ABSTRACT: The Baïbokoum area offers significant potential for geological and mining exploration. However, the region is not well known due to insufficient studies on mineral and rock mapping, as well as other indicators of mineralization. In this study, we examine lithological units and potential hydrothermal alteration zones in the Baïbokoum region using remote sensing, geographic information systems (GIS), and statistical analysis, which are essential tools for geological exploration. Landsat 9 OLI data, combined with the main techniques used (e.g. FCC, BR, MNF, PCA, SEM, SAM), and field observations, are used to identify rock units and potential mineralization. Using a variety of techniques, we were able to identify orthogneisses, granites, and basalts rich in iron oxides, hydroxyl, and ferrous metals that could constitute potential mineral deposits in the Baïbokoum area. Statistical examination of the geochemical data indicates that the Baïbokoum syenites, which are calcic, alkaline-calcic, and slightly peraluminous, demonstrate that their original magma was rich in mineralization for major elements and rare earth elements, Al2O3, Fe2O3, MgO, CaO, Na2O, MnO, P2O5, V, Cr, W, Zr, Nb, Cs, Ba, Y, Hf, Ta, Th, U, and REE. In addition, the study of lineaments revealed three structural orientations in the area (NE-SW, E-W, NNE-SSW, and NW-SE). This study is innovative in that it integrates and processes Landsat 9 OLI and performs statistical geochemical analysis of previous data, and conducts field investigations. These actions make it possible to identify rock units and potentially mineralized formations, as well as to determine exploration targets.
