PermTriasGrenzprofil
PermTriasGrenzprofil is a geological term used to describe the boundary profile at the Permian–Triassic boundary, the transition between the Permian and Triassic periods. The concept encompasses the integrated stratigraphic signal observed in outcrops and drill cores, including lithology, fossil content, and geochemical markers, which together help to correlate sections across regions.
A typical PermTriasGrenzprofil combines multiple lines of evidence. Lithologically, it often shows a noticeable shift in
