Stable Isotope Event Markers Near the Permo-Triassic Boundary in the Karavanke Mountains (Slovenia)

Abstract

Stable isotope analyses of carbonates and organic matter from thePermo-Triassic boundary section in the Karavanke Mountains, Slovenia,indicate a further example of the Òlight carbonÓ event across theboundary. In this section the changes in carbon isotope values were adirect result of the culmination of the marine regression and associatedevents at the end of the Permian, which caused a drop in primaryproductivity, as well as related local environmental changes, with noevidence of any considerable diagenetic overprint.
