Lithology and Structural-Deformation Control Fracture-Intensity, Topology, and Geometry in Triassic Red-Beds, Argana Corridor, High Atlas, Morocco

Summary Fractures play a crucial role in fluid flow within low-permeability formations, making their characterization essential for hydrocarbon reservoirs, groundwater management, CO2 storage, and geothermal energy exploitation. This study investigates fracture networks in the Triassic red beds of the Argana Corridor, High Atlas, Morocco, focusing on their structural and lithological controls. However, fracture connectivity is inherently complex due to multi-scale structural variability. A multi-scale approach is adopted to analyse fracture networks, integrating data from field observations, drone photogrammetry and satellite remote sensing. This work presents the preliminary results obtained from the processing and analysis of remote sensing data. The results reveal that fracture intensity increases near fault zones, with significant variability depending on facies. Fault-damaged areas exhibit higher connectivity and fractal complexity, influencing fluid migration pathways. By quantifying fracture attributes and their evolution relative to structural features, this study enhances predictive models of fracture connectivity and fluid flow. The findings contribute to improving reservoir characterization and geohazard assessment, with implications for energy and water resource management.
