Analyse Structurale De La Déformation Dans Les Granitoïdes Éburnéens De La Région De Doropo (Nord-Est De La Côte d’Ivoire)

Abstract : The work carried out in the Doropo region, located in the northeast of Côte d'Ivoire in the Paleoproterozoic domain, has allowed the updating of pre-existing geological information. It is an area characterized by a granite-gneissic basement and affected by an important lateritic cover. This has made the area inaccessible for a long time for any exploration work. The recent field trip carried out during this study revealed a lithology that includes biotite granite, gneissic and migmatitic granite, granodiorite, gabbro, amphibolite and rhyolite. These lithologies have been affected by major structures such as foliations, fractures, shear bands, folds and fractures. These structures are mostly oriented mainly NE-SW. This suggests that the deformation that has prevailed in the region is a NW-SE compression.
