The stratigraphic relationship of the three terminal Cretaceous formations in the Upper Benue Basin (Northeastern Nigeria) has hitherto remained unclear. The sequence: Sukuliye (Sekule) Shale (oldest), overlain by Numanha Shale and then Lamja Sandstone (youngest) erected by pioneers, has been accepted by some later workers and modified or rejected by others. Employing paleontological and sedimentological evidence, the fo rmations are shown here to be, in part, laterally equivalent. Zusammenfassun g. Die stratigraphische Beziehung der drei terminalen Kreide-Formationen im Oberen Benue-Becken (NE-Nigeria) ist bislang unklar geblieben. Die Sequenz : Sukuliye (Sekule) Shale (unten) Numanha Shale (Mitte)-Lamja Sandstone (oben), aufgestellt durch die Pioniere, wurde von einigen spateren Bearbeitern anerkannt und von anderen modifiziert oder abgelehnt. Auf Grund palaon tologischer und sedimentologischer Befunde wurde nunmehr festgestellt, daB die Formationen teilweise nichts anderes als laterale A quivalente sind.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
