Alternative global Cretaceous paleogeography
Plate tectonic reconstructions for the Cretaceous have assumed that the major continental blocks—Eurasia, Greenland, North America, South America, Africa, India, Australia, and Antarctica—had
Petroleum Geology of Cretaceous-Tertiary Rift Basins in Niger, Chad, and Central African Republic
This overview of the petroleum geology of rift basins in Niger, Chad, and Central African Republic (CAR) is based on exploration work by Exxon and partners in the years 1969-1991. The work included
Paleogeographic and structural evolution of northwestern Africa and its Atlantic margins since the early Mesozoic
The geological evolution of northwestern Africa and its continental margins is investigated in the light of nine Meso-Cenozoic paleogeological maps, which integrate original minimal extent of


Stratigraphic Evolution of the Benue Trough and Its Implications for the Upper Cretaceous Paleogeography of West Africa

The main stages of tectonic evolution of the Benue Trough are well documented in the stratigraphic succession, basically comprising three depositional sequences: an Albian-Cenomanian pyroclastic,
Nigerian Late Cretaceous Stratigraphy and Paleogeography
Two principal Upper Cretaceous sedimentary successions in Nigeria show considerable hydrocarbon prospects, especially in parts of southeastern Nigeria. The first succession, of Albian to Santonian
Paleocene Benthonic Foraminiferal Biostratigraphy, Biogeography and Paleoecology of Libya and Mali
The Paleocene of Mali is developed along the inner shelf margin of a broad, shallow seaway which extended from Algeria to northern Nigeria. The Paleocene of Libya is developed in a structurally
Biostratigraphical dating of the early history of the South Atlantic Ocean
The southern Atlantic has always been a favoured testing ground for the hypothesis of continental drift. Apart from the remarkable agreement in the geographical shape of the coast of western Africa
Stratigraphic history of the south-central Saharan region
Analysis of the exposed marine and marginal marine strata in northwestern Nigeria and the neighboring Niger Republic (southeastern lullemmeden basin) permits Stratigraphic correlations throughout the
Evidence for an open seaway between northern and southern proto-Atlantic in Albian times
SINCE Wegener1 presented his hypothesis on the origin of continents and oceans much effort has been centred on the dating of the first opening of a southern proto-Atlantic and on that of a first
Relationship between eustacy and stratigraphic sequences of passive margins
It is commonly thought that transgressive or regressive events that may have occurred simultaneously on geographically dispersed continental margins have been caused by worldwide sea-level rise or
Structural History of Atlantic Margin of Africa
Basin development on the Atlantic margin of Africa, according to seismic evidence, began with rifting, in an alluvial and lacustrine environment, followed by regional subsidence and later marine

The real ocean surface-the equipotential surface of the geoid or the geodetic sea level-is rough and uneven and characterized by humps and depressions of several meters. The present geoid
