Abstract
This research was conducted with the aim of analyzing the relationship between geological structures, the alteration and mineralization of porphyry copper deposits in the central part of the Dehaj-Sarduiyeh magmatic belt of Kerman province. In order to extract fractures, non-directional and directional filters were implemented on Sentinel 2, Landsat 9 satellite images, and the digital elevation model (DEM). The structures analysis was done using Fry and lineament density methods. In addition, hydrothermal alteration zones were enhanced by implementation of the logical algorithm method on the Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) images. Comparison of the structural analysis with the discriminated hydrothermal alteration map showed that there is a logical relationship between the lineament density and the position of the copper deposits. The rose diagram of the fractures shows the northwest-southeast and northeast-southwest trend, which is consistent with the rose diagram trend of the porphyry copper deposits at the region. The results of this research showed that Fry's method can be used in structural analysis for the exploration of porphyry copper deposits
