Geological Structure and Geothermal Potential of the Southeastern Alaşehir, Gediz Graben (Western Anatolia, Turkey)

Abstract
In this study, the observations at different locations were made to explain the structural features of the region where the study area is located and to reveal its faulting type, geometric properties, and faulting mechanism in detail. 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 b ring 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.References
