    • Gradual warming prior to the end‐Permian mass extinction 

      Gliwa, JanaORCIDiD; Wiedenbeck, Michael; Schobben, Martin; Ullmann, Clemenz V.; Kiessling, WolfgangORCIDiD; Ghaderi, AbbasORCIDiD; Struck, UlrichORCIDiD; Korn, DieterORCIDiD (Palaeontology, 2022-09-06)
      The biggest known mass extinction in the history of animal life occurred at the Permian–Triassic boundary and has often been linked to global warming. Previous studies have suggested that a geologically rapid (<40 kyr) ...

    • Inter‐laboratory Characterisation of Apatite Reference Materials for Chlorine Isotope Analysis 

      Wudarska, AlicjaORCIDiD; Słaby, Ewa; Wiedenbeck, Michael; Barnes, Jaime D.; Bonifacie, Magali; Sturchio, Neil C.; Bardoux, Gérard; Couffignal, Frédéric; Glodny, JohannesORCIDiD; Heraty, Linnea; John, TimmORCIDiD; Kusebauch, Christof; Mayanna, Sathish; Wilke, Franziska D. H.; Deput, Ewa (Geostandards and Geoanalytical Research, 2020-12-25)
      Here we report on a set of six apatite reference materials (chlorapatites MGMH#133648, TUBAF#38 and fluorapatites MGMH#128441A, TUBAF#37, 40, 50) which we have characterised for their chlorine isotope ratios; these RMs ...

    • Tourmaline Reference Materials for the In Situ Analysis of Oxygen and Lithium Isotope Ratio Compositions 

      Wiedenbeck, Michael; Trumbull, Robert B.; Rosner, Martin; Boyce, Adrian; Fournelle, John H.; Franchi, Ian A.; Halama, Ralf; Harris, Chris; Lacey, Jack H.; Marschall, HorstORCIDiD; Meixner, Anette; Pack, AndreasORCIDiD; Pogge von Strandmann, Philip A.E.; Spicuzza, Michael J.; Valley, John W.; Wilke, Franziska D.H. (Geostandards and Geoanalytical Research, 2020-11-07)
      Three tourmaline reference materials sourced from the Harvard Mineralogical and Geological Museum (schorl 112566, dravite 108796 and elbaite 98144), which are already widely used for the calibration of in situ boron isotope ...

    • Water contents of nominally anhydrous orthopyroxenes from oceanic peridotites determined by SIMS and FTIR 

      Wenzel, Kirsten T.ORCIDiD; Wiedenbeck, Michael; Gose, Jürgen; Rocholl, Alexander; Schmädicke, EstherORCIDiD (Mineralogy and Petrology, 2021-08-27)
      This study presents new secondary ion mass spectrometry (SIMS) reference materials (RMs) for measuring water contents in nominally anhydrous orthopyroxenes from upper mantle peridotites. The enstatitic reference orthopyroxenes ...
