Structural Analysis — Sheet 03
The combination of pole-density stereonet, rose diagram and shaded relief tests whether structural orientations have a landscape expression. Alignment is meaningful only if the datasets are independent: the DEM lineaments should be extracted without reference to the measured fault set, then compared statistically rather than visually.

Geological interpretation and evidential boundary
The combination of pole-density stereonet, rose diagram and shaded relief tests whether structural orientations have a landscape expression. Alignment is meaningful only if the datasets are independent: the DEM lineaments should be extracted without reference to the measured fault set, then compared statistically rather than visually. Scale and azimuthal sampling bias must be considered because illumination, drainage and ridge length influence apparent lineament frequency. If the dominant topographic and field orientations coincide beyond a null expectation, the result supports structural control; if not, lithology or drainage inheritance may dominate. The sheet should therefore be read as a multi-dataset correlation test, not as proof that every linear landform is a fault.
