TL;DR: A 330-metre core from the marine Permian/Triassic boundary in the Carnic Alps of Austria allows closely correlated studies of geochemistry, petrography and palaeontology across the boundary as mentioned in this paper.

TL;DR: A systematic search for impact indicators was conducted on a core of Late Jurassic-Early Cretaceous sedimentary strata from the vicinity of the proposed Mjolnir impact structure, Barents Sea as discussed by the authors.

TL;DR: A strong δ-sup 13C anomaly coincides with a weak Ir anomaly at the Frasnian/Famennian (F/F) boundary exposed at Xiangtian, Guangxi, south China as discussed by the authors.

TL;DR: In this article, the authors analyzed samples from four Ordovician-Silurian boundary sections of graptolitic shales and mudstones in the Yangtze Basin (Yangtze Platform) on the South China Plate, and chemically analyzed the abundances of about 40 common and trace elements and iridium.

TL;DR: In this paper, measurements of elemental abundances by neutron activation methods across the Cenomanian-Turonian extinction interval in samples collected from 16 sites in the Western Interior Basin of North America from 12 widely separated locations around the globe, including six ODP/DSDP sites, are reported.
