Journal Article: Deep Resistivity Structure Of The Dikili-Bergama Region, West Anatolia, Revealed By Two-Dimensional Inversion Of Vertical Electrical Sounding Data

Abstract
Within the framework of the National Marine Geological and Geophysical Program, we re-examined deep vertical electrical sounding (VES) data. The data, measured in 1968 by the General Directorate of Mineral Research and Exploration (MTA) of Turkey with the aim of exploring the deep resistivity structure of the Dikili-Bergama region, focus on the geothermal potential. The geoelectrical resistivity survey was conducted using a Schlumberger array with a maximum electrode half-spacing of 4.5 km. The two-dimensional (2D) inversion was utilized to interpret the VES data that were collected along 15- to 30-km profiles. The 2D resistivity-depth cross-sections obtained show very low resistivity values near the Dikili and Kaynarca hot springs. The 2D inversion results also indicate the presence of fault zones striking nearly N-S and E-W, and fault-bounded graben-horst structures that show promising potential for geothermal field resources. The 2D gravity model, which is in good agreement with the density variation of the region, supports the resistivity structure revealed by 2D inversion. The lithology information obtained from the borehole near Kaynarca also confirms the results of the resistivity interpretation and the density model.
