Mapping of Hydrothermal Alteration Zones in the Kelâat M’Gouna Region Using Airborne Gamma-Ray Spectrometry and Remote Sensing Data: Mining Implications (Eastern Anti-Atlas, Morocco)

The mapping of hydrothermal alteration zones associated with mineralization is paramount importance in searching for metal deposits. For this purpose, targeting by analyzing airborne geophysical and satellite imagery provides accurate reliable results. In the Kelâat M’Gouna inlier, located Saghro Massif Moroccan Anti Atlas, natural gamma-ray spectrometry ASTER data were used to map zones. Natural processed produce maps Potassium (K %), Uranium (eU ppm), Thorium (eTh ppm) ratios K/eTh K/eU. addition, four-band computed, on data, distribution clay minerals, phyllitic propylitic iron oxides. combined results obtained from further exploited fuzzy logic modelling using Geographic Information System (GIS) generate a mineral prospectivity map. Seven likely be favorable have been identified. They show spatial correlation (i) known surface prospects occurrences, (ii) granite-encasing contact zone, (iii) fault (Sidi Flah Tagmout faults). This research therefore important information prospecting potential study area.
