Abstract

The goal of this study is to report the progress regarding the procurement and circulation of obsidian by hunter-gatherer populations during the Late Holocene in the province of La Pampa, Argentina. A total of 25 samples were analyzed in two stages; in the first stage neutron activation analysis (INAA) was used, while X-ray fluorescence (XRF) was employed in the second stage. This work adds nine archaeological samples from new sites and one from the Lihué Calel obsidian source. The results allow us to take into account the sourcing of the obsidian which was found in archeological sites of four areas of study located in the south and east of the province. Both, the results generated in this new stage, and those previously obtained are integrated and discussed in relation to the information produced by other researchers from the region, which are consistent with the existing ones for La Pampa. They indicate that the obsidian recovered was procured from sources located in the Argentinian and Chilean Andes, as well as the pre-cordillera in the provinces of Neuquén and Mendoza. New data expands the spatial perspective of our interpretations to four new research areas: Curacó basin, Lihué Calel hills, Valles Transversales (Transversal Valleys) and Bajos sin Salida (Endorheic low areas).

阿根廷拉潘帕省黑曜石的采购和流通

本研究的目的是报告阿根廷拉潘帕省全新世晚期狩猎采集人群对黑曜石的获取和流通的进展。共25份样本分两个阶段进行分析;第一期采用中子活化分析(INAA)，第二期采用x射线荧光分析(XRF)。这项工作增加了来自新遗址的9个考古样本和来自lihu Calel黑曜石来源的一个样本。这些结果使我们能够考虑到黑曜石的来源，黑曜石是在位于该省南部和东部的四个研究区域的考古遗址中发现的。这一新阶段产生的结果和以前获得的结果都与该地区其他研究人员提供的信息进行了综合和讨论，这些结果与拉潘帕的现有结果一致。他们指出，所发现的黑曜石是从位于阿根廷和智利安第斯山脉以及内乌克萨姆省和门多萨省的前科迪勒拉地区的来源获得的。新数据将我们的解释空间视角扩展到四个新的研究区域:Curacó盆地，lihu Calel山丘，Valles Transversales(横向山谷)和Bajos sin Salida (Endorheic低地)。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
