The Kisanga iron caps in Southern Shaba (Zaïre), situated in the Kakontwe Limestone, result from the filling of an Upper Proterozoïc paléokarst. These ancient karstic traces have been related to a local and temporary emergence in the Likasi district caused by the Kipushi rift structuration during the early Lower Kundelungu.Les gisements de fer de Kisanga (Shaba méridional, Zaïre), sont situés dans le Calcaire de Kakontwe (Kundelungu inférieur) et correspondent au remplissage d'un paléokarst du Protérozoïque supérieur. Ces anciennes traces karstiques ont été rapportées à une émersion locale et temporaire de la région de Likasi causée par la structuration du rift de Kipushi au début du Kundelungu inférieur.Buffard Roland.
