Research Article Keywords: ABSTRACT Datça- Kale- Acı Göl In southwest Turkey, the Oligocene sedimentary sequence is located on the Datça-Kale-Acı Göl basin, Datça- Kale main breakaway fault, basin between the Menderes Massif and Lycian nappes. To understand the nature of this basin is Extension, Oligocene, important for tectonic models that explain the exhumation of the Menderes massif. In the northeast Tectono-sedimentary. extension of this basin, the sedimentary sequence is interpreted as alluvial fan, fan-delta, beach, marine input, inner shelf carbonates and offshore deposits. The Oligocene Datça-Kale main breakaway fault bounding the south eastern margin of the basin is represented by İnceler and Acı Göl faults in the study area. The wedge geometry of the sequence thickening towards the İnceler normal fault is an evidence of syn-tectonic deposition. The northwest margin of the basin is controlled by two en-echelon faults. The sedimentary sequence has a wedge geometry thickening towards the normal fault and at the same time its upper layers overlap the fault. As a result, the northeast extension of the Datça-Kale-Acı Göl Oligocene basin is an elongated fjord like depositional area containing the shallow marine environments controlled by normal faults located in its southeast and northwest margins. It was demonstrated that the southeast basin margin limited by the Datça- Kale main breakaway fault performed dominant tectonic control. The similar kinematic indicators that is used for the model explaining the exhumation of the Menderes massif by the upward bending Received Date: 02.05.2018 of Datça-Kale main breakaway fault are also observed in the northwest of the basin as top to the Accepted Date: 22.10.2018 north-northeast. 1. Introduction Datça-Kale main breakaway fault, which is associated with the exhumation as an asymmetric core complex The Datça-Kale-Acı Göl Oligocene basin is of the Menderes massif (Seyitoğlu et al., 2004). located between the Menderes massif and the Lycian nappes in southwestern Anatolia and has a northeast- The outcrops belonging to Oligocene sedimentary southwest extension (Figure 1). The outcrops of units were mapped in the north of the Gökova Bay Oligocene basin units in the region can be traced from (Gürer and Yılmaz, 2002). The Datça fault located in the Gökova Gulf to Kale and from the northeast of the south of the bay in the submarine seismic reflection Denizli to Dinar area, and have been studied in the studies carried out in the Gulf of Gökova, is seen literature giving different basin names (eg. Lycian in listric normal fault geometry dipping northward molasse basin, Kale basin, Kale-Tavas basin, Çardak- (Kurt et al., 1999).

It was interpreted that Datça-Kale-Acı Göl perpendicular to the Datça fault reveal the presence basin was developed on the hanging wall block of the of a sedimentary sequence which is 2500 m thick and Citation info: Elmas, G., Seyitoğlu, G.
