| Outline of Final Research Achievements |
In order to understand the condensation conditions of enstatite in cometary materials, an experimental setup, which enables to control the temperatures of vapors and substrates, and the Mg/Si ration of the gases, was developed. Condensation experiments of gases with SiO2/(SiO2+MgO) of 0.05-0.9 were carried out and forsterite, and ortho- and clone-enstatite grains were obtained as condensates. The results indicate that not only supersaturation ratio but also a trace amount of cations are important to form clinoenstatite.
