Geomagnetic and Geoelectric determination of Topography and Depth of constituent Bedrock in a Complex Environment.

Abstract

Geomagnetic and geoelectric surveys were executed in a complex zone with the aim of determining the topography and estimated depth of constituent bedrock in the study area. The ground magnetic and geoelectric – Schlumberger’s vertical electrical sounding – methods were applied for this study. The presence of a depression was observed between two high relief bedrocks establishing the presence of an undulating topography with the range in depth to bedrock being 2 – 20 m. It was suggested that appropriate measures be employed in the location if it is considered for complex engineering purposes.
