摘要: Abstract The Mwembeshi Fault Zone in Zambia separates the Lufilian Arc and Zambezi Belt with divergent tectonic structures, marks suture of colliding cratons. is correlated Okahandja Lineament intracontinental branch Damaran Orogen Namibia. Crustal shortening across larger at its western extremity, where large-scale thrust sheets are present Kolwezi area. crustal block underlying largely fault bounded. It rotated clockwise as blocked collision zone Congo Kalahari cratons was subject to sinistral strike-slip translations late deformation phases Pan-African orogeny. postulated that margin formed by a transcurrent which probably evolved from transform separating Lufilian-Zambezi sections during spreading phase mobile traverses southern Africa.
