Abstarct: Geological Map 1/100000 of Hashtrood include an area in eastern Azerbaijan province and western Alborz-Azerbaijan zone. The purpose of this study, the combination of the different laxyers of information in a GIS environment to determine suitable areas for exploration for copper and associated elements. To understand the problem has been used of satellite data, geochemistry, geophysics and geology of the area. In the chapter of Remote Sensing sensors of ASTER and ETM + images are examined and processed. For processing the images from color mixing techniques, band ratio, principal component analysis and least squares regression was used. The resulting images, the alteration was found. In geochemistry, stream sediment geochemistry data is used and a map of the anomalies of copper and associated elements are obtained. In geophysics, airborne magnetic data were used in the maps of various filters, including filters applied to pole, surface process, extending the upward vertical derivative, angle of inclination and horizontal differentiation of the angle of inclination, place the mass of intrusive and alteration in the region were identified. Final data obtained from geological laxyers of processing, remote sensing, geochemistry and geophysics each laxyer of information obtained in application environment GIS, using fuzzy logic and the final result to determine the optimal together to locate potential copper was obtained. The host rock of copper in the area include Middle Eocene intrusive and volcanic rocks such as granite and granodiorite, diorite, andesite, Trachyandesite, basalt and monzonite.
