For this purpose soil chemistry and the resistivity parameters such as D2 and h2 have been considered. It is observed that the bicarbonate (HCO3) shows a linear relationship with (h2), similar relations between Cl/T.H and D2 is observed where as the (HCO3) content increases with depth to the bed rock. The relationship between ratios of ions and resistivity parameters found that C1/HCO3 ratios increases with decreasing the thickness of aquifer (h2) and HCO3/T.H is increases with the increase of aquifer thickness and aquifer resistivity (h2 and D2 ). The HCO3 content of soil and C1/HCO3 ratio are the guides for aquifer thickness or weathered zone thickness in groundwater prospecting by means of soil geochemistry.
