Two quartz samples of igneous origin, UNIL ‐Q1 (Torres del Paine Intrusion, Chile) and BGI ‐Q1 (Shandong province, China), were calibrated for their oxygen isotope composition for SIMS measurements. UNIL ‐Q1 and BGI ‐Q1 were evaluated for homogeneity using SIMS . Their reference δ 18 O values were determined by CO 2 laser fluorination. The average δ 18 O value found for UNIL ‐Q1 is 9.8 ± 0.06‰ and that for BGI ‐Q1 is 7.7 ± 0.11‰ (1 s ). The intermediate measurement precision of SIMS oxygen isotope measurements was 0.32–0.41‰ (2 s ; UNIL ‐Q1) and 0.40–0.48‰ (2 s ; BGI ‐Q1), respectively. While less homogeneous in its oxygen isotope composition, BGI ‐Q1 is also suitable for SIMS trace element measurements.
