| Outline of Final Research Achievements |
We developed a new system which enable us to observe the re-crystallization process from melted droplet of silicate material, in order to investigate the formation process of chondrules. We can image the time evolution of the crystallization process by transmitted light image of the X-ray through the melted sample, by the system. In addition, We included X-ray micro computed tobmogprahy technique in our system. Using this system, we succeeded to observe the formation process of crystals inside the melted droplets during crystallization three dimensionally. We investigated formation process of chondrules with pyroxene composition by our 4D (3D+time evolution), and several characteristics during melting and crystallization.
