The modeled curve for VES 7 to VES 10.The modeled curves showed threelayers in nine of the VES stations(i.e. VES 1, 2, 3, 4, 5, 6, 7, 9 and 10)and four layers in the remaining one(i. e. VES 8) (figure 3a–b). The resultshowed that 60 % of the VES stationshave thin overburden and fresh basementrocks (i.e. VES 1, 3, 4, 5, 7 and10), 20 % of the VES stations havethick overburden and fresh basementrocks (i.e. VES 8 and 9) while theremaining 20 % of the VES stationshave thick overburden and fracturedbasement rocks (i. e. VES 2 and 6).From the results, VES 2 and 6 arethe best location for groundwaterprospect because of the thick overburdenand fracture in the basement(Wright, 1990; Meju et al., 1999).VES 8 and 9 could be consideredas another location for groundwaterexploration because Benson& Jones (1988) and Lenkey et al.(2005) reported that boreholesshould be sited where the regolithis thickest.Summary of the formation ofthe layer parameters is presentedin table 1 while summary ofclassification of the resistivitysounding curves is presented intable 2.RMZ-M&G 2012, 59
