Abstract

Strontium isotope profiles are provided from the Austrian Salzkammergut and southwest England, two of the best available marine sections across the Triassic-Jurassic boundary. The results in the English section have been affected by diagenesis, but the Austrian results are excellent and demonstrate that, in favorable circumstances, trustworthy Sr isotope results can be obtained from pure or nearly pure limestones, and oxygen isotope data provide the best means of obtaining an independent check. Although the Triassic-Jurassic boundary was marked by significant sea-level changes, this is not reflected in the Sr isotope results, which show no change across the boundary, in contrast to what has been claimed for the Cretaceous-Tertiary and Permian-Triassic boundaries.
