The high-temperature geothermal reservoirs associated with detachment fault in the study area have formed along the normal faults nearly in E-W orientation and in intensely fractured rocks in a structurally complex manner associated with transfer faults approximately in N-S orientation. Generally, it has been determined that the reservoirs are closely located to strike-slip faults intersecting, overlapping, and/or terminated with Quaternary transfer faults.

Fault and layer planes were measured at the observation points to obtain information about the faulting properties, fault geometry, faulting environments that will carry the geothermal fluid up, and bring out the geothermal potential of the area. Within the scope of field studies, alteration zones were mapped in the study area. The alterations areas were generally observed at the intersection of the strike-slip faults that tear high-angle normal faults in the north, which intersect the stepping faults. The intersection zones of the bounding detachment faults which limit the study area from the southwest with the NW-SE trending high-angle normal faults with southern-to-north steps and the NE-SW trending transfer faults in the subsurface were identified as the areas with high potential for the existence of a high-temperature geothermal field.

Within the study’s scope, fault-fracture and layer planes are measured at 110 stop points and plotted to the rose diagram and Wulff network. Thus, geological sequence, fault orientations, types and geometries, intersection areas, and lateral and vertical displacements of the faults, tensional-compressional areas, main compression directions, and rotation regions are determined. The geological and morphotectonic maps of the region are prepared. The formation mechanisms of the hanging rhyolite and dacite caps, along with the large-sized tears in the middle and west of the graben, were also explained using those maps. The main tectonic structures and the faulting characteristics of the Tuzla, Deliömer, Gümüldür, and Değirmendere Fault Zones that boundary these structures, and the relations between the geological setting and the geothermal system are detailed. In the light of the new field data obtained, a new geological model of the graben has been constructed, and the geothermal potential has been reevaluated.
