Özet

Copyright © Congress of Balkan Geophysical Society, BGS 2019. All rights reserved.A magnetotelluric survey has been conducted in the Cappadocia region of central Turkey in order to find new geothermal resources. The survey area has formerly been postulated as the location of a buried caldera that was one of the main eruptive centres of Cappadocian Volcanic Province. Three-dimensional non-linear conjugate gradient inversion of magnetotelluric data by using the full impedance tensor helps to delineate the subsurface resistivity distribution. The derived resistivity model reveals the possibility of a buried caldera. The low resistivity anomalies are interpreted as the clay alteration zones caused by hydrothermal activities.
