“…In the Eiberg basin two sections have been investigated: Eiberg and Kuhjoch. The Eiberg section covers the middle and upper part of the Rhaetian and was the subject of many stratigraphic studies (e.g., Golebiowski, 1991;Clemence et al, 2010;Mette et al, 2012;Korte et al, 2017). The Kuhjoch section was choosen as it represents the Hettangian GSSP (Triassic-Jurassic boundary) (Hillebrandt et al, 2013).…”

“…The Austrian Late Triassic marine sedimentary successions are biostratigraphically the most complete and lithologically suitable for cyclostratigraphy. We analyzed four key sections encompassing the whole Rhaetian: (1) the Steinbergkogel section proposed as the Rhaetian GSSP (Krystyn et al, 2007a, b;Krystyn, 2010;Hüsing et al, 2011), (2) the Zlambach section which covers most of the lower and middle part of the Rhaetian (Matzner, 1986;Krystyn, 1991;Richoz and Krystyn, 2015), (3) the Eiberg section, covering the upper part of the Rhaetian, which was the subject of numerous stratigraphic and micropaleontologic studies (e.g., Kuss, 1983;Golebiowski, 1991;Clemence et al, 2010;Mette et al, 2012;Korte et al, 2017), and (4) the Kuhjoch section, Hettangian GSSP (Triassic-Jurassic boundary) (Kürschner et al, 2007;Ruhl et al, 2010b;Richoz et al, 2012b;Hillebrandt et al, 2013). Magnetic susceptibility (MS) was used as an indicator of climate change for cyclostratigraphic analysis.…”

“…Several studies have suggested a minor carbon cycle perturbation and associated negative CIE to precede the end-Triassic mass extinction (sometimes referred to as the precursor CIE) [Deenen et al, 2011;Ruhl & Kürschner, 2011;Lindström et al, 2012;Dal Corso et al, 2014;Davies et al, 2017]. The Upper Triassic sequences in the Eiberg Basin have only been studied extensively in the Eiberg quarry [Korte et al, 2017]. Based on this succession, an even earlier carbon cycle perturbation was suggested to have occurred in the late Rhaetian (the late Rhaetian CIE; Mette et al, 2012).…”

“…This trend in δ 13 C has also been identified in some terrestrial successions [Deenen et al, 2010;Whiteside et al, 2010;Dal Corso et al, 2014], reinforcing that it is likely global in nature and that it reflects changes in δ 13 C values of the global oceanatmosphere system. Additional potential excursions predating that across the TJB have been also discovered [Cleveland et al, 2008;Ruhl & Kürschner, 2011;Schaller et al, 2011;Mette et al, 2012;Korte et al, 2017]. The clear major ("main") negative TJB excursion, however, has not be identified in all marine sections [e.g., see Galli et al, 2007;Pálfy et al, 2007;van de Schootbrugge et al, 2008;Götz et al, 2009].…”

“…) [e.g., Popp et al, 1986;Veizer et al, 1986] and because the alteration degree can be assessed by a multitude of physical and chemical techniques [see Veizer, 1983;Marshall, 1992;Ullmann & Korte, 2015 for reviews]. From different regions in Europe, δ 18 O (and δ 13 C) data exist from well-preserved brachiopods of the Late Triassic [Korte et al, 2005[Korte et al, , 2017Mette et al, 2012] and pristine oysters of the earliest Jurassic [Jones, 1992;Korte et al, 2009]. Unfortunately, no continuous dataset over the TJB is available from a single locality.…”

Chemostratigraphy Across Major Chronological Boundaries

The Triassic-Jurassic transition (~201.5 Ma) is marked by one of the largest mass extinctions in Earth's history. This was accompanied by significant perturbations in ocean and atmosphere geochemistry, including the global carbon cycle, as expressed by major fluctuations in carbon isotope ratios. Central Atlantic Magmatic Province (CAMP) volcanism triggered environmental changes and played a key role in this biotic crisis. Biostratigraphic and chronostratigraphic studies link the end-Triassic mass extinction with the early phases of CAMP volcanism, and notable mercury enrichments in geographically distributed marine and continental strata are shown to be coeval with the onset of the extrusive emplacement of CAMP. Sulfuric acid induced atmospheric aerosol clouds from subaerial CAMP volcanism can explain a brief, relatively cool seawater temperature pulse in the mid-paleolatitude Pan-European seaway across the T-J transition. The occurrence of CAMP-induced carbon degassing may explain the overall long-term shift toward much warmer conditions. The effect of CAMP volcanism on seawater 87 Sr/ 86 Sr values might have been indirect by driving enhanced continental weathering intensity. Changes in ocean-atmosphere geochemistry and associated (causative) effects on paleoclimatic, paleoenvironmental, and paleoceanographic con ditions on local, regional, and global scales are however not yet fully constrained.
