The Dempster-Shafer (D-S) belief theory, as a knowledge-driven approach for map combination, is used for porphyry copper potential mapping, in an under-explored area, north of Shahr-e-Babak, Iran. The evidential function provides a theoretical basis for uncertainty management in data integration in an exploration project. The results of this approach show that strong support is found in the west-central part of the study area, where porphyry copper deposits are known. Plausibility for the proposition is also high in the west-central parts and coincides with the zone having strong support. The uncertainty is low in the west-central parts where there are more efficient data layers with respect to the proposition. Uncertainty is high in the zones where either there are fewer data layers or the data cannot provide strong support for the proposition or its negation.
