Exploration activities mostly provide geoscientist with the huge volume of information such as geological, geochemical, geophysical, remote sensing data. Traditional methods usually deal with specific data separately; however, nowadays integration methods enable scientists to carry out analyses on the whole data simultaneously. It is obvious that the results obtained by methods in which all data and their relation are involved, are more rigorous and reliable. The integration methods mainly have been applied in regional-scale studies to delineate potentially mineralized areas and centralize next exploring activities, and they are rarely used to in detailed-scale studies. In this research, surficial exploratory data of the Tafresh 1:100,000 sheet located in Markazi province and north-western of Qom province were integrated to delineate porphyry copper mineralized areas using Fuzzy Logic method. These data consist of lithology map, airborne geomagnetic map (reduced to the pole of magnetic data), geochemical map of stream sediment data, structural map and alteration map. After producing the base maps and required data layers for integration step, weighting stage of layers and their classes was carried out concerning their importance. Then information were fuzzed and modeled for porphyry copper prospecting and resultantly areas for further exploration activities were highlighted.
