We used surface-enhanced Raman spectroscopy to investigate the chemical composition of the black stains threatening the rock-art paintings of Lascaux Cave, Montignac, France. The stains are mainly composed of melanin from the fungus Ochroconis sp. and the faecal pellets of the collembolan Folsomia candida. Surface-enhanced Raman spectroscopy is a useful technique for revealing the structure of unknown macromolecules in cultural heritage research. Copyright © 2011 John Wiley & Sons, Ltd. The chemical composition of the black stains threatening the rock-art paintings of Lascaux Cave, Montignac, France was studied using surface-enhanced Raman spectroscopy (SERS). The stains are mainly composed of the melanin from the fungus Ochroconis sp. and the faecal pellets of the collembolan Folsomia candida. SERS is a useful technique for revealing the structure of unknown macromolecules in cultural heritage research.
