Investigation of fault and fractures Akhlamad (north west Binalud) based on the satellite data processing and studying fractal characteristics of fracture systems

Abstract In this study, fracture systems of Akhlamad area was drawn using remote sensing methods and satellite data processing. Then their fractal pattern examined. Based on the regional fault related morphologies, different techniques were utilized to detect fault lines and fractures. To study the region, data of SPOT5, LandsatETM+ and ASTER were used. The resulting image of Landsat ETM+ merged with Panchromatic band for increasing the spatial resolution. Then the data were analyzed for detection of tectonic lineaments, lithological interruption and displacements due to faulting in ER-Mapper, ENVI and ArcGIS softwares. Also, Sunshading method was used on the DEM for detecting roughness caused by faults. Finally, the structural map of region was constructed using the fractures detected by the above mentioned techniques. Then, the fractal pattern of the structural fracture zone have done by Box-counting algorithm. For this purpose, the study area is divided into 94 separate areas and each area was analyzed separately. Based on the results, the fractal dimension is more in the direction NS, NNW-SSE and EW. Because the D value increases in these directions that has reached to 1.6. In other words, the directions have been developed further during the structural transformation. Given the certainty of these three direction, reactivation this area undertaken along these three.
