In southwest Turkey, the Oligocene sedimentary sequence is located on the Datca-Kale-Ac1 Gol basin between the Menderes Massif and Lycian nappes. To understand the nature of this basin is important for tectonic models that explain the exhumation of the Menderes massif. In the northeast 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 Datca-Kale main breakaway fault bounding the south eastern margin of the basin is represented by Inceler and Ac1 Gol faults in the study area. The wedge geometry of the sequence thickening towards the Inceler 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 Datca-Kale-Ac1 Gol 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 Datca-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 of Datca-Kale main breakaway fault are also observed in the northwest of the basin as top to the north-northeast.
