An updated REE measurement of Gabbro GOG‐1 was carried out by means of secondary ion mass spectrometry (SIMS). The availability of high amount of rock powder allowed the sample to be well ground and homogenized before analysis. Fused glass pellets were employed for SIMS investigations. REE data were compared with new ICP‐AES and NAA analyses. REE results from all employed analytical techniques show good agreement and are consistent with in‐situ SIMS measurements of REE in major mineral phases forming GOG‐1. Extensive homogeneity tests seem to confirm the possibility to using this rock as a reference material for earth sciences.
