Atlas salt-related rifting

Forewords

Our studies in the High Atlas of Morocco started in 2011 within a collaboration research project between former Statoil (Equinor), Bordeaux Univ. and GDL-GEO3BCN-CSIC.  The main objective was the study of thick Jurassic carbonate platforms and their links to syn-rift faults but ending on the re-discovery of a large Jurassic salt tectonic province. 

In addition, recent studies on the Tellian and Atlas fold belts in Tunisia are also presented in this section.
