Abstract

Summary

The Permian and Triassic floodplain deposits in the SE part of the Germanic Basin reveal significant climatic oscillations driven by global warming and the onset of supermonsoonal circulation. A detailed analysis of continental deposits, including palaeosols and palustrine horizons, allowed us to extract climatic signals and assess their impact on sedimentary patterns. The Permian-Triassic boundary is marked by a shift from arid floodplains with calcisols to humid conditions fostering inceptisols, accompanied by changes in palynological and detrital compositions. Early Triassic deposits exhibit fluvial instability, transitioning to more stable floodplain systems with evolving soil profiles, indicating gradual climatic stabilisation. The Middle Triassic is characterised by marine sedimentation, while the Late Triassic marks a return to continental conditions with alternating arid and humid intervals, including pluvial events during the Carnian and Norian. The study highlights the value of palaeosols and palustrine horizons as climatic markers and their utility in basin analysis for oil and gas exploration, as well as CCS and hydrogen storage well planning.
