Iron isotope measurements of mineral separates in partially serpentinized peridotite from the New Caledonia Ophiolite

This dataset contains Fe isotope measurements of mineral separates in partially serpentinized peridotite from the New Caledonia Ophiolite. These results demonstrate that magnetite and awaruite are isotopically heavy relative to relict minerals (olivine, pyroxene), while serpentinite is isotopically heavy relative to relict grains. This finding is consistent with the predicted sense of fractionation from chemical modeling.
