Fig. 3: Summary of the Ni isotopic compositions reported in this study and previously published data.
From: Nickel isotopes link Siberian Traps aerosol particles to the end-Permian mass extinction

Rivers and the global ocean are from ref. 36, and Fe–Mn crusts are from refs. 35,45. Carbonates and OMZ sediments are from ref. 43. Magmatic sulphides are from refs. 38,48. Organic-rich black shale and mudstone are from ref. 47 and sulphidic Black Sea sediments are from ref. 33. The comparable light Ni isotopic compositions between the magmatic sulphides and our data are highlighted in orange.
