| 英文摘要 | Synthetic oxides are commonly used as the monitor standards for the trace element analysis of rutile by Electron Probe Microanalyzer (EPMA). Systematic analyses of rutile standards are still lacking. In this study we present a detailed EPMA analysis (CAMECA SXFive) on nine elements (Al, Si, Ti, Fe, Cr, Zr, V, Nb and Ta) in the rutile standard R10. Ti and Si are used as monitor elements. To improve the analytical precision and reduce the detection limit, we have critically adjusted the acceleration voltage, beam current and counting time, and have deducted the interference peak signals. Our results show that the concentrations of Zr (780 +/- 29 x10(-6)) (1SD, n=25), Nb (2799 +/- 66 x10(-6)), V (1276 +/- 33 x10(-6)), Fe (4309 +/- 34 x10(-6)) and Cr (718 +/- 31 x 10(-6)) are well consistent with those analyzed by Secondary Ion Mass Spectrum (SIMS) or Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) within the error range. EPMA analysis in this study exhibits good stability. From a one-month monitoring period, the variations of Nb, Zr, and Cr are within 10%, whereas the variations of V and Fe are within 5%. Our modified techniques improved the analytical precisions of V, Nb and Fe in rutile. The analytical precision of Zr in this study would not significantly affect the results yielded by the Zr-in-rutile thermometer. Therefore, EPMA trace element analysis is an effective approach to understand the formation mechanisms of rutile. The techniques that can potentially improve the analytical precisions of Ta and Fe3+ analyses in rutile are also discussed. |
