Abstarct: Mineral potential mapping using remote sensing, aerial geophysical, geochemical and geological data of stream sediments was conducted to identify mextal mineralization in the two sheets of 100,000 Kodegan and Basiran in eastern Iran in two stages: the first stage includes the extraction of exploratory parameters related to mextal mineralization and the second stage includes the integration of data using the decision-making method of the fuzzy hierarchical process. Hydrothermal alterations and iron oxides in the region were mapped using optimal index coefficient, band ratio and least squares fitted in remote sensing data. Existence of intrusive bodies are effective parameters in identifying copper and gold mextal mineralization zones, which were applied using gradient tensor method on aerial magnetism data. To determine the threshold concentration and location of mineralization anomalies, K-means clustering algorithm, vertical geochemical zoning index, multifractal analysis of concentration-area and singularity were implemented on geochemical data. Different methods were used to analyze and interpret Landsat 7 remote sensing data, aerborne magnetism, geology and geochemical samples of stream sediments. The studied area includes some porphyry copper-gold occurrences, indices and mines. This research was carried out in the eastern area of the Lut block and in Basiran and Kodegan sheets using 1430 stream sediment samples, including 586 samples in the Basiran sheet and 844 samples in the Kodegan sheet with the combined methods of geochemical zoning index and singularity. In the final output of the obtained hierarchical integration, the area of 490 square kilometers out of 5200 square kilometers of the investigated area was introduced as promising areas. 22 known mineral indices related to copper mineralization were used to validate the processes, of which 17 indices, equivalent to 77% of them, were found in the areas identified in this study. Therefore, the exploration model of porphyry gold copper deposits in the mextallogenic belt of Deh Salam-Qala Zari using geochemical methods reveals deep and hidden mineralized potential areas in areas with a desert and dry desert geochemical landscape, while other conventional prospecting models is only capable of revealing the surficial tracts of mineralization.
