Photogeological, geoelectrical, and drill-hole data were used to determine the
hydrogeological conditions of the regolith layer mantling the Precambrian rocks in the …

Abstract 40 Ar/39 Ar ages of three basalt dykes that intrude the Precambrian basement in the
southern continental part of the Cretaceous Cameroon Line are presented. Specimen were …

A single zircon geochronological study of gneisses from the Obudu Plateau of southeastern
Nigeria, using the evaporation technique, indicates that zircons recorded several …

The diachronous rifting of the Pangea supercontinent, with the dispersion of the continental
masses, resulted in the formation of numerous rift systems, which primarily evolved into …

The Bouguer anomaly map of the southeastern part of the Niger Delta region of Nigeria
exhibits important anomalies that are often identified by high gradients resulting from density …

We report whole-rock geochemistry and Sr–Nd–Pb isotopic compositions of mafic dykes
intruded in the Precambrian granito-gneissic basement complex, exposed at Nyos, Batibo …

Barite deposits occur mostly as concealed mineralization dominantly in shales and

Abstract Cross River State is composed of sedimentary rocks which constitute the Calabar
Flank and metamorphic and intrusive rocks which crop out in the Oban massif and Obudu …

Rocks of the Ukwortung area of Obudu, southeastern Nigeria consist of pyroxene–biotite–,
garnet-biotite-gneisses and meta-utramafite. These rocks were intruded by various granites …
