An integrated geoelectrical survey has been conducted at the Wadi Marsad area, south of Jordan, to map the dominant structural features associated with the Arabian-African plate movements. The area is known to be tectonically affected by the epeirogenic movements of the Arabian shield which originated several major and minor structural features. Fifty-four vertical electrical soundings (VES) using Schlumberger configuration and nine induced polarization (IP) profiles (both resistivity and metal factor parameters were determined) were carried out in the investigated area. The integrated use of IP and VES surveys has proved to be efficient in mapping the lateral and vertical extensions of a major graben structure existing in the investigated area.
