(A) Visible light picture of sample 4 (P. Carlsberg 649) (B) macro and micro XRF maps of Cu (fitted and normalized by the intensity of incident beam). The areas were XANES spectra were collected are highlighted. The red-blue maps are the superimposition of Cu and Fe maps, from the detailed map (C) Average XANES spectra from area 1, and its decomposition by LCF.
