Geodynamic evolution and petrogenesis of the neoarchaean Francistown granite-greenstone complex in NE Botswana, SW margin of the Zimbabwe craton

The Archaean Francistown Granite-Greenstone Complex in NE Botswana is an integral part of the southwestern margin of the Zimbabwe Craton. It includes a suite of geochemically diverse Neoarchaean granitoids and mafic dominated-supracrustal assemblages. All the supracrustal rocks and mafic intrusions have undergone greenschist to lower amphibolite facies metamorphism, but most mafic intrusions have preserved original igneous textures. The Francistown Granite Greenstone Complex likely represents an arc complex that developed along an active continental margin in the Neoarchaean. This thesis presents new geological, geochemical and geochronological data with which to evaluate the crustal evolution of the NE Botswana, and with which to formulate a geodynamic model for better understanding of the Archaean crustal growth flanking the southwestern margin of the Zimbabwe Craton
