Summary

The Permian-Triassic Boundary (PTB) is known for the severest mass extinction in earth history. In recent time, the driving environmental perturbation have been increasingly considered, however, mostly for marine systems. We shift the focus to clastic, continental systems. Within two PhD projects, we carry out case studies in the Germanic Basin and in Ethiopia. So far, we published a temporary resolved sediment budget for the entire Central European Basin System (CEBS) based on the South Permian Basin Atlas. Our results show a strong rise in sediment supply at the PTB which support the hypothesis of strong perturbations of continental environments. Currently, we study the Permian-Triassic transition petrographically and geochemically in wells of SW Germany and Central Germany in detail. In Ethiopia, we investigate the Permian to Jurassic Karoo succession of the Blue Nile River Basin using a multi-proxy approach. This involves single grain analysis and U-Pb dating of detrital zircons.
