Raman spectroscopy is applied for the first time on rock art paintingsfrom hunter-gatherers in three different provinces in Patagonia, Argentina (Neuquén, RíoNegro, Chubut). Selected archaeological sites were examined, revealing the local?palette? of the native population and, if possible, the technology used. Moreover,alteration products were investigated to obtain valuable information for a betterconservation and preservation of these magnificent rock art paintings. During a singleresearch campaign sixteen shelters and one cave were investigated which makes thisstudy as one of the most condensed expeditions on measuring rock art paintings. Wewant to evaluate the use of our portable Raman instrument to analyse rock art paintingsunder extreme conditions in Patagonia, Argentina. Several improvements are proposed,to maximize the quality of the research output in such condensed expeditions.
