Fig. 4: Microstructure of majorite-pyrope.

a BSE image of majorite-pyrope (Maj-pyr) in the shock melt vein. The blue lines represent the locations where Foil 3 and Foil 4 were extracted. b Raman spectrum of majorite-pyrope (R571). c HAADF image showing the microstructure of Foil 3. d HAADF image of majorite-pyrope showing some bright nanoparticles within it. e The nanoparticles are composed of subgrains, including metallic iron and sulfide. f HRTEM image of majorite-pyrope and its SAED pattern along the [110] zone axis. g HRTEM image of metallic iron and sulfide. The inset is the FFT pattern of metallic iron. h HAADF image showing the microstructure of Foil 4. The inset shows the SAED pattern of majorite-pyrope along the [111] zone axis. i EDS map showing the metallic iron nanoparticles and (Fe, Ti)-oxides in the shock melt vein. j TEM image of metallic iron and majorite-pyrope. The inset shows the CBED pattern of metallic iron along the [\(1\bar{1}3\)] zone axis.
