Anton Le Roex

Emeritus Professor

Research

My research interests lie in understanding the geochemical composition and evolution of mafic igneous rocks, their differentiates and their mantle source regions. The role of mantle plumes in the generation of intra-plate magmatism, both within oceanic and continental regions, the origin of their geochemical characteristics and their interaction with surrounding asthenospheric and overlying lithospheric mantle are fundamental foci of my research interests. Primary geographical areas of interest include the Southern Ocean, southern Africa, Madagascar and the mantle underlying Gondwanaland.
