Abstract The work focused on the results of the automated extraction of lineaments and the study of geology and structural geology in the Sarpol Zahab region. Remote sensing and Geographic Information Systems (GIS) were used to extract faults and structural geology. We used principal component analysis (PCA) and directional filtering techniques applied to the Landsat 8 OLI satellite image to extract lineaments and structural geology in the study area. The shading was used to create a lineament map and a map of the structural geology of the research region. The predominant direction of the faults and lineaments is NW-SE. The density maps show a large concentration in the northwest, Southeast, and southern parts of the Sarpol Zahab area (near the MFF). We have validated these results by comparing them with geological maps and two validation criteria. First, the lithological component shows that the lineaments are often concentrated on rocks, as in the NW-SE trending surface anticlines of limestones in the Southeast and the Oligocene to Miocene sandstones and conglomerates in the West. Another component is the overlay of the lineaments on the slope map. This shows a conspicuous concentration of lineaments where the slopes are steep, and the sudden slope change is most likely the result of faulting activity. The structural lineament extraction method is acknowledged as a benefit for this kind of study and is thought to be a utility reference method with accuracy in striatal lineament selection.
