Data are reported for rare earth elements (REE) in three geological glass reference materials (BIR‐1G, BHVO‐2G and BCR‐2G) using a UV (266 nm) laser ablation ICP‐MS system and the classical (HF‐HClO 4 ) acid decomposition method, followed by conventional nebulisation ICP‐MS. External calibration of laser ablation analyses was performed using NIST SRM reference materials with internal standardisation using 29 Si and 44 Ca. Replicate analyses of reference basaltic glasses yielded an analytical precision of 1‐5% (RSD) for all the elements by solution ICP‐MS and 1‐8% (RSD) by laser ablation ICP‐MS. The relative differences between the REE concentrations measured by solution and laser ablation ICP‐MS compared with the reference values were generally less than 11 % for most elements. The largest deviations occurred for La determined by solution ICP‐MS in BIR‐1G. The results of both solution and laser ablation ICP‐MS agreed well, generally better than 7%, with the exception of La, Pr and Sm in BIR‐1G. The measured REE laser ablation data for BIR‐1G, BHVO‐2G and BCR‐2G agreed with the previously published data on these basaltic reference glasses, within a range of 0‐10% for most elements. No significant influences were observed for the predicted spectral interferences on some REE isotopes in the analysis of basaltic glasses.
