Abstract

Abstract
Geophysical exploration based on a two-dimensional electrical resistivity survey was carried out to determine the presence of construction clay deposits in Ologbo Area of Edo State, Nigeria. Begin and end co-ordinates for line 1 were N6°05.585′, E005°39.686′ and N6°05.541′, E005°39.652′ and N6°03.754′, E005°39.029′ and N6°03.700′, E005°39.054′ for line 2. The survey technique utilized was Wenner-Schlumberger array in the two explored areas to justify the operation of assembling apparent resistivity data. Significantly, clay finds its use in the steel industry where it is used to make refractories. Petrozenith earth resistivity meter, 21 electrodes, 4 cables cases and a GPRS device comprised the field equipment. The data recorded after prospecting with maximum current electrode spacing of 100.0 meters was interpreted using Zondres2D computer program to produce true resistivity models. Geologic interpretation of the survey revealed that clay and clayey soil were present intermingled with pure silt and traces of fine sand deposits. The depths of clay formations were measured at 4 meters and 12 meters for survey line 1 and survey line 2, respectively. Areas of probable clay formations have been identified especially for future exploitation.
Keywords: 2-D resistivity survey, construction clay, refractories, pseudosection.
