Radiocarbon AMS dating by organic microinclusions in the IW-17 sample from the Batagay yedoma

The dating was carried out at the Laboratory of Radiocarbon Dating and Electron Microscopy, Institute of Geography (preparation of counted matter), and at the Center for Applied Isotope Studies, University of Georgia, United States (direct measurements with an acceleration mass spectrometer). Radiocarbon calibration was conducted employing OxCal 4.3.2 and the IntCal13 curve (Stuiver et al., 2019; Reimer et al., 2013), with ranges rounded off by 5 years. From OxCal v.4.3.2 online.

本测年实验分别于地理研究所放射性碳测年与电子显微镜实验室（负责待计数样品的制备），以及美国佐治亚大学应用同位素研究中心开展，后者采用加速器质谱仪（Acceleration Mass Spectrometer）进行直接测量。放射性碳校正工作借助OxCal 4.3.2软件与IntCal13校正曲线完成（Stuiver等，2019；Reimer等，2013），测年范围以5年为间隔取整，数据来源于在线版OxCal v.4.3.2。
