Figure 5From: A transmission electron microscope study of Itokawa regolith grainsBright-field STEM image of the rim in particle RA-QD02-0211 and corresponding element ratio profiles. A bright-field STEM image of the disordered rim in particle RA-QD02-0211 (left) and corresponding element ratio profiles from the core through the rim of the grain, indicated by the yellow arrow in the STEM image (right). The element profiles show a thin outermost later that is Si-enriched.Back to article page
