Crustal Evolution of Southern Part of the Ferkessédougou Batholith (Côte d’Ivoire, West African Craton): Implications for Baoulé-Mossi Domain Geodynamic

The southern Ferkessédougou batholith in the center-west of Côte d’Ivoire is study area. geology this area includes granitoids (granodiorite, two-mica granite, biotite granite and muscovite granite) metasediment panels. Petrographic studies were coupled with geochemical analyzes on whole rock order to provide new elements structural evolution portion West African craton. data show that basement Bonon partly identical northern part batholith. reveal three major phases deformation structured As for carried essentially samples granitoids, they indicated a high-k affinity I type characteristics. spectra REE normalized chondrites, have moderate slopes fractionation highlighted by ratios (La/Sm)N = 1.93 - 4.56 (La/Yb)N 7.69 32.28. multi-element diagrams revealed negative anomalies Ta-Nb implying partial melting crust TTG composition. Studies geotectonic environment shown Bouaflé region emplaced an arc associated subduction zone.
