Average major (wt%) and trace element (ppm) compositions, as well as iron and zinc isotopic compositions (‰) of mineral separates from harzburgites, dunites and chromitites in the Kudi ophiolite

The dataset presents high-precision Fe and Zn isotopic compositions, combined with major and trace elements, for mineral separates (olivine, orthopyroxene, and chromite) from high-Al chromitites and associated peridotites of the Kudi ophiolite in the northwestern Tibetan Plateau, to elucidate the mechanism controlling isotope fractionation during chromitite formation.
