The analysis of two radar images permits the mapping of following petrographic units: the porphyritic granodiorite of Yamoussoukro, the biotite and hornblende rich granodiorite of Toumodi, the plutono-volcano-sedimentary complex of Fetekro-Divo, the biotite-hornblende metagranite, the biotite granitic orthogneiss. It also allows the mapping of four (4) major fractures. These are: NE to NNE-SSW (ZFET and ZFTaY) fractures, NE-SW (ZFTa and ZFOT) fractures, EW (ZFO and ZFT) fractures and finally NW-SE (ZFTaHO and ZFTY) fractures. On the ground, we have distinguished three petrographic facies: syenogranites, monzonitic granites and microgranites. Six main directions of fractures were identified: sinistral N020
