The Catallar Basin is one of the Miocene basins located in the southern part of the Bey Daglan Massif (SW Turkey). This basin has been reinvestigated and new stratigraphic and sedimentological data are now presented. The Catallar Basin lies in paraconformity on the Bey Daglan carbonate platform of Late Cretaceous to Palaeogene age. It consists of an impersistent, shallow-marine carbonate base (Karabayir formation, Late Oligocene to Early Burdigalian) followed by an onlapping detrital sequence including the Akcay and Bagbeleni formations (Langhian to Serravallian). The Akcay formation mainly contains turbidites in which several debris-flows and olistostromes are intercalated. The lowest debris flows derive from the local carbonate platforms of Cretaceous and Palaeogene age. Higher, the debris flows and olistostromes contain large carbonate blocks deriving from nearby sources (Bey Daglan platform carbonates), whereas the accompanying pebbles originate from the allochthonous ophiolitic units located farther to the north (Lycian Nappes) or to the east (Antalya Nappes). The origin of these ophiolitic detritus is a matter of debate. The new data obtained in this study favour a northern origin. (C) 2008 Elsevier Ltd. All rights reserved.
