This chapter discusses that the present-day shape of both Murzuq and Kufra basins reflects a Variscan and Mesozoic overprint on an older structural relief. The present work is designed to study the sedimentary cover of part of the Kufra Basin by means of potential field analyses and modeling. The basin has been.

The basin data is derived from a lower resolution grid which has been upsampled using GMT. This could have introduced an accuracy which is beyond the original data resolution. The basin cross bwsin is automatically generated using the available crustal structure data sets. Sometimes the data labels are not plotted correctly, depending on the length of the section. The location of the profile is indicated in all maps as dashed-dotted thin black line.
For the endpoints of the profile, the two points of a given polygon located farthest away from each other were computed. The dynamic topography history for the basin is derived by tracking the basin centroid.
The paleo-location for this point is computed using the EarthByte plate kinematic framework rotating bassin position back in time. The density anomalies are then advected back in time to compute mantle flow with plate motions superimposed using the EarthByte plate rotation framework as surface boundary conditions.

The dynamic topography is then derived from the computed density distribution using a free upper boundary. For details regarding the methodology see the following papers: Large-scale lithospheric stress field and topography induced by global mantle circulation. Effects of latent heat release at phase boundaries on flow in the Earth’s mantle, phase boundary topography and dynamic topography at the Earth’s surface.
