Overview
Interests
Wolfgang's research deals with petrological and geochemical processes in mafic-ultramafic igneous systems that contribute to our understanding of continental magmatism, mantle evolution, plate tectonics and the formation of magmatic ore deposits including PGE, Ni-Cu, Cr, and V-Ti-Fe deposits. He is also interested in planetary evolution, meteorites and impact melt sheets, and in finding new approaches to make exploration and mining more sustainable, particularly in Africa.

Teaching
My teaching interests span a relatively wide field. Throughout my career, I have been heavily involved in undergraduate and postgraduate teaching of igneous petrology, geochemistry, economic geology, mineralogy, and metamorphic petrology. I have co-led the annual mapping camp of the University of Pretoria (UP) Geology Department between 1998-2003, and organized and led several international field trips (South Africa and Cyprus several times, Kola peninsula).
Curriculum development has been one of my key responsibilities as a teacher during the last decade. In order to respond to the minerals boom in Scandinavia which has become the exploration and mining powerhouse of Europe, requiring an increasing number of geologists, I designed a new International Master Course that started in September 2012 at the Geology Department at Oulu University.
In addition to tertiary education, I have also been keenly interested in pre-university geological teaching and education. Between 1998-2001, I have participated in the University of Pretoria's geological education programme for final-year pupils at Pretoria secondary schools. South Africa's education system is in transformation and the programme is particularly aimed to enhance the scientific background of students from formerly disadvantaged backgrounds, a challenging but inspiring task.
Present Courses
3rd year Ores and Ore Genesis
3rd year Cyprus and North Wales excursions
2nd year Cornwall field excursion
2nd year Exploration Case Studies
Wolfgang's main research interests presently are (i) Mineralized magmatic systems in southern and central Africa (e.g. the PGE mineralized Bushveld Complex, Okiep, Ni deposits in the Tati greenstone belt and at Selebi Phikwe in Botswana, the Kunene gabbro-anorthosite Complex of Namibia/Angola, the Tete gabbro-anorthosite Complex of Mozambique, the Ni mineralized Kabanga-Kapalagulu-Musongati intrusions of Tanzania and Burundi, the Monts de Cristal intrusion of Gabon), Finland (Kevitsa, Penikat), Canada (Bell River and Highbank Lake Complexes), Brazil (Caraiba, Mirabela), Australia (Giles Complex, Hart dolerite), as well as Archean basalts and komatiites in the Pilbara, Karelian, and Kaapvaal cratons. (ii) PGE concentrations of the Earth's upper mantle, based on southern African and Finnish mantle xenoliths, peridotite mantle massifs (Outokumpu and Jormua, Finland), and SCLM derived magmas (GroupII kimberlites, alkali basalts), and implications for processes of partial melting and crystallization/ metasomatism in the upper mantle. (iii) The Morokweng meteorite and impact melt sheet.
Wolfgang studied geology at the Ludwig Maximilians University of Munich, Germany (MSc on South African BIFs, 1987) and Rhodes University, South Africa (PhD on the Bushveld Complex, 1992). He taught igneous petrology and economic geology at the Universities of Pretoria (South Africa), Chicoutimi (Canada), UWA (Australia), and Oulu (Finland). He joined Cardiff University in 2013.

Impact
Metals such as copper, nickel and platinum-group elements (PGE) are essential in confronting some of the world’s greatest societal and industrial challenges. However, long-term resource depletion and decreasing explorable and mineable terrain threaten their availability and security of supply. Cardiff University (CU) research has led to a greater understanding of the formation of magmatic ore deposits – formed from the crystallisation and solidification of molten magma or lava and lie within igneous rocks – and the generation of new exploration strategies and targets. This work has been conducted with partners across the globe, including Ivanplats in South Africa, Northern Shield in Canada, the Geological Survey of Western Australia and the Geological Survey of Finland. The research has directly resulted in the discovery of several large deposits and in more efficient exploration and mining, with important cost savings and reduced social and environmental impact.
