Abstarct: There are several and different data resulted in exploratory studies that cannot be extracted useful information from it without accurate organization for detection of mineral potential. Finding potential is a stepwise process in order to reduce risk and cost. So using a fusion system makes it possible to achieve the above objectives. The aim of this thesis is identifying possible areas of copper mineralization in the Toroud - moaleman area and in detail on Geological map at a scale of 1:100000 of Kalateh-Reshm and moaleman. According to the developed conceptual models, the data laxyers of lithological, geochemical anomalies, faults, dykes, intrusive and alteration were used in this thesis. So that after performing the preprocessing on data laxyers, each laxyer was classified. In the next step pairwise fusion was done on the data laxyers by determining the Evidential Belief Function method (Dempster-Shafer). In this method the limit of lower and upper the evidential function estimated by using the AND and OR fusion operators. At last the limit of upper and lower evidential function estimated for each data laxyers. In the final step, pairwise fusion the data laxyers together was done by using using the AND & OR fusion operators, the belief, disbelief, uncertainty and plausibility functions were calculated. Finally the areas that located on 7 km from East of ChahMossa copper mine, 15 km from west of CheshmeHafez copper mine and on 5 km from west of Kalout copper mine identified by high potential copper mineralization.
