Rampino, M.R., A. Prokoph, and A. Adler, 2000: Tempo of the end-Permian event: High-resolution cyclostratigraphy at the Permian-Triassic boundary. Geology, 28, no. 7, 643-646, doi:10.1130/0091-7613(2000)28<643:TOTEEH>2.0.CO;2.

The Permian-Triassic (P-T) boundary is marked by the most severe mass extinction in the geologic record. High-resolution cyclostratigraphy on a 104 yr scale across the P-T boundary in a core from the Carnic Alps (Austria) revealed significant cycles in the ratio ∼40:10:4.7:2.3 m, identified with Milankovitch cycles of ∼412:100:40:20 k.y. (eccentricity 1 and 2, obliquity, and precession). Wavelet analysis indicates continuity of deposition across the boundary, with an average accumulation rate of ∼10 cm/k.y. The dramatic faunal changes at the P-T boundary can be constrained within an interval of <60 k.y. (possibly <8 k.y.), with the accompanying sharp negative global carbon-isotope shift within <30 k.y., suggesting a catastrophic cause.
