用多收集器电感耦合等离子体质谱(MICMS)测定了日本地质调查局9个化探标准岩以及BIR-1和BCR-2的176Hf/177Hf比值。我们对BIR-1、BCR-2和JB-1的数据与以前报道的数据一致，证明了本研究所采用的化学程序和同位素测量的合理性。参考岩石具有广泛的176 Hf/177 Hf范围，覆盖由各种火山岩定义的区域，如大洋中脊玄武岩、洋岛玄武岩和与俯冲有关的火山岩。因此，它们适合作为地质样品的Hf同位素测量的岩石标准。
176Hf/177Hf ratios of nine geochemical reference rocks from the Geological Survey of Japan, together with BIR-1 and BCR-2, were determined using multi-collector inductively coupled plasma mass spectrometry. Our data for BIR-1, BCR-2 and JB-1 are in agreement with those previously reported, demonstrating the appropriateness of the chemical procedure and isotopic measurement employed in this study. The reference rocks have a wide range of 176Hf/177Hf covering the field defined by various volcanic rocks, such as mid-ocean ridge basalts, ocean island basalts, and subduction related volcanic rocks. They are therefore suitable as rock standards for Hf isotope measurement of geological samples.
