是否有可能检测出由自然或人为结核覆盖的岩画？在这项工作中，提出了一种方法来发现和表征潜在的绘画。这种方法结合了从绘画和支撑岩石中提取的微地层样品的显微拉曼和SEM-EDS的化学研究。作为一个研究案例，介绍了在阿根廷西北部奥约拉考古遗址进行的研究。此外，本文还对所提出的方法进行了全面的评价，指出了它们作为理解岩画生产和转化的历史过程的工具的可能性和局限性。为此，该方法被证明是一种成功的绘画检测探索方法，在与非侵入性表征技术相补充时，扩展了其功能。
Is it possible to detect rock paintings coated by natural or anthropic concretions? In this work, a methodology to discover and characterize underlying paintings is proposed. This approach combines chemical studies by micro-Raman and SEM-EDS of micro-stratigraphic samples taken from the paintings and support rock. As a case of study, it is described the research performed in the archeological site of Oyola in the northwest of Argentina. Strong evidences of red, black, and white hidden paintings have been found. In addition, the method herein presented is thoroughly evaluated pointing out their possibilities and limitations as a tool for the understanding of the historical processes involving production and transformation of the rock art panels. To this end, the methodology was proofed to be a successful exploratory approach for painting detection, expanding its capabilities when complemented with non-invasive characterization techniques.
