Similarly to the cross-sections of a traditional excavation, the microstratigraphic transversal cuts of small samples obtained from the walls with rock art show a sequence of numerous layers originated by environmentalfactors and human activities, specially the confection of rock paintings. In this paper we present the results of the study of some micro-stratigraphies fromthe caves of the archaeological site of Oyola (Mountain of El Alto-Ancasti,Catamarca) with the aim of approach the history of production andtransformation of their painted panels. These samples, of approximately 1 mm2, were analysed with Raman microSpectroscopy to characterize each layers. Then, through a morphological comparison of the layers, the cross-sections of many samples were linked in order to elaborate an attempt of stratigraphic sequence that expresses the process of formation of the different panels of these caves.In this presentation we discuss the results obtained, their limits and meaning,at the same time that propose some alternatives to associate the stratigraphicsequences of the walls with the stratigraphic matrix elaborated by theexcavation of the floor of some of these caves. In this way we hope to develop amethodological alternative that allow a better understanding of the multiplesocial practices that shaped and transformed these spaces with prehispanicrock art.
