| −1.04 / −0.1 ‰ | magmatic sulfides (pentlandite, pyrrhotite, chalcopyrite) Magmatic sulfides are generally lighter than the host basalts, owing to separation between sulfide and silicate liquids with equilibrium fractionation. Values for all the main nickel sulfides of the province, not for a single deposit. | Hofmann et al. 2014, Ni isotopes in magmatic sulfide ore deposits | ||
| 0.07 / 1 ‰ | host basalts (Siberian Traps) Negative correlation with nickel content: the isotopic fractionation results from sulfide saturation of the silicate magma. | Ni isotopes trace sulfide-silicate liquid immiscibility, Siberian Trap basalts at Noril's… (2023) |
