Gilan-e Gharb region has been located in the west of Iran and it has special features in terms of geology. Remote sensing data (satellite images), geology, tectonics and mineral data sets of the region were used to prepare an innovative integrated method for the exploration of Gilsonite mineral. Effective criteria and sub-criteria in the exploration of this mineral were identified and evaluated according to the available exploration data. Afterwards, these criteria were weighted using Fuzzy Analytical Hierarchical Process (FAHP). Accordingly, the ideal positive and negative solutions were ranked using a Fuzzy TOPSIS method to prepare a mineral potential mapping (MPM) of Gilsonite in Gilan-e Gharb region. The product of this paper is a potential map used for optimal identification in the early stages of exploration of Gilsonite mineralization that reduces the time, cost, and risk of exploration. Finally, the field’s visit and investigation has been accomplished for the regions with a high potential of Gilsonite mineralization to evaluate the proposed method. The results showed that 82% of the identified points had proper adjustment to the MPM. This high adaptation showed that the proposed method has good performance in Gilsonite exploration.
