The Ongamira Valley (Córdoba, Argentina) shows a persistent occupational history of its territory. Even one of the first Argentinian radiocarbon (14C) dates was calculated in this valley; for 70 years, the chronology was based on relative dates (stratigraphy and its cultural content). For this reason, since 2010 a 14C dating program has been developed focusing on the chronology of eight of the 60 sites identified so far for the valley. This work reports the outcomes of this program with 27 new dates. These data have been related to characteristics of the material culture, use of space and mobility of hunter-gatherer societies. The results have allowed us to bring new insights into a continuous occupation of the valley since the Middle Holocene according to the human peopling models proposed. It has also been possible to provide greater chronological precision to various activities related to feeding practices, use of space associated with rock-shelters, palaeoenvironmental changes and incorporation of new technologies into daily practices.

中新世和晚全新世期间阿根廷中部人类活动的新放射性碳证据:ONGAMIRA VALLEY 案例

Ongamira 山谷(阿根廷科尔多瓦)展示了其领土上持续的职业历史。甚至是阿根廷最早的放射性碳之一(14C) 在这个山谷中计算日期;70 年来,年表是基于相对日期(地层学及其文化内容)。为此,自 2010 年14已经开发了 C 测年程序,重点关注迄今为止为山谷确定的 60 个地点中的 8 个地点的年表。这项工作以 27 个新日期报告了该计划的结果。这些数据与物质文化特征、空间利用和狩猎采集社会的流动性有关。根据提出的人类模型,这些结果使我们能够对自中全新世以来对山谷的持续占领带来新的见解。还可以为与喂养实践、与岩石庇护所相关空间的使用、古环境变化以及将新技术纳入日常实践相关的各种活动提供更高的时间精确度。
