ملخص المقالة :
The aim of this study is prospecting of iron and manganese in the Balvard 1:100000 sheet which is situated in Sanandaj - Sirjan structural zone utilizing Index Overlay and Fuzzy Logic methods in the GIS. In this study, the layers for integration, alterations, geological, geophysical, geochemical and structural data based on stream sediments, airborne magnetometeric and remote sensing studies. Based on results obtained by both of methods, Fe and Mn prospects exist in the NE and northern parts of the area. The prospect areas derived via the Fuzzy Logic method are larger than those of gained from the Index Overlay method because the method used in the range from 0 to 1 value.
