鈥�Axel Hofmann holds a doctorate from the 欧美福利100000 of Mainz in Germany and has worked as a researcher and lecturer at the 欧美福利100000 of Zimbabwe, Wits 欧美福利100000 and the 欧美福利100000 of KwaZulu-Natal. His main interest and expertise is centred on the Archaean geological record of southern Africa. His research emphasizes the importance of field work and the usage of an integrated suite of petrological, structural, and geochemical tools in order to decipher the geological history of Archaean volcano-sedimentary successions. Research Interests Archaean surface processes, evolution of greenstone belts, geochemistry of sedimentary rocks, sediment-hosted ore deposits, habitat of early life Current projects - Early Earth Life and Mineral Systems 鈥� exploring the relationship between surface processes, evolution and habitat of life and the formation of mineral deposits on the early Earth
- Sedimentology, basin evolution and gold/uranium mineralization of the Pongola and Witwatersrand supergroups
- Peering into the Cradle of Life 鈥� scientific drilling in the Barberton greenstone belt
- Various projects on the Precambrian geology of Zimbabwe, the Francevillian Basin of Gabon, and the Singhbhum Craton of India
