Summary:The petrography and structure are described of several schist belts occurring in a 400 km-wide, NNE-trending zone parallel to the Pan-African province/West African craton boundary. The schist belts fall into two age groups. The earlier group is characterized by coarse-grained metasediments and mafic igneous rocks, complex structural styles and extensive invasion by Pan-African granitic plutons. Ages of approx 1100 m.y. have been obtained from schists and gneisses adjacent to these belts and the group is assigned to the Kibaran orogeny. The later group is characterized by fine-grained clastic sediments, insignificant mafic rocks, a simple structural style and lack of granite plutons; it is ascribed to the Pan-African orogeny.
