Abstract

In order to facilitate identification of tridymite modifications using micro–Raman spectroscopy, the Raman spectra of synthetic and natural tridymite modifications (MC, MX–1, and PO–10) including low frequency region (ν = 15–200 cm−1) are measured. The Raman spectrum of MX–1 is reported for the first time. All modifications revealed the characteristic peaks below 150 cm−1. Using the compiled Raman spectra, tridymite modifications of the reported Raman spectra from meteorites in the literature were identified. It revealed that not only MC, but PO–10 modification exists in the meteorites.
