Abstract

Magnetotelluric measurements from the Sabalan geothermal field in northwestern Iran have provided clear indications of geothermal reservoirs. This study aimed to identify shallow and deeper conductivity anomalies associated with geothermal systems in the Sabalan area. The magnetotelluric method is widely used for exploring subsurface resources, as it is suitable for detecting subsurface anomalies at significant depths. Based on modeling results, thick conductive layer was found near the surface of the Moil Valley area, where two reservoirs are embedded. The main reservoir, located on the west side of Sabalan volcano, extends from the south and southwest of Sabalan peak to the west and Moil valley. The dimensions of this reservoir are almost twice as large as the estimated volume obtained from previous studies. Another smaller reservoir is located to the north of the peak.
