Physical properties of sediments from the continental margin of western Africa
Abstract
After initial build up of the west African continental margin, sedimentation was predominantly biogenic. The physical properties of the sediments from this area are generally related to rock type and follow the general trends of increasing density, increasing sonic velocity and decreasing porosity with depth except where abrupt lithologic changes are encountered. Physical properties data suggested that significant amounts of overburden were removed from portions of the Cape Basins and the Walvis Ridge. At a site in the cape Basin results of consolidation testing suggests that approximately 130 meters of overburden are removed.
