| Research Abstract |
Micro-sublimation method was applied for separation of boron from silicate rocks. Suitable experimental condition was established. Micro-mill technique was utilized for sampling of small area like phenocryst in volcanic rock. Significant increase in boron blank level during milling was found. Analytical result for rock standards was disagree with recommended values, requiring further analytical improvement. It is too early to apply to natural samples.
