The crustal architecture of Archaean terranes in Northeastern Botswana
New and published geological, geochemical and U-Pb zircon age data are combined to model the architecture and evolution of the Archaean crust in north-eastern Botswana. Four distinct crustal terranes are identified. The Francistown granite-greenstone terrane at the south-western margin of the Zimbabwe craton, is interpreted as a continental-margin arc complex (the Francistown Arc Complex) that developed between ∼2710 and ∼2647Ma. Outboard of this arc complex, and separated from it by the Shashe...[Show more]
