ABSTRACT: 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.
