Dear Gamal Seedahmed,

You also can take into account the concept of segment. A lineament can be formed by several several segments or by a system of smaller lineaments. Segment networks reflect the heterogeneity of the geologic medium laterally.So lineaments have a fractal properties. For example Individual domains differing in fractal dimensions, correspond to definite tectonic blocks or structural complexes.  So also could be took into account the possible multifractal nature of the segments that forms a lineament. I also considere together with density, length, intersections, and directions, a scale analysis of the several identified segment networks that forms a linement.

You can find an examble in Vasil'yev et al 2013 2013:

you have a good concept of tectonic alignments, I suggest besides observing the temporal relationship between them, it would give an idea about the geological history of tectonic activity, it is equally important to define the families of the alignments, to observe the Current tectonic style. Just as the superposition of tectonic events.

Dear Dr. Seedahmed,

To all the aforementioned, if I were to identify any  FAULT segments (using plain photointerpretation on aerial data and simultaneous use of other type data (e.g. DEM, geophysical, seismic data, etc), I would also take into account additional elements: e.g. surrounding rock types, rock macro and micro-structure (structural deformation / texture of rocks), rock deformation, vegetation pattern, drainage pattern and density.
