| Abstract | A magnetotelluric line named as AG crossing Isparta Angle tectonic zone between Afyon and Antalya was taken to define geoelectrical structure. Two-dimensional (2-D) modeling of this profile was used to derive the resistivity structure and investigate its implication on possible geothermal activity within the crust. The magnetotelluric results in the view of the 2-D geoelectric structures, with true resistivity values, obtained from transverse electric (TE), transverse magnetic (TM) data and joint TE-TM inversion was interpreted. The 2-D models of geoelectric structures obtained from these inversions were clearly displayed the existence of an electrically conductive (<50 m) zone (ZONE-1) beneath Sandikli Graben (around Afyon) where is the popularly known as a geothermal region. Another conductive zone (ZONE-2 with ~5-10 m) was defined beneath Dinar Graben where is seismically active. The sharp decreasing of the resistivity to very low values probably suggests that both zones ZONE-1 and ZONE-2 are highly permeable and saturated with geothermal fluids. |
