This research, carried out in Anikro sector, located in north-west of Toumodi, in central Côte d’Ivoire, proposes to bring geology clarifications of this part of Ivorian territory from geophysics survey. The results reveal two lithological sets, one magnetic, poor in radionuclides, especially Potassium (K) and the other weakly magnetic, with high content certain radionuclides such as Potassium. Magnetic unit consists basic volcanic and plutonic rocks (basalts, pyroclastits, gabbros, volcano-sediments, green rocks) and weakly magnetic set consists volcanic and plutonic acid formations (granits, granodiorites, metarhyolites) probably in intrusion into volcano-sediments.
Structurally, a thrust fault system with N-S, NNE-SSW, NE-SW, ENE-WSW and E-W preferential directions that could correspond to narrow shear zones has been identified. This fault system could be metalliferous mineralization site associated with Birimian formations.
