(a) Directional filtering at 45°, with overlaid automatic lineaments extracted. (b) Corresponding lineament density map (km/km2), showing the spatial distribution and concentration of NE–SW–oriented structural features across the study area. (c) Histogram of lineament density values, displaying the frequency distribution of NE–SW trends, with mean and standard deviation indicated. (d) Rose diagram illustrating the predominance of NE–SW structural trends.
