Mineralogical mapping using Landsat-8 OLI, Terra ASTER and Sentinel-2A multispectral data in Sidi Flah-Bouskour inlier, Moroccan Anti-Atlas

The massif of Saghro in Moroccan Anti-Atlas is known for several important economic deposits. Thanks to its high potential in terms of production, the deposit of Bouskour is considered among the most important and promising ones on the national scale. The objective of this work is to evaluate the potential of the new Multispectral Landsat-8 OLI and Sentinel-2A sensors in comparison with the Terra ASTER sensor in mineralogical mapping. This task was completed using the band ratio (BR), independent component analysis (ICA) and mixture tuned matched filtering (MTMF) methods. In addition, a field survey was carried out in order to control and validate the obtained mineralogical abundances. The approach followed gave satisfactory results with respect to the field data and the previous studies. Therefore, the sensors used showed great potential for mineralogical mapping and they can be exploited in other regions.
