Abstract

The paper shows that isoresistivity contours for different depths, drawn from interpreted resistivity values, can indicate the location of underground lineaments. A comparison of the surface lineament map with the maps of isoresistivity contours for different depths shows that many of the underground lineaments recognised through the resistivity studies have surface expressions as lineaments. The underground lineaments allow largescale migration of groundwater and can be used as sites for the artificial recharging of aquifers. It is concluded that the maps prepared from interpreted resistivity values derived by curve matching can give a better picture of the underground structures than the conventional maps prepared from apparent resistivity values.
