Abstract The behavior of nickel (Ni) isotopes during magmatic differentiation is not adequately explored. Here, we find that tholeiitic rocks in the Kīlauea Iki (KI) lava lake, Hawai'i, show progressively lighter Ni isotopic compositions with increa

Nickel isotope fractionation patterns in continental ultramafic environments generally show a depletion of delta Ni-60 in weathered rocks and an enrichment in bedrock samples. The present study focuses on stable Ni isotope fractionation patterns in c

International audience; The fractionation of Ni isotopes during Ni coprecipitation with calcite was measured at pH = 6.2 and pCO 2 = 1 atm as a function of calcite growth rate. Light Ni isotopes are preferentially incorporated into calcite during its
