Ground-Magnetic Study Of Ijapo Area Of Akure, Ondo State, Nigeria

Abstract

Ground-magnetic survey of Ijapo area in Akure township which is situated in the western part of Nigeria and falls within the Precambrian basement complex terrain of the country was carried out with the intention of determining and establishing the geologic structures, its potential for groundwater accumulation and development.
Twelve traverses were established for the survey. The results presented as profiles, geomagnetic sections and ground-magnetic contour map showed that the low magnetic intensities are reflection of fractures, faults and joints, which are indicators of basement aquifers. Quantitative interpretation of the results showed that the overburden thickness ranges from 25.0m - 3.0m. The thin regolith underlined by fractures is relevant and adequate as well for groundwater wells.
