Caption: Figure 2.
SSW-induced surface alteration in terrestrial ilmenite. (a)–(c) SEM images of ilmenite showing SSW-induced surface damage after exposures of 0 hr (a), 4 hr (b), and 7 hr (c). (d)–(g) HAADF cross-sectional images of ilmenite rims irradiated for 2 hr (d), 5 hr (e), 7 hr (f), and 12 hr (g). Corresponding fluence and lunar-equivalent years are shown in Table 1. Bright spots indicate npFe0, while dark regions correspond to vesicles and/or planar defects.
