Short summary
This is a preliminary study using a synchrotron light source to generate elemental maps, incorporating oxidation states, with a spatial resolution of <1 µm for individual grains within the K-feldspar density fraction. The elemental fingerprint characterizing grains with a signal suitable for infrared radiofluorescence dating reveals high levels of K, Pb, and Ba coupled with low levels of Fe and Ca. In contrast, grains exhibiting higher proportions of Fe and Ca produce an odd signal shape.
