Conclusion
The lithostratiaphy of the study area consists of a complex basement of metasediments (argillite sandstone and wacke). Then appear the intrusion of the Ferkéssedougou granite, granodiorite and tonalite. Later, diorite dykes crosscut the metasedimentary and the tonalite. Gold mineralization exhibits two forms. Quartz veins control the highest gold grades hosted in tonalite and in contact with metasediment. This mineralization took place during the second phase of deformation characterized by the S2 shearing foliation NNE orientation with a strong dip generally towards the SE but also towards the NW. Finally, the mineralization is affected by the D3 deformation induced by diorite dykes, responsible for another gold mineralization.
