Change in saturation levels occurs in reservoirs during hydrocarbon production resulting in fluid
replacement. This impacts on the mechanical and elastic properties of reservoirs and consequently,
alters production model ...
Over the years, various biostratigraphic approaches (foraminifera, pollen and spores)
have been used for determining age and biozonation which are useful for exploration
and production activities in the Niger Delta. ...
Agricultural soil nutrients variability assessment for sustainable crop production has
usually been through soil geochemical/chemical analyses which are laborious and
expensive, thus necessitating the need for faster and ...
The adoption of Open Pit Slope Design (OPSD) used in exploitation of minerals is known to impact mining outputs and safety if slope stability is properly determined. However, slope stability is dependent on the understanding ...
Boreholes and wells are the most reliable sources of groundwater in Lokoja and its environs. Some aspects of hydrochemical properties of the groundwater resource have been assessed. However, stable isotopes characterisation ...
The associated sulphide mineralisation provinces comprising lead-zinc ore in Nigeria have
always been associated with the sedimentary Benue trough. However, there had been reports of
associated sulphide mineralisation ...
Talc is formed from diverse geological processes including hydrothermal alteration and contact or regional metamorphism of mafic, ultramafic rocks and dolomitic carbonates. Previous studies on the genesis of talc deposits ...
Geological Transition Zones (GTZ) are hydrogeologically problematic, owing to poorly defined basal and lateral contacts between the lithological units that make up the zones. Attempts have been made to delineate the complex ...
Pegmatites hosta variety of economic rare metals and this has led to increased search and study of pegmatite belts globally. The Nigerian pegmatites belts continue to attract considerable attention due to their economic ...
Okemesi-Iwaraja area lies within the Ilesha Schist belt, and has been described as a polydeformational
high strain transcurrent shear belt in the Basement Complex of Southwestern Nigeria. In addition, the
structures, ...
Paleomagnetic characteristics of iron-oxide in Precambrian Basement rocks documents orogenic
events in those rocks and has been used to decipher the evolution of such rocks world-wide. Previous
studies on paleomagnetism ...
Shale is an important geological material useful in the production of ceramics, building materials and other chemical products. The Mamu and Nkporo shales have been studied mainly for their stratigraphic and sedimentary ...
The Basement Complex rocks of Southwestern Nigeria have been mapped regionally on a scale of 1:250,000. On this scale, many rock units are grouped together with very limited information on component members. However, such ...
Metal recycling, smelting and mining activities are potential contributors of heavy metal
in soils, as the soil is the recipient of stockpiled scraps and discharged effluents from the
activities. Metal recycling and ...
The Lower Benue Trough (LBT) is a clay-shale rich basin with lots of industrial clay deposits with
considerable economic value. Previous studies focused mainly on the geochemistry and mineralogy of
the clay deposits ...
Anambra Basin is an inland sedimentary basin with oil, gas and coal deposits. Previous palynological studies from the basin were mostly from outcrop samples which are insufficient for detailed palynozonation and ...
Exploration and production activities in the oil industry involve huge financial resources and in order to reduce associated economic risks, adequate uncertainty quantification and reserve evaluation are required. This ...
Geochemical assessment of fluid inclusions in minerals has been successfully used in the description of genesis and characteristics of different ore-forming fluids. However, there are few reported applications of fluid ...
Pegmatites (mineralised and barren) occur as intrusive bodies within the basement rocks of southwestern Nigeria. They are overlain by residual lateritic profiles which hinder access to the rocks thus making the discrimination ...
Globally, nearly half of human population relies on groundwater for various uses. However, the occurrences of this vital resource are usually constrained in areas underlain by crystalline bedrocks. This is more critical ...
