Abstract
Gravity data were analysed in the Nebeur area to better understand the organization of its underlying structures. Analysis of the gravity data included the computation of a complete Bouguer anomaly, upward continuations, as well as residual and derivative maps.Comparison of gravity maps, geological and structural maps allows the identification of major structural directions and trends of the study area. It confirms some structural elements gathered from outcrops and defines new ones. In particular, the Oued Tessa – Bled el Ghorfa area that is characterized by a negative gravity anomaly, corresponds to a collapsed structure limited by two NW–SE fault systems. This result extends to north the graben zone that is described from outcrops.
