The site of Nokalakevi, in western Georgia, has seen significant excavation since 1973, including, since 2001, a collaborative Anglo-Georgian project. However, the interpretation of the site has largely rested on architectural analysis of standing remains and the relative dating of deposits based on the study of ceramics. Since 2013, the Anglo-Georgian Expedition to Nokalakevi has collected a diverse dataset derived from multiple scientific techniques including optically stimulated luminescence (OSL) dating of ceramics, radiocarbon dating, δ13C and δ15N analysis and 87Sr/86Sr analysis. The full results of these analyses are reported here for the first time along with implications for the interpretation of the archaeology, which include greater detail in the site chronology but also indicators of diet and migration.

近期科学技术对佐治亚州萨梅格雷洛 Nokalakevi 研究的贡献

自 1973 年以来，佐治亚州西部的 Nokalakevi 遗址进行了重大挖掘，其中包括自 2001 年以来的英格-格鲁吉亚合作项目。然而，对该遗址的解释主要依赖于对站立遗迹的建筑分析和基于陶瓷研究的沉积物的相对年代。自 2013 年以来，盎格鲁-格鲁吉亚诺卡拉克维探险队收集了来自多种科学技术的多样化数据集，包括陶瓷的光激发发光 (OSL) 测年、放射性碳测年、δ13C和δ15N分析和87锶/86先生分析。此处首次报告了这些分析的全部结果以及对考古学解释的影响，其中包括更详细的遗址年表以及饮食和迁移指标。
