Altermann, Wladyslaw: -
Professor Wladyslaw Altermann is a regional geologist with expertise in Precambrian sedimentary systems, carbonate rocks, early life evolution, and more recently, CO₂ sequestration in South Africa. Originally from Poland, he earned his MSc and PhD (Dr. rer. nat.) at the Free University of Berlin (West), focusing on Permo-Carboniferous rocks of Thailand and Malaysia. He also worked for the German Federal Institute for Geosciences and Natural Resources (BGR) in Hannover and in Peru.
In 1988, Prof. Altermann moved to South Africa, which became his third home. After a postdoctoral fellowship at the University of Stellenbosch, he returned to Germany to join LMU Munich, where he completed his second doctorate (Dr. habil.) in 1998, studying Archean carbonates, stromatolites, BIFs, and the western Kaapvaal Craton's structural geology.
Prof. Altermann held postdoctoral positions at UCLA (USA), CBM-CNRS Orléans (France), and the University of Western Australia (Perth). He later became Associate Professor at LMU Munich, where he served as interim chair for several professorial positions and served as Honorary Professor at Shandong University of Technology (China) from 2003 to 2005. In 2009, he returned permanently to South Africa, joining the University of Pretoria as the Kumba-Exxaro Chair in Geodynamics of Mineral Deposits (mining industry supported Chair) and later becoming Head of the Department of Geology.
Throughout his career, Prof. Altermann has been deeply involved in the scientific community, serving on national committees and editorial boards for international journals and as editor of books and special volumes. He was a Vice-President of the Geological Society of Africa and Chairman of the South African Committee for Stratigraphy. He retired from UP in 2019 and has since been working as a freelance geological consultant in Pretoria.
Ernst, Richard E.: - Dr Richard Ernst is Scientist in Residence at Carleton University, Ottawa, Canada. His career has been focussed on Large Igneous Provinces (LIPs) with nearly 300 refereed publications on all aspects of LIPs: including their dramatic flood basalts, 'plumbing system' of mafic/ultramafic dykes, sills and layered intrusions, and association with carbonatites, kimberlites and silicic magmatism; links to supercontinent breakup, catastrophic environmental/climate change including mass extinction events, mineral, metal and hydrocarbon resource exploration, and planetary analogues; and characterizing the role of mantle plumes in their origin. He is the author of "Large Igneous Provinces", Cambridge University Press (2014), a leader of the LIPs Commission of IAVCEI (since 2003), leader of the LIPs and Resource Exploration Program ("LIPs Industry Consortium", since 2010), leader of the International Venus Research Group (IVRG) (since 2021). He received the 2022 Career Achievement Award of the Volcanology and Igneous Petrology Division (VIP) of the Geological Association of Canada, and was elected a Fellow of the Geological Society of America (2024).
Heubeck, Christoph: - "Prof. Heubeck is a regional "soft-rock" geologist. Originally from Germany, he completed an MSc at the University of Texas at Austin on Tertiary basins on the Caribbean island of Hispaniola, followed by a PhD from Stanford University on the Barberton Greenstone Belt of South Africa and Eswatini. He worked for six years as an explorationist and development geologist for Amoco and BP in the US and Canada before joining the Free University Berlin as a faculty member. There, he conducted studies on the Ediacaran-Cambrian boundary in Kazakhstan and China and on Andean Tertiary basins in South America before taking up his interest in the Barberton Greenstone Belt again. In 2014, he moved to the FSU Jena where he holds the chair of General and Historical Geology. Most of his studies are field-based, range from the grain- to the basin-scale, and use - in collaboration with experts - whatever methods are necessary to address the problem at hand."
