62 vertical electrical soundings (VES) were carried out to map limestone deposits of Ewekoro formation, south-western Nigeria. The maximum current electrode spacing AB/2 was 1 km. The results revealed the occurrence of limestone in all the locations within the third and fourth geoelectric layers with resistivity values ranging from 10 to 100 KWm and thickness range of 15 to 90 m. The resistivity values of the limestone samples collected from the study site were also analyzed by laboratory direct method. This direct method revealed that the resistivity values fall within 6 and 171 KWm. The two approaches showed a good degree of correlation in the resistivity value of the limestone and their varying qualities. This research work further showed the occurrence of vast deposit of limestone, which can be of economic importance in mining and industrial purposes.

 

Key words: Resistivity, limestone, geoelectric layer, permeability, Ewekoro formation.
