摘要
秘鲁南部塔克纳地区有前哥伦布时期人类居住的考古遗迹,其中包括米库拉岩画。对这些岩画进行年代测定的现有方法存在很大的不确定性,而且存在缺乏客观验证的说法。这项研究采用了先进的高光谱分析技术,特别是利用 SPECIM IQ 摄像机,对这些岩画的现有年代建议进行重新评估。所采用的分析技术是非破坏性的,可以捕捉到广泛波长范围内的光谱数据。通过与邻近的完整区域进行比较,可以对太阳照射造成的斑驳程度进行定量评估。使用 SPECIM IQ Studio 软件和 Matlab 分析了来自不同岩画的数据。分析区分了选定巨石上的 "雕刻 "区域和 "涂漆 "区域。通过比较这些区域的反射比,可以了解不同雕刻的潜在相对年代。研究结果对根据岩画的文化分类方案确定的已有年代提出了质疑。这项研究强调了高光谱分析在完善岩画年代测定方面的作用,同时也表明,如果不进一步提高分辨率,这种方法无法取代多种方法。
Contribution of hyperspectral analysis in relative dating applied to Miculla petroglyphs (Peru)
The Tacna region in southern Peru hosts archaeological remnants of Pre-Columbian period human occupations, including the Miculla Petroglyphs. Existing methods for dating these petroglyphs present substantial uncertainties and are subject to claims lacking objective validation. This study employs advanced hyperspectral analysis, specifically utilizing the SPECIM IQ camera, to reevaluate existing chronological proposals for these petroglyphs. The employed analytical technique is non-destructive and captures spectral data across an extensive range of wavelengths. This allows for a quantitative assessment of patination levels attributable to solar exposure, in comparison to adjacent intact areas. Data from various petroglyphs were analyzed using SPECIM IQ Studio software and Matlab. The analysis differentiated between “engraved” and “varnished” regions on selected boulders. Reflectance ratios between these areas were compared to provide insights into the potential relative ages of different sets of engravings. The results question pre-existing chronologies based on cultural classification schemes for the petroglyphs. While the study underscores the utility of hyperspectral analysis in refining petroglyph dating, it also indicates that this method cannot replace a multi-method approach without further resolution refinement.
