We identified minerals on the surface of polished surfaces of Itokawa dust particles by micro- Raman spectroscopy. Their sizes ranged from 30 to 150 μm across. Olivine, pyroxenes, plagioclase and chromite were identified, which correspond to SEM/EDX observations and analyses of these samples. Although Raman spectroscopy is suitable for the identification of maskelynite (diaplectic glass transformed from plagioclase), we could not find maskelynite in all of the samples investigated. This fact suggests that the shock stage of the samples did not reach S4, which is consistent with the other results of the Hayabusa initial analyses.
