Zinc isotopic variations of oceanic crust: Insights from oceanic gabbro cumulates and MORBs

This dataset includes (1) Chemical and isotopic compositions of the SWIR gabbros, EPR MORBs, SMAR MORBs and standards (Table 1); (2) Mineral mode of the SWIR gabbros (Table S1); (3) Modeling calculation of Zn isotopic fractionation during magmatic differentiation of mid-ocean ridge magmas (Table S2).
