Until recently, there was a lack of radiocarbon (14C) dates from the Bronze and Earliest Iron Age (1800–500–1 BC) burial sites in Latvia. The chronology of the sites was assessed on the basis of archaeological analogies with neighboring regions and typological studies of the rather meagre grave inventory. In order to establish a firm foundation for an absolute chronology of burial sites and to better understand changes in mortuary practices during the period, sequences of samples from various burial sites have been dated. In this paper we report 48 14C dates from 12 different sites and discuss them in the context of previously established archaeological chronologies. 14C reservoir effects are addressed: regarding FRE, stable isotope analysis is helpful; however, more data should be gathered in future research. In some cases, the new dates are in accord with previous chronologies, while in other cases some widely accepted assumptions may need to be revised. The new dates have proved false several previous assumptions about both the dates of individual graves and whole sites. Based on the 14C dates, we model the chronological spread of burial barrows in Latvia along waterways, the earliest examples appearing in coastal western Latvia.

重新评估拉脱维亚的青铜器和最早的铁器时代：根据 14C 日期的变化埋葬传统

直到最近，还缺乏放射性碳（14C) 可以追溯到拉脱维亚青铜时代和最早的铁器时代（公元前 1800-500-1 年）的墓地。这些遗址的年代学是根据与邻近地区的考古类比和对相当微薄的墓地库存的类型学研究来评估的。为了为墓地的绝对年表奠定坚实的基础，并更好地了解这一时期太平间做法的变化，对来自不同墓地的样本序列进行了测定。在本文中，我们报告了 4814C 来自 12 个不同的地点，并在先前建立的考古年表的背景下对其进行讨论。14解决了 C 储层效应：关于 FRE，稳定同位素分析是有帮助的；然而，在未来的研究中应该收集更多的数据。在某些情况下，新日期与以前的年表一致，而在其他情况下，可能需要修改一些被广泛接受的假设。新的日期证明了之前关于个别坟墓和整个遗址日期的几个假设是错误的。基于14C 日期，我们模拟了拉脱维亚墓葬手推车沿水道的时间分布，最早的例子出现在拉脱维亚西部沿海地区。
