The first use of portable Raman instrumentation for the in situ study of prehistoric rock paintings in Patagonian sites

Summary: | Portable Raman spectroscopy is applied for the first time on rock art paintings from hunter‐gatherers in three different provinces in Patagonia, Argentina (Neuquén, Río 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 © 2017 John Wiley & Sons, Ltd.
Portable Raman spectroscopy is applied for the first time on rock art paintings from hunter‐gatherers in three different provinces in Patagonia, Argentina (Neuquén, Río Negro, and Chubut). During a single research campaign, 17 sites were investigated, which makes this study as one of the most condensed expeditions on measuring rock art paintings. The purpose of this paper is to describe possible difficulties that are encountered during in situ Raman measurement of Patagonian prehistoric rock art, and some possible improvements are suggested. |
