Abrupt radiocarbon (C) excursions, or Miyake events, in sequences of radiocarbon measurements from calendar-dated tree-rings provide opportunities to assign absolute calendar dates to undated wood samples from contexts across history and prehistory. Here, we report a tree-ring and C-dating study of the Neolithic site of Dispilio, Northern Greece, a waterlogged archaeological site on Lake Kastoria. Findings secure an absolute, calendar-dated time using the 5259 BC Miyake event, with the final ring of the 303-year-long juniper tree-ring chronology dating to 5140 BC. While other sites have been absolutely dated to a calendar year through C-signature Miyake events, Dispilio is the first European Neolithic site of these and it provides a fixed, calendar-year anchor point for regional chronologies of the Neolithic.
在根据日历年代测定的树木年轮的放射性碳（C）测量序列中，突然出现的放射性碳偏移，即三宅事件，为将绝对日历日期分配给历史和史前时期各地未标明日期的木材样本提供了机会。在此，我们报告了对希腊北部迪皮利奥新石器时代遗址的树木年轮和碳年代测定研究，该遗址位于卡斯托里亚湖，是一个被水淹没的考古遗址。研究结果利用公元前5259年的三宅事件确定了一个绝对的、按日历标注的时间，303年树龄的杜松树年轮序列的最后一圈可追溯到公元前5140年。虽然其他遗址已通过碳特征三宅事件被绝对测定到某一历年，但迪皮利奥是欧洲第一个这样的新石器时代遗址，它为新石器时代的区域年表提供了一个固定的、按历年确定的锚点。
