Abstract

Available land-based gravity data and geopotential data model infills are used, together with a Digital<br>Elevation Model, to produce a Bouguer gravity anomaly map of Africa. The pattern of Bouguer gravity<br>anomalies is an intricate interference of contributions reflecting density heterogeneities on a wide spectrum of<br>scales. These contributions relate to the various structures and underlying geodynamic processes within the<br>African lithosphere and underlyting mantle. A selective normalization process is used to isolate some of these<br>contributions. The end product is a gravity anomaly map of Africa that can be directly correlated with geology<br>and interpreted in terms of crustal structures. We will present the results of this work.
