ABSTRACT: Plutonites are part of the set of crystallines compose the Precambrian
basement. Their study is capital because it allows participating in the debates
on the geodynamic evolution of the West African craton. This study concerns
granitoids and dioritoids of the North-East of Côte d’Ivoire located in the
Man-Leo ridge structured by Eoeburnean magmatism. The petrographic and
geochemistry constraints make it possible to say that these rock formations
have evolved by the process of fractional crystallization. They have a hybrid
origin (mantle and crust), metaluminous to peraluminous highlighted by geochemistry. Concerning the geotectonic context,
these plutonites of the Baoulé-Mossi domain are emplacement in a context
of subduction more precisely in a context of volcanic arc.
