Abstract

Dating is one of the most important tasks in archaeology. Studies of elemental composition using neutron activation analysis, combined with statistical data treatment, enable the establishment of indirect dating for the investigated artifacts. In this study, 11 mortar samples were studied. The samples were collected from buildings located on the territory of the Yuryev Monastery (Veliky Novgorod, Russia). For irradiation, the IREN facility at Joint Institute for Nuclear Research (Russia) and the WWR-K reactor at Institute of Nuclear Physics (Kazakhstan) were used. Using neutron activation analysis, mass fractions of 34 chemical elements were obtained. By applying multivariate statistical methods (hierarchical cluster analysis, principal component analysis, and factor analysis), it was established that the elemental composition of mortars from various historical periods differs significantly. This enabled the identification of groups corresponding to specific historical periods. It was shown that the content of rare earth elements in samples dating back to the pre-Mongol period is elevated compared to samples with later dating. The obtained data enabled the classification of samples with unknown dating using the method of indirect dating.

基于中子活化分析数据的尤里耶夫修道院（大诺夫哥罗德）圣乔治大教堂迫击炮

年代测定是考古学中最重要的任务之一。利用中子活化分析对元素组成进行研究，结合统计数据处理，可以为所调查的文物建立间接的年代测定。本研究对11个砂浆样品进行了研究。样本是从位于尤里耶夫修道院（大诺夫哥罗德，俄罗斯）境内的建筑物中收集的。辐照方面，使用了联合核研究所（俄罗斯）的IREN设施和核物理研究所（哈萨克斯坦）的WWR-K反应堆。利用中子活化分析，得到了34种化学元素的质量分数。运用多元统计方法（层次聚类分析、主成分分析和因子分析），确定了不同历史时期砂浆的元素组成存在显著差异。这样就可以确定与特定历史时期相对应的群体。结果表明，前蒙古时期的样品中稀土元素的含量高于后蒙古时期的样品。所获得的数据可以用间接测年法对年代未知的样品进行分类。
