ESTIMATION OF LATERITE DEPOSIT IN UNIBEN AREA OF EDO STATE USING 2D ELECTRICAL RESISTIVITY TOMOGRAPHY (ERT)

ABSTRACT

This project aims to use the 2D Electrical Resistivity Tomography (ERT) method to estimate laterite deposits in the University of Benin (UNIBEN) area of Edo State. Chapter One provides details on the study area's location, geomorphology, and climate. Subsequent chapters cover the basic principles of electrical resistivity, including theory, electrode arrays (Schlumberger and Wenner), and the Dipole-Dipole method. Chapter Three outlines instrumentation and methodology for the resistivity survey, including geophysical instrument selection, survey planning, and field procedures for Wenner and Dipole-Dipole arrays, as well as the Schlumberger array. Chapter Four presents results and discussions, with a qualitative interpretation using the Dipole-Dipole array, and includes a comprehensive discussion of findings. Chapter Five summarizes conclusions and recommendations, highlighting main discoveries and suggesting future actions. Throughout, 2D ERT is shown to be an effective method for estimating laterite deposits in the UNIBEN area, proving its potential as a valuable tool for geological investigations. The references section lists sources used for this project. The use of 2D ERT in estimating laterite deposits can significantly enhance the understanding of geological characteristics in the UNIBEN area, contributing to various developmental and environmental purposes.
