TEM and EDS data of other space weathering features in these grains. (a) BF STEM image of the amorphous island deposited on the grain rim. The white dashed line indicates the original grain surface. (b-e) BF STEM and EDS spectral images of the island feature showing enrichments in Fe and S relative to the underlying grain, as located by the red box in (a). (f) BF STEM image of poorly developed vesicles, as indicated by arrows in the partially amorphous matrix of the orthopyroxene rim. (g) BF STEM image of a well-developed vesicle, indicated by red arrow in the partially amorphous orthopyroxene rim.
