Portable Raman spectroscopy is applied for the first time on rock art paintings from hunter-gatherers in three different provinces in Patagonia, Argentina (Neuquen, Rio Negro and 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 better conservation and preservation of these magnificent rock art paintings. During a single research campaign, 16 shelters and one cave were investigated, which makes this study as one of the most condensed expeditions on measuring rock art paintings. Here, we evaluate the use of our portable Raman instrument to analyse rock art paintings under extreme conditions in Patagonia, Argentina. Several improvements are proposed to maximize the quality of the research output in such condensed expeditions. Copyright (c) 2017 John Wiley & Sons, Ltd.
