The greenstone belts of Zimbabwe : Wilson, J. F
The present configuration of the greenstone belts is explained. Three ages of granite-greenstone terrain can be recognized within the Zimbabwe Archean Craton. The oldest greenstone belt remnants constitute the volcano-sedimentary Sebakwian group dated at c. 3.5 Ga minimum on the evidence from various granites and gneisses.
