a He K-edge EELS spectra from the substrate ilmenite and nano-vesicles of the vesicular rim on the CE5Z1002 #2 ilmenite grain. b, c He K-edge EELS spectra from the substrate ilmenite and large vesicles in the highly weathered ilmenite rims (i.e., the npFe0-rich rim and the deeply damaged rim) on the CE5C0200 #2 and CE5Z0204 #1 ilmenite grains, respectively.
