A bstract The main features of the gravimetric map of the Gharb can be related to the shape of the basement, covered by cretaceous and miocene layers, with a total maximum thickness of 13,000 feet. For the interpretation of local features, in the northern part of the basin, first a regional anomaly has been drawn, then the map of the first derivative has been established. Both maps are compared with geological maps and seismic and electrical surveys. The results are the following: As for method, the advantages and limitations of both processes are outlined. As for geological interpretation, it is suggested that most of the local features of the gravimetric map are due to the preriffan tectonics.
