| Research Abstract |
The main subject of this research is to develop in-situ analytical technique to determine concentration of fluid-mobile elements and discuss elemental re-distribution at small bodies on the Solar system by fluid related processes. The author succeeded to optimize sample preparation and to have reliable olivine standards by conventional technique, and established in-situ boron-quantitative-analysis with sub-ppm level. The technique was applied to chondrules and abundances of boron in each phase were determined.
