A 330-metre core drilled through the marine Permian/Triassic boundary in the Carnic Alps of Austria allows closely correlated studies of geochemistry, petrography and palaeontology across the boundary. The isotope shifts and metal concentrations are extended, multiple and complex, and do not resemble those seen at the Cretaceous/Tertiary boundary. Both the carbon isotope shifts and the chemical events (including an indium anomaly) may have causes related to a major regression of the sea. 
Carbon and Sulfur Isotope Stratigraphy of the Permian and Adjacent Intervals
The Permian was a most unusual period in geologic history. It was marked by repeated largescale climate changes, major extinction events, abrupt and extensive volcanic activity (the Siberian traps),Expand

TLDR
The symmetry in lithostratigraphy and redox condition of the boundary sections suggest that the superocean Panthalassa became totally stratified for nearly 20 million years across the Permo-Triassic boundary. Expand

Geochemistry of the end-Permian extinction event in Austria and Italy: No evidence for an extraterrestrial component
The end-Permian mass extinction (251 Ma) was the largest in Earth's history, and the great extent of biospheric perturbation is recorded as dramatic shifts in carbon isotope ratios of sedimentaryExpand

Abstract The end Permian marks the greatest extinction in the geological record, but there is no consensus on whether it was caused by terrestrial or extraterrestrial factors. Platinum group elementsExpand
