本文介绍了一个更新的大气放射性碳校准从每年层压(纹)沉积物水月湖(LS),日本中部。如前所述,LS纹状沉积物可用于将放射性碳时间尺度扩展到树木年轮校准范围之外,达到11,900 cal BP。我们已经增加了14C测量的陆地宏体化石的密度从同一个核心分析以前。合并后的数据集现在由333个测量值组成,并与其他校准数据进行比较。
This paper presents an updated atmospheric radiocarbon calibration from annually laminated (varved) sediments from Lake Suigetsu (LS), central Japan. As presented earlier, the LS varved sediments can be used to extend the radiocarbon time scale beyond the tree ring calibration range that reaches 11,900 cal BP. We have increased the density of 14C measurements for terrestrial macrofossils from the same core analyzed previously. The combined data set now consists of 333 measurements, and is compared with other calibration data.
