Abstract
The basement–cover contacts in the Jukskei River shear zone were studied to investigate their geological significance and relationship to regional deformation and alteration events. To address this, the study used a multi-disciplinary approach that integrated structural, petrographic, geochemical (major and trace elements), isotopic (carbon isotopes) and Raman spectroscopy data. The basement granodiorites and tonalites in this study are part of the Johannesburg Dome of the Archean Kaapvaal Craton. Cover sequences in this study are the Black Reef Formation (Transvaal Supergroup) and the Witwatersrand Supergroup. The Black Reef Formation sits nonconformably on weathered granodiorite, whereas the basement– Witwatersrand Supergroup contact is tectonic in nature...
