Abstarct: Evaluation of a geothermal system, in primary steps of exploration is mainly baxsed on results of geological, geophysical, geochemical and remote sensing studies. In this thesis, Takht-e-Soleiman and Silvaneh 1:100000 sheets in West Azerbaijan province was investigated for existing geothermal resources. Exploratory laxyers including geology, alterations, faults, aeromagnetic, gravity and satellite images were integrated to obtain potential map. In this study, a new integration technique was used for exploration of potential geothermal areas. Areas under study consisted some petrological units including igneous, mextamorphic, sedimentary and pyroclastic which were classified as a laxyer baxsed on their relation with geothermal resources. In this classification, the highest rating is given to the travertine and young igneous rocks. Other laxyer included argillic, silicic and iron oxide alterations which were obtained using some remote sensing techniques such as false colour composite, band ratio, least square regression and principal component analysis. Faults and fractures of the region obtained from geological maps, satellite image processing and geophysical methods were considered in another laxyer called faults and fractures laxyer. Two other laxyers were anomaly areas identified by Magnetometric and gravimetric methods. Finally exploratory laxyers were integrated using two knowledge baxsed fuzzy logic and overlaying index methods And potential areas according to their priorities away from the hot springs and compliance with maps factor in any way, and six were ranked most important part of the stack of letters A, B, C, D, E and F were identified. Part of the area known as potential areas covering about 15% of the total study area. Finally, the optimal potential maps using the hot springs that fit very well with the potential showed, were validated and approved. Advantage of this method compared to other methods Potentiometric surveys, simultaneous use of multiple data and to minimize the error.
