Combined dendrochronology and accelerator mass spectrometry radiocarbon (AMS 14 C) dating analyses were used in order to date an old living tree named Italus , growing in the Pollino massif in Southern Italy. Wiggle match AMS 14 C dating analysis was performed on a 320-yr-long floating chronology obtained by cross-dating four wood cores extracted from the exposed roots of the tree. Following this approach, an age for the tree of ≈1230 yr was estimated. This age makes Italus the oldest living tree in Europe. High-resolution 14 C dating analyses performed on single rings extracted from the tree stem allowed us to identify the 993–994 CE large excursion in atmospheric 14 C concentration (Miyake event) revealing for the first time its presence in the Mediterranean basin.

在欧洲最古老的活树中识别 993–994 CE Miyake 事件
组合的树木年代学和加速器质谱放射性碳(AMS14 C) 使用年代分析来确定一棵古老的活树的年代意大利 ,生长在意大利南部的波利诺地块。Wiggle 比赛 AMS14 C 测年分析是对一个 320 年长的浮动年表进行的,该年表是通过对从暴露的树根中提取的四个木芯进行交叉测年获得的。按照这种方法,估计树的年龄约为 1230 年。这个时代使意大利 欧洲最古老的活树。高分辨率14 对从树干中提取的单个环进行的 C 年代测定分析使我们能够确定 993-994 CE 在大气中的大偏移14 C浓度(三宅事件)首次揭示了它在地中海盆地的存在。
