Magnesium isotope compositions of Solar system materials (NERC grant NE/L007428/1)
The data are magnesium (Mg) isotope composition, i.e. the relative difference of isotope ratios as defined in Coplen (2011, doi: 10.1002/rcm.5129). The reference was DSM-3 (see Galy et al., 2003, doi: 10.1039/b309273a) and data are given in per mil. Samples consisted of terrestrial peridotites and basalts as well as a suite of meteorites including chondrites, shergottites, diogenites and one angrite. A large portion of the data have been published in Hin et al. (2017, doi: 10.1038/nature23899).

The majority of samples were analysed as bulk rock powders; a small number consisted of either hand-picked or micro-drilled phases, as indicated in the data tables. Samples were prepared for analysis by acid digestion and ion chromatography to isolate Mg from its matrix. The Mg isotope ratios were analysed by multi-collector inductively coupled mass spectrometry following the critical mixture double spiking theory described in Coath et al. (2017, doi: 10.1016/j.chemgeo.2016.12.025). Full details of the methods have been published in Hin et al. (2017, doi: 10.1038/nature23899).
