This data set contains bulk rock, mass-dependent magnesium isotope compositions of chondrites (carbonaceous, ordinary and enstatite) as well as (ultra-)mafic terrestrial rocks, Martian meteorites, diogenite meteorites, and an angrite. They were analysed to investigate Solar System heterogeneity and planet formation processes. All data were produced by wet chemical analysis on a multi-collector inductively coupled plasma mass spectrometer following separation of magnesium from its matrix through ion exchange chromatography in a clean laboratory. A 26Mg-25Mg double spike was added prior to analysis to overcome matrix effects during mass spectrometric analysis, ensuring the highest accuracy (<0.005‰/amu) and precision (2 s.e.m. 0.010‰ or better). Terrestrial samples include two ocean island basalt geological reference materials (BHVO-2 and BIR-1), three mid-ocean ridge basalts, a variety of lherzolites and harzburgites, and Japanese dunite reference material JP-1.
