We have used magnetotelluric equipment to investigate the possibility of an existing geothermal reservoir in an area close to the city of Khoy located in the north-west of Iran. Data of 60 stations were collected in this area of about 30 square kilometers. To perform the data processing procedure, we used a computer program called PROCMT, and for in interpretation of available data a computer program called GEOTOOLS was used.
We recognized an east- west trend for the observed anomalies in this area. In two dimensional modeling of north- south profiles using rapid relaxation inversion (RRI) on TE and TM, low resistivity anomalies were found at a depth of 500 to 2000 meters.
