Paleogeography, sedimentation and tectonics of the upper cretaceous Anambra basin, southeastern Nigeria

Geochemistry of carbonate cements in Cretaceous sandstones, southeast Benue Trough, Nigeria: Implications for geochemical evolution of formation waters

“…Sandbodies occur in Asu River Group, Eze-Aku Group and the Cretaceous proto-Niger Delta sediments and were deposited as deltaic complexes during regressive phases. These stratigraphic sandbodies have been reviewed and discussed in terms of depositional characteristics and geometries (Ladipo, 1988;Ojoh, 1990). Some of the sandstones in the Albian, Turonian-Coniacian and Campano-Maastrichtain sequences are considered potential reservoir rocks (Whiteman, 1982;Ladipo, 1988).…”

The stratigraphic and sedimentologic history of the Benue Trough is well documented in Petters (1978) and Wright (1981).…”

Sedimentology and Permeability Distribution of the Ajali Sandstone around Odugbo, North Central Nigeria

“…The Basin has been extensively studied by various workers (Akande et al, 2007;Okogbue et al, 2012) for its coal and shale characterization. The paleogeography, sedimentation and tectonics are documented by such works as Murat, 1972;Ladipo, 1988;& Obi et al, 2001). According to Murat (1972) and Obi et al (2001), the tectonic evolution of the southern sedimentary basin probably started in Early Cretaceous times with the formation of the Benue-Abakaliki Trough as a failed arm of the rift triple junction associated with the separation of African and South American continents and subsequent opening of the South Atlantic.…”

Palynomorphs of the First Down-Hole Shale Occurrence in Three Contiguous Basins in Nigeria: Implication on the K-Pg Boundary

“…Folding in the Abakaliki-Benue trough axis caused a change in sedimentation axis southward leading to the formation of the Anambra Basin. The Anambra Basin is a synclinal structure consisting of more than 5,000m thick of Upper Cretaceous to Recent sediments representing the third phase of marine sedimentation in the Benue Trough (Ladipo, 1988;Akande and Erdtmann, 1998). The Bida Basin is often taken to be a northwesterly extension of the Anambra Basin or an extension (N/W-S/E) of the Benue rift.…”
