Fe K-edge µ-XANES spectra recorded at the cross sections of the artiodactyl [(c) Fe-rich spot, (e) Fe-poor spot] and perissodactyl [(d) Fe-rich spot, (f) Fe-poor spot] bones. A macro-XANES spectrum (b) of the artiodactyl specimen recorded at the centre of the cross section and the goethite reference (a) are also included. The fitting of the pre-edge peaks using four Lorentzian functions is shown in the inset. |
