    Mineralogical controls of the oceanic nickel cycle by Lena Chen, Autum R. Downey, Corey Archer, Susan H. Little, William B. Homoky, Caroline L. Peacock

    Published 2025-08-01
    “…Using nickel (Ni) as an example, we show how manganese (Mn) minerals control its isotopic composition in oxic marine sediments. By analysing synthetic and natural samples, and simulating sediment diagenesis, we find that most Ni isotope variability in modern Mn-rich sediments is driven by the relative contribution of two bonding mechanisms – adsorption to and structural incorporation into Mn oxides – which evolve during Mn mineral aging and transformation. …”
