Abstract

This paper reviews the different archaeological sites of Pampa where there are obsidian records and presents the results of the geochemical and technological analysis of two obsidian projectile points recovered from the Middle Negro River, Uruguay. Using X-ray fluorescence (XRF), two distinct sources were identified: Cerro de las Planicies/Lago Lolog (CP/LL1) and Telsen/Sierra Negra (T/SN1), both located in north and central Patagonia, approximately 1600 km from the study area. The results suggest that obsidian points transported to Uruguay exceed previous records of distances recorded for South America and are in the range of the greatest distances in the world. The technological and morphological features of the points suggest different trajectories of transport, chronology, use and curation. This contributes to broader discussions on long-distance interactions, technological organization, the social and symbolic significance of exotic raw materials in the prehistoric societies of southeastern South America.

南美外来原料的流动、流通和长途运输：乌拉圭巴塔哥尼亚黑曜石点的记录

本文综述了潘帕平原不同考古遗址的黑曜石记录，并介绍了在乌拉圭内内罗河中部发现的两个黑曜石抛射点的地球化学和技术分析结果。利用x射线荧光（XRF），确定了两个不同的来源：Cerro de las Planicies/Lago Lolog （CP/LL1）和Telsen/Sierra Negra (T/SN1)，均位于巴塔哥尼亚北部和中部，距离研究区约1600公里。研究结果表明，运往乌拉圭的黑曜石点超过了此前南美最远距离的记录，属于世界上最远距离的记录。这些点的技术和形态特征表明了不同的运输、年代、使用和管理轨迹。这有助于更广泛地讨论南美东南部史前社会中异地互动、技术组织、外来原材料的社会和象征意义。

期刊介绍： Quaternary Science Reviews caters for all aspects of Quaternary science, and includes, for example, geology, geomorphology, geography, archaeology, soil science, palaeobotany, palaeontology, palaeoclimatology and the full range of applicable dating methods. The dividing line between what constitutes the review paper and one which contains new original data is not easy to establish, so QSR also publishes papers with new data especially if these perform a review function. All the Quaternary sciences are changing rapidly and subject to re-evaluation as the pace of discovery quickens; thus the diverse but comprehensive role of Quaternary Science Reviews keeps readers abreast of the wider issues relating to new developments in the field.
