAE2) in the "Isparta Angle" region. Their age and organic geochemical characteristics are similar to those of other OAE2 intervals in the Pamphylian basin and neighbouring basins of the Tethyan realm. A short description of the whole Akdoğan sequence allows us to compare it with other similar sequences in the surrounding areas and to discuss the local versus global controlling factors on the record of OAE in the Pamphylian basin. ► The OAE2 anoxic event has been described in the Akdoğan section (Antalya Nappes, SW Turkey). ► The study provides information about organic matter and radiolarian content of organic carbon-rich sediments. ► The study discusses the paleogeographic conditions which led to organic carbon-rich sediment deposition. ► The study finally compares organic carbon-rich sediment occurrences with other deep settings from nearby basins.
