Summary:
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.
