Scanned macroscopic image of resin embedded sediment from Lago Plomo (a). Microscopic image and elemental maps derived from XRF scanning of resin embedded sediment slabs (b). Elemental maps show Fe/Si and Fe/Ca ratios, respectively. Light layers in the photography have higher relative Fe contents and darker layers are enriched in Si and Ca. > max. resolution
