| Research Abstract |
Based on experimental study, we have proposed a model of solid particle evolution from the universe to the solar system, where silicate minerals observed were crystallized from amorphous silicates. Stardust and Hayabusa sample analysis shows that cometary material is amorphous silicate mixed with high-temperature materials and S-type asteroid material is ordinary chondrite suffered by thermal metamorphism. Amorphous silicates with high reactivity and compositional valiety caused prompt reaction during hydrothermal metamorphism. These results showed that source material of the solar system is consistent with amorphous silicates.
