(vertical electrical sounding) study undertaken in the Ciudad Rodrigo Craben unravels the structure and the lithology of the graben infill. The basement resistivity values (200-350 Qm) indicate the presence of NW-SE oriented paleovalleys which were responsible for the tertiary drainage. The resistivity values of the tertiary rocks show the presence of sandstones and conglomerates (40-70 Qm), sand and clay (20-30 ?m) and claystone (10-18 ?m). Each of these groups can be correlated to Paleogene and Neogene rocks according to surface observations}, publisher = {Sociedad Geológica de España}, title = {Reconocimiento geoeléctrico de paleovalles en la depresión terciaria de Ciudad Rodrigo}, title = {Geoelectrical recognition of paleo-valleys in Ciudad Rodrigo Tertiary depression}, author = {Corrochano, A. and Andrés, M.
