Experimental determination of Si, Mg, and Ca isotope fractionation during enstatite melt evaporation

These data are elemental and isotopic compositions of samples from a series of levitation evaporation experiments on enstatite melt conducted at 2423-2623 K in pure Ar gas. The Mg, Si, and Ca contents are measured by EPMA, Nb and Ta contents by LA-ICPMS, Mg and Si isotopes by MC-ICPMS, and Ca isotopes by TIMS. The isotopic fractionation factors and evaporative saturation degree of previous evaporation experiments  are also included.
