Arguments géophysiques et géologiques en faveur de manifestations volcaniques récentes dans la région du lac Faguibine (Mali)

The interpretation of gravimetric data obtained in Faguibine lake area (Mali) was compared with observations characteristic, of recent tectonic activity, current earthquakes and new results on the volcanic origin of Daoumites. We present a new gravity model which corresponds to a 100 ktn wide, superficial volcanic body 2 or 3 km below the surjiace.
