Africa

Africa is the most stable continent with respect to its movement during the late plate tectonics.
The nucleus of the continents is based on the amalgamation of different cratons, which are
associated with large, deep basins. Although there has been long-standing scientific efforts towards
the structure of the crust and mantle underneath Africa, ground-based observations are still sparse in
all but a few regions.
Martinec and Fullea (2015) discussed the sensitivity of the GOCE gravity model to the density
stratification of the uppermost part of the Earth's crust and demonstrated that a priori geological
knowledge of the density stratification of the sedimentary rocks that form the Congo basin can largely
be improved in both horizontal and vertical directions. Also for the Bangui magnetic anomaly to the
north of the Congo basin a mantle contribution has been proposed and we will re-evaluate these
models and ideas with the new satellite data and link the results closely to global and regional velocity
and conductivity models. In addition, the southern portion of Africa exhibits high topography for which
dynamic topography has been proposed as an origin and Africa is as well located over the LLSVP at the 
core-mantle boundary, which makes it an ideal case to study the link between the deep Earth and the surface.
