Abstract

Abstract : New zircon reference materials for in situ zircon radiogenic Hf isotope and stable Zr isotopic determinations made by laser ablation multi‐collector inductively coupled plasma‐mass spectrometry (LA‐MC‐ICP‐MS) are required due to high data productivity and consequently high reference material consumption rate. This study examines a new natural zircon for Zr isotope ratios by double spike thermal ionisation mass spectrometry (TIMS), and for Hf isotopes by bulk solution nebuliser (SN)‐MC‐ICP‐MS with both Zr and Hf determined by LA‐MC‐ICP‐MS. A total of five zirconium isotope measurements from drilled zircons, determined by TIMS, yield a mean δ 94/90 ZrIPGP‐Zr value of ‐0.09 ± 0.06‰ (2 s ). Five and eight hafnium isotope measurements for powders from the drilled zircons and Ban‐1‐4 by SN‐MC‐ICP‐MS, yield mean 176 Hf/ 177 Hf ratios of 0.282985 ± 0.000011 (2 s ) and 0.282982 ± 0.000007 (2 s ), respectively. The mean δ 94/90 ZrIPGP‐Zr value and 176 Hf/ 177 Hf ratio determined by LA‐MC‐ICP‐MS analyses are ‐0.06 ± 0.09‰ (2 s, n = 504) and 0.282985 ± 0.000035 (2 s, n = 327), respectively. The isotopic homogeneities suggest that the Ban‐1 zircon is a suitable reference material for microbeam Zr and Hf isotopic measurements. Key Points: Ban‐1 is a new natural zircon reference material for LA‐MC‐ICP‐MS Zr and Hf isotopic determinations. The recommended δ 94/90 ZrIPGP‐Zr value for Ban‐1 is ‐0.09 ± 0.06‰ (2 s ). The recommended 176 Hf/ 177 Hf ratio for Ban‐1 is 0.282983 ± 0.000009 (2 s ).
