Résumé:

The Neoproterozoic strata of the Taoudeni Basin (West African Craton) display a single glaciogenic deposit, late Cryogenian in age, and included within a stratigraphic-marker ‘Triad’ of tillite, carbonate, and bedded chert. This work is focused on the analysis of the sedimentary architecture and episodic carbonate productivity related to its transgressive deglaciation recorded in the Atar cliffs of Adrar, Mauritania. It offers a joint chemo-, event-, and sequence-stratigraphic analysis that allows us to control problems of stratigraphic completeness and time resolution, necessary for regional and worldwide stratigraphic correlation.
