This work is a understanding of the collision geodynamic context in Katonto (25 km )in the North-West of Kolwezi. Here are presented a detailed petrographic study of the Muva group , the style tectonic and tectonic zonality on a scale of Kolwezi advanced as well as a tectonic interpretation of study area. This career was highlighted the abnormal compressionnal fault contact which separated Kundelungu from the subjacent kibarien as well as the presence of two units (sequences). The kibarian stratiform sedimentary laid out in with iron sulphides, of copper and of cobalt traces . The tectonic constraints related to compressionnal were less has less significant from the west to the east. The reactivation of faults of subjacent kibarien formation would have implemented a tectonic style in the katanguian supergroup which surmounts it. The tectonic style for the area of Kolwezi is distinguished from the other sectors only in the extent of the extrusif phenomenon.

Abstract: (french)
Ce travail est une contribution à la compréhension du contexte géodynamique de collision à Katonto à 25 km au nord-ouest de Kolwezi. Nous présentons une étude pétrographique détaillée du groupe de Muva, le style tectonique et zonalité tectonique à l’échelle de l’avancée de Kolwezi ainsi qu’une interprétation tectonique du secteur d’étude. Cette carrière a été mise en évidence le contact anormal qui sépare le Kundelungu du kibarien sous-jacent ainsi que la présence de deux unités (séquences) sédimentaires du kibarien comportant des sulfures de fer, avec traces du cuivre et de cobalt, disposées de manière stratiforme. Les contraintes tectoniques liées à la compression étaient de moins a moins importante de l’ouest à l’est. La réactivation de failles du kibarien sous-jacent aurait implémentée un style tectonique au supergroupe katanguien qui le surmonte. Le style tectonique pour la région de Kolwezi se distingue des autres secteurs uniquement dans l’ampleur du phénomène extrusif. L’avancée de Kolwezi aurait été mise en place par un mécanisme extrusif extravase subsurface.
