“…The research of diachronic processes of production and transformation of rock art panels is a worldwide problem that raises intriguing challenges to approach the elucidation and identification of different painting events [1][2][3][4][5][6]. In last decades, archaeometric studies have been a powerful tool to understand the materials employed in paintings [4,[7][8][9][10][11] as well as the natural and/or anthropic phenomena that affect them throughout time [12][13][14][15][16][17]. Also, direct absolute chronology of paintings has demonstrated to be a powerful tool in this matter [18,19].…”

Could not be possible that rock paintings with similar hues and morphologies were the results of different painting events inside a cave but distanced in time? Is there any archaeometric approach that allows us to evidence these subtle differences? Aiming to address these inquires, in this work are presented the potentials of new physicochemical lines of evidence for characterization and differentiation of painting mixtures. This will improve the understanding of the technical heterogeneity and temporal complexity of painting sets executed in a particular archaeological site. In order to explore these points, the results obtained in the micro-stratigraphic studies of samples taken from the painted walls of Oyola, an archaeological site situated in the northwest of Argentina, are presented. These samples have been analyzed by micro-Raman spectroscopy (mRS) and scanning electron microscopy with energy dispersive X-ray (SEM-EDS). The differences found by cross-section chemical studies could be explained as a consequence of two situations: 1- differences in the painting’s chemical components, either in the pigments involved or additives used; and, 2- differences in the physical properties of the mixtures such as stratum thickness and/or particle size. Also, in this article is explained each of the hypothesis, presenting the limits of these interpretations and pointing out future research challenges. As we discussed, it could be possible that the chemical and physical differences found between painting mixtures were the material expression of varied types of pictorial techniques.
