Notes:
In 1970, the Turkish Petroleum Company carried out a seismic refraction experiment in the Tuz Gölü (Salt Lake) basin of central Turkey. We present our interpretation, using time-term analysis and ray tracing, of data from one of the two lines shot. This confirms the presence of a thick sequence of sedimentary layers varying from about 3 km below the southwestern end of the profile to about 10 km at two points along the line. A P-wave velocity of 4.0–4.2 km s−1 found beneath the low-velocity surface layer indicates that the principal sedimentary layer consists of evaporites. The lowermost layer of the model has a P-wave velocity of 6.15 km s−1 which is consistent with the sedimentary layers being underlain either by Cretaceous metamorphic basement or by lavas of andesitic type.The extensive coverage provided by this data set has enabled the construction of a detailed 2-D model which shows the complex topography of the subsurface layers. We identify two major faults and one minor fault affecting both the basement and overlying layers. The character of these features and the associated layer displacements leads us to speculate that these may be growth faults associated with the Aksaray-Şereflikoçhisar and Karapinar-Cihanbeyli-Haymana hinge structures which have controlled the development of the Tuz Gölü basin.
