| Research Abstract |
Oxidation experiments and shock recovery experiments of stony meteorites have been demonstrated in order to investigate the effects of high-temperature, -pressure, and -oxygen fugacity on the mineralogy of the meteorites. TEM analyses of the recovered samples showed that 1) a correlation between mid-infrared spectra and a superstructure transition of Fe-rich olivine during oxidation, and 2) dehydration of hydrous minerals is not significant in shock heating at ~1 GPa. Static compression experiments of plagioclase and TEM and Raman analyses of the recovered samples, revealed that 3) the pressure-induced amorphization of plagioclase has considerable temperature and time dependence.
