Abstract

This study employs Vertical Electrical Sounding (VES) to investigate subsurface lithology with emphasis on identifying marl deposits in the study area. Resistivity profiles from five locations reveal diverse geological formations, including shallow weathered zones and deeper high-resistivity layers consistent with dense marl and sandstone. Results indicate that marl-rich formations occur at extractable depths. Overlying clay and shale horizons, identified as low-resistivity layers, may act as protective aquitards. These findings demonstrate the effectiveness of VES in delineating marl deposits and assessing their spatial distribution. The integration of recent advances in geophysical surveying and resistivity inversion enhances the accuracy of locating economically viable marl deposits, supporting sustainable extraction and land-use planning in sedimentary environments
