چکیده

Identification of hydrothermal alterations is regarded as a crucial factor in mineral exploration. Additionally, identifying and mapping structural zones is of particular importance. In this study, ASTER and OLI satellite images were utilized to identify hydrothermal alterations employing statistical methods (band ratios and principal component analysis), and Sentinel-2A images were employed to identify geological units, faults, and calculate photolineament factor in the Ferdows-Gonabad-Bajestan metallogenic area. Stream sediment and rock samples collected from the area were examined for Ag, As, Au, Co, Cu, Fe, Mo, Pb, V, and Zn elements. The results were then combined using fuzzy OR operators. Subsequently, all data were valued using the analytical hierarchy process, weighed, and integrated with GIS software. Based on the results, five areas were identified as mineral potential zones, among which areas A, B, and C, have a higher probability of mineralization due to higher grades of elements. Sampling from the area, thin section preparation, and XRD analysis were also conducted for result validation with a validation accuracy of 90% and a kappa coefficient of 0.89.
