application of fuzzy gamma operator for mineral prospectivity mapping, case study: sonajil area

The sonajil area is located in the east azerbaijan province of iran. according to studies on the geological structure, the region has experienced intrusive, subvolcanic, and extrusive magmatic activities, as well as subduction processes. as a result, the region is recognized for its high potential for mineralization, particularly for cu-au porphyry types. the main objective of this research work is to utilize the fuzzy gamma operator integration approach to identify the areas with high potential for porphyry deposits. to carry out this exploratory approach, it is necessary to investigate several indicator layers including geological, remote sensing, geochemical, and geo-physical data. the analysis reveals that the northeastern and southwestern parts of the sonajil region exhibit a greater potential for porphyry deposits. the accuracy of the resulting mineral potential map (mpm) in the sonajil region was evaluated based on data from 20 drilled boreholes, which showed an agreement percentage of 83.33%. due to the high level of agreement, certain locations identified in the generated mpm were recommended for further exploration studies and drilling.
