One of the largest interior basins in Turkey, the Tuzgölü Basin related with the Haymana and Kırıkkale Basins, has smooth topography, a stable young sedimentary cover and limited outcrop zones. But the study area bears a complex geology with intensive tectonism and poor seismic data quality beneath the surface. The complexity of the subsurface geology was attempted to be solved and important structural components giving evident anomalies were determined using the gravity and magnetic methods in integration with each other. Most important determination from the gravity anomaly map is the existence of a large and unique basin (named as Tuzgölü Basin in this study) in the south of Tuzgölü, in spite of separate classification as Tuzgölü Basin and Ulukışla Basin in the previous studies. Another evident anomaly is caused by a channel shaped basin named Tersakan Basin that is connecting Tuzgölü and Haymana Basins each other. Kırıkkale Basin, also, is connected to the Haymana Basin. The most important anomaly in the magnetic anomaly map is the Sülüklü-Cihanbeyli-Gölören Anomaly, which is extending through the western margin of Tuzgölü, Tersakan and Haymana Basins in NW to SE direction. Upward continuation up to 4 km with 1 km intervals was applied to gravity and magnetic anomaly maps in order to observe regionality of these anomalies.
