Raman spectroscopy stands as a first choice technique for the analysis of rock art paintings. The ability to measure non-destructively painting layers, degradation crusts and substrata are some of the advantageous features of the technique. Moreover, it can be used as an indicator of the existence of organic components that can be found in rock art paintings (e.g. blood, animal fat etc.). Although, micro-Raman spectroscopy has been proven to be suitable for analysing powders and cross sections, mobile Raman instrumentation has also been used for the direct analysis of rock art paintings.Raman spectroscopy stands as a first choice technique for the analysis of rock art paintings.
