Geomagnetic Signature Pattern Of Industrial Layout Orile Igbon

Ground magnetic data at Industrial Layout Orile Igbon was analyzed with a view to determining the areas that are competent for the construction of factories and other related buildings (e.g. high-rise administrative buildings). The study area falls within latitude 080 13′ 59.22″ to 080 15′ 0″ North and longitude 0040 17′ 05.0″ to longitude 0040 19′ 01.1″ East of Southwestern Nigeria. The ground magnetic survey was carried out, the acquired data was processed and analyzed. The qualitative interpretation revealed features like faults, contact between two rocks and fracture zones. However, the quantitative interpretation gave the overburden thickness to the top of the magnetic basement rock as varied between 6.0 and 33.5 m. Interpretation of ground magnetic data revealed that Industrial Layout Orile Igbon comprise of zones underlain with thin as well as thick overburden. It is therefore advisable that people should not ignorantly built factories making use of heavy machines where there is thick overburden as it might lead to subsidence or total collapse in the future. This could occur when the vibration of these heavy machines is transferred to the subsurface which might lead to ground motion which later has effect on the factory’s foundatio
