Article Title: Geophysical Study of Limestone Attributes At Abudu Area of Edo State, Nigeria
by F.O. Ezomo and C.N. Akujieze

The need to prospect for limestone geophysically became inevitable in view of the fact that limestone rock is a vital building stone normally employ for the manufacture of cement and concrete which is of economic importance to Nigeria in particular and the world in general. The investigated limestone attributes in this study therefore include its depth, thickness below sea level or earth's surface. Geophysical study of limestone attributes was investigated by electrical resistivity survey method in Abudu Area of Edo State, Nigeria. This investigation actually entailed carrying out electrical resistivity survey of vertical electrical sounding (VES) employing Schlumberger array. Ten (10) VES, fairly distributed in eight different stations of Abudu area were carried out. The software IP12WIN utilizing computer iteration was used for interpretation of apparent resistivity data. The result of the electrical resistivity survey showed that limestone was intercepted at a depth varying from about 10.0m to 60.0m while the thicknesses varied from about 5.0m to 50.0m. The resistivity of the limestone formations varied from about 30,000 to 400,000 ohm-m. Area of probable limestone formations and their thicknesses have been identified especially for future mining of industries foundation, operations and drilling.
