3. Magmatism in the Cenozoic Ethiopian rift zone : the case against the Afar plume hypothesis
Abstract : Volcanism and rifting in the Afro-Arabian, i.e. Red Sea - Gulf of Aden - Ethiopian, region have often been attributed to a Tertiary plume centered on Afar, at the junction of the three rifts. READ MORE

5. U-Pb baddeleyite geochronology of Precambrian mafic dyke swarms and complexes in southern Africa - regional scale extensional events and the origin of the Bushveld Complex
Abstract : Dolerite dykes are formed when iron- and magnesium-rich (mafic) mantle-derived magmas ascend through the lithosphere (upper part of the mantle) and crystallize as ‘hydro-fractures’ within the crust. Dykes may exist in great numbers to form dyke swarms (linear or radiating), which can be linked to time periods of continental break-up, or attempted break-up events, associated with voluminous volcanism.
