Research Interests

Igneous petrogenesis, especially of granitic rocks

High-grade metamorphism and crustal melting

Experimental petrology

Current Projects

The Configurations and Origins of Chemical Structure in Felsic Magmas
Petrological, geochemical and rock magnetic techniques are being used to map the internal compositional structure of many plutonic and volcanic masses (in South Africa and Australia) and to investigate the mechanisms by which granitic magmas attain their compositional heterogeneity and Earth’s continental crust becomes compositionally differentiated. Stevens and Buick and Kisters (Stellenbosch), Birch (Museum Victoria), Maas (Melbourne University), Nicholls (Monash), Regmi (Namibia), Waight (Danish Geological Survey), Phillips (Phillipsgold) and Jung (Hamburg) are the main collaborators.

There are numerous sub-projects within this overall theme, including a major study of the giant Donkerhuk batholith in Namibia, funded by a major grant (to Clemens, Kisters and Buick) from the South African NRF.
