Figure 6
XRF image of P (red), S (green) and Ca (blue) in a meteorite thin section shows a small grain (single 4 µm pixel) with high P and Ca. XANES spectra of this location were measured at P, S and Ca edges with a 2 µm × 3 µm beam. The sample was provided by the Field Museum of Natural History, Chicago, IL, USA, courtesy of P. Heck, S. Simon, S. Wirick and S. Sutton.
