ABSTRACT

The aim of this article is to contribute with new information for the understanding of the provisioning strategies of quartzitic raw materials carried out by the hunter-gatherer groups who inhabited the eastern Pampa-Patagonia transition (Argentina) during the Initial late Holocene (ca. 3000–1000 ¹⁴C years BP). To achieve this objective, our study case is focused in Campo Monaldi archaeological locality. Previously proposed provisioning strategies of these raw materials in the study area are re-evaluated. For this purpose, the information provided by the petrographic thin sections of quartzitic rocks, the represented artifactual categories, the weight of transported rocks and the stages of the chaînes operatoires were considered. As a result, two different provisioning strategies are established, suggesting that the hunter-gatherer groups who inhabited the study area during the Initial late Holocene relied on different and complementary mechanisms to obtain quartzitic rocks. In this sense, meanwhile the orthoquartzites of the Tandilia ranges could have been obtained through exchanges, the metaquartzites and quartzite sandstones from the Ventania ranges could have been directly acquired in the outcrops and/or in secondary sources.

摘要

本文的目的是提供新的信息，以帮助了解在全新世初期（约3000年）居住在东部潘帕-巴塔哥尼亚过渡带（阿根廷）的猎人-采集者团体实施的石英原料供应策略。 – 1000 ¹⁴ C年BP）。为了实现这一目标，我们的研究案例集中在Campo Monaldi考古地区。对先前在研究区域中提出的这些原材料的供应策略进行了重新评估。为此，由石英岩的岩石学薄片提供的信息，代表的人工类别，运输的岩石的重量以及沙恩歌剧的阶段被认为是。结果，建立了两种不同的供应策略，这表明在全新世初期晚期居住在研究区的猎人-采集者群体依靠不同的互补机制来获得石英岩。从这个意义上讲，同时Tandilia山脉的原石英岩可以通过交换获得，而Ventania山脉的变石英岩和石英岩砂岩可以直接在露头和/或二次来源中获得。
