摘要
The study area is located in south of Khorasan-Razavi province. This region is part of central Iran, which is of high significance due to existence of metal and non-metal deposits. Considering the location of the study area, the lithology and metal-mineral indices of Dolat-Abad sheet, it can be said that their metallic deposits are economically feasible. Hence, this region is considered promising for exploration of metallic deposits. In order to achieve this goal, at first, the region’s alterations were detected by using OLI-ASTER images in ENVI software. After processing the lithogeochemical data in SPSS and GIS software, anomaly map of studied elements was obtained. Using geological map, different layers such as lithology, faults and indices were obtained. Eventually, by preparing the layers and incorporating those using the index overlay GIS modeling, promising mineralization areas in the region were identified. Results show that a significant Cu-Au mineralization has occurred in the south western region of the study area.
