Integrated Sedimentology, Organic Geochemistry, and Depositional Environment of the Ogwashi–ASABA Formation at Mgbiligba Spring, Southern Nigeria

Oludewa Joseph Mode · Asian Journal of Geological Research · 2026

Despite the hydrocarbon significance of the Ogwashi–Asaba Formation in the Niger Delta Basin, integrated sedimentological and organic geochemical investigations of the Mgbiligba Spring exposure remain limited, resulting in an incomplete understanding of its depositional history a...
