Öz

The presence of the evaporate salt zone in Ankara-Polatlı region has been determined by the drillings. It is thought to be the largest reserve in Türkiye. The seismic reflection method was used to determine the top-bottom levels of the region; its depth; its thickness and extent boundaries; the horst-graben structures; base depth and tectonic movements affecting the study area. Data were collected on three seismic lines. The near-surface tomographic velocity sections were compatible with the top-of-the-zone depth observed in the drillings. As a result of the study, the depth and thickness of the top-bottom of the zone were determined along the lines. Within the scope of the study, a combined interpretation was made on the lines by using gravity and seismic data. The extent of the ore zone was determined only in the E-W direction section, but not in the north-south direction lines since they are outside the license area and the seismic lines. The closest point of the evaporate zone to the surface is approximately 150 m, the deepest point is approximately 310 m, the average thickness is approximately 100 m and the maximum thickness is 185 m.
