a Transmission electron microscopy (TEM) bright-field image of the edge of the CE5C0200 #1 ilmenite grain. Black rectangles represent the locations of the high-resolution (HR) TEM images shown in (b) and (c). b, c HRTEM images of the outer and inner regions within the space-weathered rim, and the white lines represent the (110) and (018) lattice fringes of α-Fe and ilmenite, respectively. d High-angle annular dark-field (HAADF) image of the CE5C0200 #1 ilmenite rim and its corresponding quantitative energy-dispersive element maps for Fe, Ti, and O, and the red circles and numbers represent the locations of EELS spectra acquisition in (e) and (f). e, f He K-edge and Ti L2,3 electron energy-loss spectra (EELS) from the substrate ilmenite and ilmenite rim in CE5C0200 #1.
