Figure 7
Microbeam EXAFS, P K-edge, of a Fe,Ni phosphide grain in a heterogeneous meteorite section. The beam size is 10 µm × 5 µm. (a) Normalized energy spectrum; (b) k2-weighted EXAFS; and (c) Fourier transform, showing pronounced first shell (9 Fe/Ni) and complex higher shells to ∼4 A. It is noteworthy that this sample contains some S, but the detector resolution is sufficient to separate P from S.
