英文摘要To meet the rapid development of zircon U-Pb geochronology and Hf-O isotope geochemistry, it is imperative to develop well-characterized zircon reference materials for microbeam analysis. Here, zircon KV01 separated from the Kaap Valley pluton, South Africa is introduced as a potential Archean reference material for microbeam U-Pb age and Hf-O isotope determination. SIMS and LA-ICP-MS U-Pb isotopic measurements gave grand mean(207)Pb/Pb-206 ages of 3233 +/- 16 Ma (2s,n=90) and 3230 +/- 26 Ma (2s,n=52), which are consistent with reported CA-ID-TIMS results. Slight heterogeneity of oxygen isotopes is revealed by SIMS analyses that yielded a relatively large delta O-18 range of 4.61-6.51 parts per thousand. Among them, the zircon grains with clear oscillatory zones give a grand mean delta O-18 value of 6.17 +/- 0.33 parts per thousand (2s), which is suggested to record the primary O isotopic compositions. The homogeneity in the Hf isotopic compositions of KV01 zircon was checked by the laser ablation and solution MC-ICP-MS methods. They yielded consistent results with a recommended(176)Hf/Hf-177 ratio of 0.280810 +/- 0.000013 (2s). The results reported here demonstrate that KV01 zircon could be a reliable reference material for microbeam(207)Pb/Pb-206 age and Hf isotope determinations of ancient zircons, and be suitable as a quality monitor for SIMS oxygen isotopic analysis.
