Abstract

Lithic raw material variation is valuable for assessing the scale of human mobility, differential access to and from raw material sources, and prehistoric exchange patterns. Recent advancements in non-destructive reflectance spectroscopy have proven to be more accurate in provenance investigations compared with the macroscopic (visual) identification technique for lithic artifacts. Here, we use visible/near-infrared reflectance and Fourier transform reflectance spectroscopy on a collection of 845 lithic bifaces at Poverty Point (16WC5) site in northeastern Louisiana, a UNESCO World Heritage site that is well-known for the presence of nonlocal materials, including stone tools. This study describes the first systematic approach to analyzing and interpreting hyperspectral reflectance data for cryptocrystalline silicate (e.g., chert and flint) artifacts at Poverty Point site. The chert materials identified in this study reaffirm the idea that tool stones arriving at the Poverty Point site came from diverse geologic sources, covering an expansive geographic area.

使用无损反射光谱法评估贫困点（16WC5）的原材料多样性

石器原料的变化对于评估人类流动性的规模、获取原料来源的差异以及史前交换模式具有重要价值。与宏观(视觉)鉴定技术相比，非破坏性反射光谱技术的最新进展已被证明在石器文物的来源调查中更为准确。在这里，我们使用可见光/近红外反射光谱和傅立叶变换反射光谱对路易斯安那州东北部贫困点(16WC5)遗址的845块石质双面面进行了分析，该遗址是联合国教科文组织世界遗产，以其非本地材料的存在而闻名，包括石器。本研究首次系统地分析和解释了贫点遗址隐晶硅酸盐(如燧石和燧石)人工制品的高光谱反射率数据。在这项研究中发现的燧石材料再次证实了到达贫穷点遗址的工具石来自不同的地质来源，覆盖了广阔的地理区域。

期刊介绍： Geoarchaeology is an interdisciplinary journal published six times per year (in January, March, May, July, September and November). It presents the results of original research at the methodological and theoretical interface between archaeology and the geosciences and includes within its scope: interdisciplinary work focusing on understanding archaeological sites, their environmental context, and particularly site formation processes and how the analysis of sedimentary records can enhance our understanding of human activity in Quaternary environments. Manuscripts should examine the interrelationship between archaeology and the various disciplines within Quaternary science and the Earth Sciences more generally, including, for example: geology, geography, geomorphology, pedology, climatology, oceanography, geochemistry, geochronology, and geophysics. We also welcome papers that deal with the biological record of past human activity through the analysis of faunal and botanical remains and palaeoecological reconstructions that shed light on past human-environment interactions. The journal also welcomes manuscripts concerning the examination and geological context of human fossil remains as well as papers that employ analytical techniques to advance understanding of the composition and origin or material culture such as, for example, ceramics, metals, lithics, building stones, plasters, and cements. Such composition and provenance studies should be strongly grounded in their geological context through, for example, the systematic analysis of potential source materials.
