| Outline of Final Research Achievements |
This project aimed to set up and evaluate a new method for measuring multiple isotopes of Hf, Nd, and Sr using LA-MC-ICP-MS. Apatite as waste during zircon separation was used for Sr and Nd measurements that (reuse of apatite) is the most important point in this study. As the result, we got very good Sr and Nd data from standard apatite indicating the method was set up correctly. We also measured Hf, Nd, and Sr isotopes of zircon and apatite separated from natural granitic samples. The data are in good agreement with the data obtained from wet analyses using TIMS.
