    COVER: The Bentiaba Basanite (Angola) formed during a Late Cretaceous (post-rift) regional igneous pulse. Lava flows at the top of the cliffs are fed by northwest-southeast–trending dikes (seen in foreground), which mirror earlier syn-rift fault trends. Post-rift igneous activity is thought to have heavily influenced petroleum prospectivity in the highly prolific central South Atlantic “pre-salt”. See Rochelle-Bates et al., “Geochronology of volcanically associated hydrocarbon charge in the pre-salt carbonates of the Namibe Basin, Angola”, p. 335–340.
