TEM and EDS data of nanophase Fe in the rim of orthopyroxene. (a) HAADF image of the orthopyroxene grain rim showing a high concentration of Fe nanoparticles. (b-e) EDS maps of the region indicated by the yellow box in (a). An individual particle is indicated by a white circle in (b-e). (f) Intensity profiles for Si, O, Fe, and Mg taken across the identified particle, indicated by a dashed yellow line. Note the obvious Fe peak, the relatively consistent Mg and O concentrations, and the Si enrichment bordering the particle.
