Lineaments Extraction and Analysis Using Landsat 8 (OLI/TIRS) in the Northeast of Morocco

Northeastern Morocco is made up of several units belonging to the Alpine belt and its foreland. Miocene plio-quaternary volcanic rocks with variable mineralogy geochemistry dominate geology this region. The presence active faults in different directions explains high tectonic instability frequency earthquakes. This study contributes effort understanding geothermal potential Northeast Morocco. Heat source permeability are both key factors process. Indeed, lineaments analysis constrains structures their indicates severely faulted zones, which most promising areas for exploration. For purpose, we used Landsat data combined geological structural maps available Different image processing techniques were applied including band ratio (6/2) directional filters. To validate results, conducted a comparative between linear structures, data, previous studies. Results automatic extraction method from 8 OLI/TIRS indicate three main lineament systems: 1) NE-SW system ranging N40 N70; 2) an N-S N10 N45; 3) EW WNW-ESE systems N80 N120. Most extracted localized Kebdana, Amejjaou, Nador Melilla regions. Compared studies, consistent extensive period (Tortonian Pliocene); NW-SE last compressive episode (Pliocene); first (Late/End Tortonian).
