BSE images of icosahedrite in the Khatyrka CV3 carbonaceous chondrite. a Grain 126A of Khatyrka CV3 carbonaceous chondrite. A red dashed box indicates the region to be enlarged in b. b The area where there is the metal assemblage containing the icosahedral phase (icosahedrite). c The enlarged image of the region indicated by a red dashed box in the panel b. d Electron backscatter diffraction pattern of the icosahedral phase obtained from the region marked with a cross in the inset. The pattern matches that predicted for a face-centered icosahedral quasicrystal
