Magnesium isotopic homogeneity of San Carlos olivine: a potential standard for Mg isotopic analysis by multi‐collector inductively coupled plasma mass spectrometry

Abstract

The new data are consistent with the narrow δ(26) Mg range of mantle olivine worldwide, while they stand in contrast to the wide range measured on the same San Carlos olivine powder in different laboratories. Therefore, previous inter-laboratory discrepancies reflect analytical artifacts instead of sample heterogeneity, and San Carlos olivine is a suitable standard for Mg isotopic analysis.
