The DIVA results indicate that the Maestrichtian to Paleocene sediments in the southern and mainly in the southwestern sector of the Anambra basin should be the major sedimentary strata with liquid hydrocarbon potentials, whereas the Lower Cretaceous and particularly the Santonian sediments exhibit the highest potentials for gaseous hydrocarbons.

Shallow carbonates recovered from several sites along the Ninetyeast Ridge evolved from Campanian (approximately 80 million year old) algae and coral-rich limestones at the most northern site, Maestrichtian (about 70 million year old) shallow carbonates farther south, Paleocene (some 63 million year old) gastropods, bivalves, and echinoderms at a more southern site, and, finally, at the most southern site, a middle/upper Eocene to lower Oligocene (52 to 30 million year old) faunal assemblage.
