Evaluation of the Lineaments and Faults in the Alborz Province by Remote Sensing

The studied region in this research (alborz province) is structurally located in alborz poly_orogenic system of northern iran. the purpose of this research is combining the remote sensing and geology sciences to show fault lineaments by analyzing satellite data in a vast region and also comparison between lineaments layer and recognized faults in geology maps. firstly, two scenes of landsat etm+ satellite images with 164-35 and 165-35 numbers were mosaicked and also according to coordinates of research area (46? 30´ to 48? east longitude and 34? to 35? north latitude degree) have been crop. then with remote sensing methods such as combination of bands, filtering, ndvi index to reconstruction the vegetation, principal components analysis (pca) and band relativity in gray scale and color images have been analyzed the satellite images. finally, by using the above mentioned methods, the map of fault lineaments and map of lineaments density for alborz province have been prepared and compared with recognized faults.
