Organic geochemical appraisal of limestones and shales in …

The major lithostratigraphic units of the eastern Dahomey Basin are the Araromi, Ewekoro and Akinbo Formations. Field studies show that the Araromi and Akinbo Formations contain shaly facies, while the Ewekoro Formation contains essentially fossiliferous limestones. The Araromi shales are dark and bituminous, while those of the Akinbo are fissile and …

The Paleocene-Eocene limestone and shale units exposed at the Sagamu quarry, southwestern Nigeria, were investigated for the carbonate microfacies and major geochemical elements to deduce the depositional environment and the diagenetic history of the limestone. From field observations the limestone is generally massive to wavy laminated, yellowish brown to light …
