The analysis of the dynamics tectonic Morvarid Fault at Main recent Fault using remote sensing data and fractal analysis

The aim of this study is assessment the dynamics tectonic Linements and fractures related is to the Morvarid Fault, middle segment of the Main recent Fault (MRF).The MRF is a dextral strike-slip fault the with northwest-southeast trend, composed of several fault segments. The Morvarid Fault is one of the MRF segments with a .bout 30 kilometers length is located in middle part and continuation of the Sahneh fault. In this study, using remote sensing techniques and fractal analyzes, faults and Linements associated with the fault zone Morvarid examined the method used in this study, semi-automatic extraction Linements based on STA algorithm of images Landsat satellite and is shaded models. Using fractal analyzes, lineaments and faults were obtained analyzes the fractal dimension reflects the increasing the density of fractures around the fault zone MRF and the density in a process northwest southeast and parallel to the fault. Fractal dimension faults from northwest to southeast is gradually changed from 1.626 to 1.847 and this increase of fractal dimension, is also visible in the Linements from 1.811 in the northwest to 1.941 southeast will rise. In fact, factor in the rise fractal dimension in the study area, related fractures Main recent Fault, which away from this zone the faults density decreases.
