“…1022-1026 cm -1 . This band position seems to correspond to that of anhydrite III as identified by Hernanz in the red paintings of Yabrai Mountain (China) [61]. In our observations, this band was always identified in zones where gypsum was observed.…”

“…Fluorescence caused by the encrustrations in the shelter Alero Maqui completely blocked or overwhelmed the Raman signal in such a way that the identification of main chromophores was impossible. Only, calcite was identified on the red motifs of Guillelmo Lake while on the rock surface albite (NaAlSi 3 O 8 ) [46,61] (Fig. 3 c) is present.…”

“…4 spectra collected from rock supports near paintings 58 and 51 (a-b) and 28a (red guanaco painting(c), from the shelter Paredón Lanfré, are presented. Albite [46,61] and α-quartz [42][43] can be found on the rock surfaces but also inside coloured figures while haematite [39,45] is the main chromophore of all the red paintings. In the case of the red guanaco painting the band at 658 cm -1 corresponds to iron oxide with low degree of crystallinity [45].…”

An extensive in situ Raman spectroscopic campaign was performed on archaeological sites in three different provinces in Patagonia, Argentina (Neuquén, Río Negro and Chubut). 16 open air shelters located in different environments (forests, ecotones, steppes) were investigated and interpreted in terms of pigments used and the identification of substrata. Special attention was given to the alteration products and accretions that were found on the rock art paintings of the shelters and on the surface of the rock walls, as they can affect and damage this magnificent works of art. Haematite (α-Fe 2 O 3) was the main chromophore that was found on the red paintings of the most of the shelters studied. The green earth glauconite, was identified only in one case, by using a red (785 nm) and a green laser (532 nm). Other minerals and silicates were found on the couloured areas but also on the rock support. Calcite (CaCO 3) and gypsum (CaSO 4 •2H 2 O) crystallization was identified on the paintings, crusts and rock surfaces, in combination or alone, and are associated with weathering. In some cases the shelters were so severely degraded that no Raman signal of pigments and/or other components could be retrieved. Calcium oxalates were also detected in several figures and motifs in different shelters.
