The geodynamic evolution of the Southern
Tethyan Margin of Tunisia is investigated using geophysical
studies. Analysis of gravity and seismic reflection data
in the Maghrebian domain and Southern Tunisia reveals the
geodynamic role played by the North Saharan Flexure
(NSF) in the evolution of the Southern Tethyan Margin.
The Saharan Atlas Mountains (Atlasic Basin) and the
African Craton (Telemzan High) are separated by the NSF
which is a regional-scale feature that may represent a
