Abstract:
The occurrence of sandstone deposit in Ozalla village area of Edo state, Nigeria was detected geophysically by using vertical electrical sounding (VES) techniques of electrical resistivity method. The urgent need to prospect for sandstone deposit in the area became imperative in order to arrest youth restiveness in the area by way of setting up chemical industry that rely on sandstone as raw material for its manufacture purposes. The prospected sandstone properties include its thickness depth below sea level and types of rock above it. Twelve (12) fairly distributed VES in three (3) different regions, employing six (6) points per decade were carried out by using the commercially available terrameter equipment to justify the operation of collecting, apparent resistivity data. The resulting apparent resistivity data was interpreted by using the IP12WIN software utilizing computer iteration. The result of the geophysical survey showed that sandstone deposits were intercepted at depths varying from about 0.45m to 82.00m while the thicknesses varied from about 0.40m to 45.00m. The resistivity of the sandstone deposit varied from about 200.00hm - m to 21000.0 ohm - m. Area of probable sandstone deposits have been identified for future mining, of industries, foundation, operation and drilling
