(a) Directional filtering at 135°, with overlaid automatic lineaments extracted. (b) Corresponding lineament density map (km/km2), showing the spatial distribution and concentration of NW–SE–oriented structural features across the study area. (c) Histogram of lineament density values, displaying the frequency distribution of NW–SE trends, with mean and standard deviation indicated. (d) Rose diagram illustrating the predominance of NW–SE structural trends.
