摘要

Geothermal energy has long been used for various purposes. Geothermal energy was used for bath and health care since ancient times. With the increase in the population, it is being used today for industrial and energy production. This paper examines the geothermal structure of Northern Ankara-NAF (Northern Anatolian Fault Zone) regions to reveal its tectonic features, and the relationships of the region with earthquakes. The 3D geological features of the area are investigated using the resistivity data and tectonic and the quake values. The resistivity data obtained by MTA (Mineral Research and Exploration of Turkey) are reached by geothermal measurements in the area in 1999. In Kizilcahamam town of Ankara Province, geothermal exploration was performed using geoelectrical methods. During the study, electrode measurement scheme was planned according to the Schlumberger expansion. AB/2 spacing is between 1900 m. and 2000 m. Data obtained from geoelectrical methods were processed to delineate the subsurface structure. Also, lithological components were determined and the previously known fault structure was shown. Since the 3D works have been more feasible recently, the received results are transferred into the 3D imaging platform taking advantage of 2D electrical resistivity maps. The low resistivity values obtained in 3D imaging are gathered that the temperature values of the area are high. On the other hand, as the pull-apart between NAF and Kirikkale fault trending NE-SW of the region is in form of basin, the study area is observed to own opening tectonics. Thus, when the seismic activity is considered, it reveals important findings about the presence of geothermal fields in the local.
