A bstract In the region covered by the paper, electrical methods have been applied in four different zones:a) Ales‐Maruejols Basin (resistive lower Oligocene blanketed by conductive Upper Oligocene); b) Ledignan and Vaunage‐Lunel anticlines (faulted structures in the marly and limy Cretaceous, with different resistivities; c) Camargue (thick series of conductive sediments); d) Beziers Basin (highly complicated structures in the Mesozoic, widely blanketed by conductive Miocene).It may be assumed that electrical methods can yield valuable information enabling one to define the rugged subsurface topography of resistive strata burried under a reasonably thick cover of conductive sediments especially when a part of the lower formation outcrops even if the part exposed be small. Faults may be delineated and much, more information is obtainable than can be expected from gravity meter survey at a price not very much higher.
