Abstract : Recent sedimentation in the eastern Angola Basin includes calcareous oozes in the north and south (Guinea Rise and Walvis Ridge) and hemipelagic lutites and terrigenous turbidites on the Congo Cone and on the Angola rise and abyssal plain. Slumped and ponded sediments are dominant within the Angola diapir field. Illite and montmorillonite are abundant in the southern part of the basin, reflecting the source in soils of South West Africa and northward transport in the Benguela Current system. Kaolinite dominates the clay-mineral assemblage in the north-central part of the basin, reflecting a source in the tropical-humid Congo Basin and transport to the deep-sea through the Congo River and canyon systems. -BKA
