The present thematic issue is dedicated to the West African Craton (WAC) and its margins (Fig. 1). The project was launched during the "First West African Craton and Margins International Workshop", which took place in Dakhla (Morocco) on 24-29^th April 2017. The aim of this meeting was to confront the results of different teams working on various topics, mainly in the northwestern parts of the WAC and their Pan-African to Present margins. The workshop, organized basically by one of us (O. S.) and the University Hassan II of Casablanca, met with great success. Indeed, the Moroccan part of the WAC and the adjoining Oulad Dlim massif (aka Adrar Souttouf) are under the spotlights. Mapping programs, metallogenic prospection, and academic research backed on petrological and geochronological analyses have been intensely focused on the formerly Spanish Rio de Oro, which became Moroccan in 1975. These recent (and ongoing) studies have greatly improved our understanding of the geological structure and tectonic-stratigraphic evolution of the area.
