Figure 4
Raman spectra of (a) unirradiated and (b) ion-irradiated zircon after applying a pressure up to 37 GPa followed by pressure release (Lang, Zhang et al., 2008). (a) Only traces of zircon were observed in the sample without irradiation, revealing an almost complete transformation to reidite. (b) Only traces of reidite were observed in the irradiated sample indicating a significant increase in zircon stability. The expected reidite Raman modes are labeled by asterisks (*). |
