Mise en évidence d’une Triade Glaciaire néoprotérozoique dans le secteur de Landiéné-Bandafassi, Bassin de Madina Kouta (Kédougou, Sénégal, Afrique de l’Ouest)

A groundbreaking study identifies the first occurrence of the Neoproterozoic 'Glacial Triad'—comprising tillite, dolomite, and cherts—in the Landiéné-Bandafassi sector of Senegal's Madina Kouta Basin. This discovery, previously unknown in this region, provides critical stratigraphic markers for West African sedimentary basins, offering insights into ancient glacial deposits. The research involved detailed lithostratigraphic and petrographic analyses across ten sections, correlating findings with the well-studied Walidiala valley. Notably, the absence of Supergroup 1 and the continental nature of glacial formations in this sector were also highlighted, challenging existing models of depositional environments.
