In an effort to improve the calibration of the Late Triassic time scale, two stratigraphic successions in Italy were investigated for magnetostratigraphy: the Pignola-2 (Southern Apennines) and the Dibona (Dolomites) sections. These sections reveal a sequence of biostratigraphically calibrated (conodonts and palynomorphs) magnetic polarity zones encompassing the Julian/Tuvalian boundary (Carnian). A total of 63 samples have been collected from the Pignola-2 section that helped defining 3 magnetozones. These data are constrained by a published radiometric U/Pb age of 230.91 0.33 Ma from the Aglianico ash-bed (Furin et al. 2006). From the Dibona section, 81 samples have been collected, revealing 2 magnetozones in the Heiligkreuz Fm. (lower part of the succession) and 2 magnetozones in the Travenanzes Fm. (upper part). The Dibona section provided only few high-quality paleomagnetic data in spite of the sampling effort, so we considered only the Pignola-2 section as suitable for the correlation with other Carnian sections from the literature, in order to define the magnetostratigraphy around the Julian/Tuvalian boundary in the Tethys realm. The correlation between the Pignola-2 and the Newark Astrochronological Polarity Time Scale (APTS) provides independent insights on the age of the base of the Newark basin APTS. We found that the U-Pb zircon-dated Pignola-2 level, magnetostratigraphically projected on the Newark APTS, falls within Chrons E5–E4 at around 231 Ma, in agreement with the (extrapolated) astrochronological ages of the Newark APTS.

More about this publication?
  • Newsletters on Stratigraphy is an international, peer-reviewed journal with a focus on stratigraphic issues that are relevant for a broad geoscientific community. Papers published in Newsletters on Stratigraphy use (and ideally integrate) stratigraphic methodologies from a wide field of disciplines, including (but not limited to) biostratigraphy, chronostratigraphy, chemostratigraphy, and magnetostratigraphy.

    The results have implications for paleogeographic reconstructions, paleoceanography, paleoclimate, biotic evolution, basin development, or regional and supraregional correlation.

    Papers published in Newsletters on Stratigraphy comprise original research articles, background information on ongoing work of e.g., the International Stratigraphic Commission (ICS) and the International Subcommission on Stratigraphic Classification (ISSC), and review articles. There are no page charges for the publication of regular papers.
