Lithostructural Mapping Using Landsat OLI images and Field Investigations in the Oumjrane–Boukerzia Mining District, Eastern Anti-Atlas, Morocco

The application of remote sensing is considered to be highly efficient in the field geology, particularly for mapping and discrimination between lithological units, as well identification different surface minerals which enable acquisition all optical radar data needed obtain more reliable particular information, especially inaccessible areas. Landsat 8 (Operational Land Imager) image bands, include color compositions 7, 4, 1, band ratios 7/5, 4/2, 3/1, 6/3, 6/1, 5/2, Principal Component Analyses PC1, PC4, PC3, directional filtering at 0° (NS), 45° (NE–SW), 90° (EW), were used analyze spectral characteristics units study area delineate alteration zones may contain significant concentrations base metals. Combined with geological observations, these integrated analyzed a geographic information system establish multi-criteria characterization mineralized zones. Hence, use contributed improvement updating available maps Oumjrane–Boukerzia area. Lineament extraction allowed performed analyses structural elements that play crucial role mineral distribution Several targeted areas examined by selective sampling. Consequently, results helped identify new important mining potential could evaluated future through detailed geophysical geochemical work.
