The proterozoic supercontinent rodinia : paleomagnetically derived reconstructions for 1100 to 800 ma
TL;DR: In this article, the apparent polar wander paths (APWPs) for the interval 1100-800 Ma have been constructed for the Laurentia, Baltica, Sao Francisco, Congo and Kalahari cratons.
Journal ArticleDOI
Pan-African rifting and orogenesis in southern to equatorial Africa and eastern Brazil
TL;DR: In this article, the authors apply the rifting model describing the formation and further evolution of rift structures in the continental crust leads to the conclusion that the West Congolian belt, as traditionally described, is incomplete and has to be supplemented by the Mayumbian belt and a rift structure situated farther to the west.
Journal ArticleDOI
Proterozoic geochronology and tectonic evolution of southern Africa
TL;DR: The Namaqua-Natal Belt defines a major convergent plate boundary active at this time along the southern margin of the Archaean Kaapvaal Craton, and the western part of this belt is inferred to link with a largely buried, NE-trending orogen present in the Kalahari region as mentioned in this paper.

The western arm of the Lufilian Arc in NW Zambia and its potential for copper mineralization
TL;DR: In this paper, a minimum age for the underlying Roan Group of the Kundelungu Group is provided, between ∼765 and ∼735 Ma, which is the earliest known date for the Roan group in the world.

Towards a new understanding of the Neoproterozoic-early palæozoic Lufilian and northern Zambezi belts in Zambia and the Democratic Republic of Congo

TL;DR: In this article, basic knowledge and assumptions are reviewed and existing models critically assessed, including recognition of standard lithostratigraphies of the Katanga supergroup comprising the Roan, Mwashia, Lower and Upper Kudelungu Groups in the Copperbelt and Katanga, a lower limit for the onset of deposition at about 880 Ma, and a major orogenetic event involving northeast directed thrusting (Lufilian Orogeny) at 560-550 Ma.

Evidence for late Precambrian plate tectonics in West Africa
R. Black,Renaud Caby,A. Moussine-Pouchkine,R. Bayer,J. M. Bertrand,A. M. Boullier,J. Fabre,A. Lesquer +7 more
TL;DR: In the Gourma and Iforas regions (Mali) rifting occurred around 800-850 Myr ago along the eastern margin of the West African craton with a triple point in Mali, interpreted as an aulacogen as discussed by the authors, the suture is marked by a string of positive gravity anomalies corresponding to the emplacement of ultrabasic and basic rocks including perhaps ophiolites.

Suture zone complexities: A review
TL;DR: Suture zones, marking the sites of obliteration of oceanic lithosphere by subduction and the consequent intracontinental welding of continental masses, are rarely simple, single, easily recognizable lines as discussed by the authors.
Journal ArticleDOI
The evolution of the Pan African crystalline basement in NE Africa and Arabia
TL;DR: In this article, field and petrographic evidence indicate an intra-oceanic island arc environment for the mainly volcanoclastic sediments and geochemical data suggest that magmatic products were generated at or above easterly inclined Benioff zones.
Journal ArticleDOI
Late Precambrian ophiolitic mélange in the eastern desert of Egypt
TL;DR: The interpretation of the late Precambrian (Pan-African) fold belts in Africa is controversial as mentioned in this paper, and it is uncertain whether, like Phanerozoic fold belts, they were formed by plate tectonic processes or whether they are ensialic and unrelated to subduction of oceanic crust.
