Stratigraphy of Karaburun Peninsula

In the Karaburun peninsula, a tectonic bell with a thick Mesozoic succession is located bordering the Izmir-Ankara zone on its western side. In the stratigraphic column of the Karaburun belt, the oldest unit is the Lower and Middle Carboniferous Alandere formation consisting dominantly of fossiliferous limestones. Lower Triassic rocks rest directly above this unit and Upper Carboniferous and Permian sections are missing. The Lower Triassic is represented by rock units showing facies changes in short distances along vertical and horizontal directions. In this part of the section, the Karareis and Gerence formations are differentiated which are collectively named as the Denizgiren group. The Karareis formation is composed of intercalations of sandstones, bedded-black cherts, pelagic limestones and mafic volcanics, whereas the Gerence formation composed dominantly of ammonitic red limestones, thinly-bedded gray limestones, and cherty limestones. The Karareis and Gerence formations grade laterally into each other and range in age from Scythian to Late Anisian. The Camiboğazı formation resting with a gradational contact on each of these units consists of massive limestones with reefal facies in places and yields an age of Ladinian-Camian. The Güvercinlik formation lies conformably above the Camiboğazı formation and consists of algal stromatolites, megalodon-bearing limestones, and quartzitic sandstone intervals. This unit ranges in age from Norian-Rheatian. The Nohutalan formation which is dominantly represented by thick-bedded neritic limestones overlies the Güvercinlik formation gradationally and yields an age ranging from Liassic to Albian. This unit appears to be lithologically continuous in the field without any indications of a break in the stratigraphic or structural record, however, the Dogger age has not been determined which may probably indicate a presence of a hiatus. Above this Mesozoic comprehensive succession with an age spanning from Early Triassic to Early Cretaceous, The Balıklıova formation of Campanian-Maastrichtian age rests unconformably, which consists of carbonate rocks and sandstones of flysch facies. The Karaburun belt with the stratigraphy outlined above is surrounded from all sides by a blocky unit which is called the Bomova melange. This blocky unit with highly sheared flysch matrix was formed in the Izmir-Ankara zone during a Maastrichtian-Danian interval. The boundary relations between the Karaburun belt and the Bomova melange indicate that the Karaburun platform was transported tectonically as a nap into the İzmir-Ankara zone during its opening. In this study, we have also found that the stratigraphy of the Karaburun belt is completely different from that of the so-called Sakarya continent, and they cannot be correlated with each other as suggested by the earlier workers.
