    <abstract>Ce travail concerne une zone à cheval sur le Ghana, le Togo, le Bénin, le Burkina Faso et le Niger. Il permet une meilleure connaissance de l'évolution du bassin des Volta et des caractéristiques de la tectogenèse panafricaine. La zone étudiée comprend le craton ouest-africain, le bassin des Volta, les unités externes des Dahomeyides et le "craton bénino-nigérian"</abstract>
