Akimotoite (Ak), ringwoodite (Rwt) and vitrified perovskite in an impact-melt pocket. Ringwoodite was identified in both the centre (no. 4) and rim of the impact-melt pocket. Raman spectra of the low-P equivalents (low-Ca pyroxene and olivine) are shown for comparison (no. 2 and no. 3). Bright minerals within the impact-melt pocket were identified using coupled EMP and Raman spectroscopy as pyrrhotite. Numbers next to the circles indicate the Raman spot analyses.
