Abstract The study aims to investigate the groundwater potential in Ladirin Estate, Abeokuta, Ogun State, Nigeria, using Vertical Electrical Sounding (VES) resistivity methods. The research focuses on characterizing the subsurface layers, identifying aquifers, and determining the best locations for boreholes. Fifteen VES points were evaluated, and the resistivity data was analyzed using Winresist software. The results revealed five geoelectric layers: topsoil, sand/lateritic sand, dry sand, a...
ABSTRACT Studies on the distribution, sources and impacts of Heavy Metals (HMs) and Polycyclic Aromatic Hydrocarbons (PAHs) in soils and sediments of Urbanised Industrialised Cities (UICs) are integral part of environmental monitoring programme globally. Results from such, have been used to design appropriate mechanisms for the sustainable use of environmental media. However, several Nigerian UICs, such as Onitsha, the most industrialized city Southeastern Nigeria, have not been adequately st...
Geophysical investigation involving the electrical resistivity method was carried out at a site earmarked for construction of a Lecture Theatre at the Obafemi Awolowo University Teaching Hospital Complex (OAUTHC) in Ile-Ife, Osun State Nigeria. The aim was to generate 2-D subsurface images beneath the site which will provide the required geological information for location and design of the building foundation. The geophysical investigation involved the 2-D imaging technique which utilized ...
ABSTRACT Aeromagnetic data over some part of the Chad Basin, Nigeria was analyzed. The aeromagnetic anomaly map, its qualitative and quantitative interpretation helped in identifying the nature and depth of the magnetic sources in the study region. The regional-residual separation was performed with a first order polynomial using oasis montaj software. The residual data obtained was contoured into 3-D maps and this revealed two prominent magnetic anomaly source intensities; the low freque...
In the field of geosciences, large sum of data are always acquired, processed and interpreted for different geographic locations, but only few of the data are well managed, such that, they can be useful for subsequent geoscience related surveys carried out in the same geographical locations. This is a challenge in the geoscience field, and it would be beneficial to the field when this challenge is resolved and it becomes a utilisable concept. It is in this regard that a database mana...
