摘要:Compilation of the recent literature from the Southern Alps and adjacent area confirms the geochemicalvariations of unusual amplitudes during the Permian-Triassic boundary interval (PTBI). A great attentionhas been given to the negative δ13C anomaly within the Tesero Member close to the Permian-Triassicboundary. Very detailed geochemical works have been done on the scientific Gartnerkofel core (Gk-1) andon the Slovenian sections. Major minor and rare earth elements (REE) data are reported and show a markedenrichment in alkaline metals and REE of some levels of the boundary interval. But recent studies show thatthe low Iridium anomalies and the Osmium and Helium isotopes anomalies lack the characteristics of a largeextraterrestrial impact.
