Measurement of SIMS Instrumental Mass Fractionation of Pb Isotopes During Zircon Dating

Stern, Richard; Bodorkos, Simon; Kamo, Sandra L; Hickman, Arthur H; Corfu, Fernando


An igneous zircon reference material (OG1) was characterised for U-Pb isotopes by ID-TIMS, and utilised to evaluate SIMS (SHRIMP) instrumental mass fractionation (IMF) of radiogenic Pb isotopes (207 Pb*/206Pb*). The TIMS207Pb*/206Pb* reference value for OG1 was 0.29907 ± 0.00011 (95% confidence limit), 3465.4 ± 0.6 Ma. The high207Pb* (∼ 30 μg g-1), negligible common Pb, and isotopic homogeneity permitted precise (± 1-2‰)207Pb*/206Pb* measurements within the analytical sessions. External...[Show more]
