Triliths are megalithic monuments scattered across the coastal plains of southern and southeastern Arabia. They consist of aligned standing stones with a parallel row of large hearths and form a space, the meaning of which is undoubtedly significant but nonetheless still unknown. This paper presents a new radiocarbon (14C) dataset acquired during the two field seasons 2018–2019 of the TSMO (Trilith Stone Monuments of Oman) project which investigated the spatial and temporal patterns of the triliths. The excavation and sampling of trilith hearths across Oman yielded a dataset of 30 new 14C dates, extending the use of trilith monuments to as early as the Iron Age III period (600–300 BC). The earlier dates are linked to two-phase trilith sites in south-central Oman. The three 14C pairs collected from the two-phase trilith sites indicated gaps between the trilith construction phases from 35 to 475 years (2 σ). The preliminary spatio-temporal analysis shows the geographical expansion of populations using trilith monuments during the 5th to 1st century BC and a later pull back in the 1st and 2nd century AD. The new 14C dataset for trilith sites will help towards a better understanding of Iron Age communities in southeastern Arabia.

阿拉伯东南部 TRILITH 纪念碑的新放射性碳数据集

Triliths 是散布在阿拉伯南部和东南部沿海平原上的巨石纪念碑。它们由对齐的立石和一排平行的大壁炉组成，形成一个空间，其意义无疑是重要的，但仍然未知。本文提出了一种新的放射性碳（14C) 在 TSMO（阿曼 Trilith Stone Monuments of Oman）项目的 2018-2019 年两个野外季节获得的数据集，该项目调查了 Trilith 的空间和时间模式。对阿曼 Trilith 炉膛的挖掘和采样产生了一个包含 30 个新的数据集14C 日期，将三石纪念碑的使用扩展到铁器时代 III 时期（公元前 600-300 年）。较早的日期与阿曼中南部的两期三石遗址有关。他们三个14从两相三石遗址收集的 C 对表明三石建造阶段之间的差距从 35 年到 475 年（2 σ）。初步的时空分析显示，在公元前 5 世纪至 1 世纪期间，使用三石碑的人口在地理上扩张，随后在公元 1 世纪和 2 世纪回落。新的14Trilith 遗址的 C 数据集将有助于更好地了解阿拉伯东南部的铁器时代社区。
