我们对中国与朝鲜接壤的白头山火山东北坡一个褐沸石矿床中采集的两个烧焦树干木材(A和B)进行了加速器质谱学、放射性碳测年和摆动匹配。获得的喷发历年A称为AD945-960，样本B称为AD859-884和AD935-963，范围为2-σ。这些结果无法确定准确的喷发年龄。报告年龄差异的原因可能是由于巨大喷发前的火山气体排放。
We performed accelerator mass spectrometry (AMS) radiocarbon dating and wiggle-matching of 2 wood samples from charred trunks of trees (samples A and B) collected from an ignimbrite deposit on the northeastern slope of the Baitoushan Volcano on the border of China and North Korea. The obtained calendar years for the eruption are cal AD 945–960 for sample A and cal AD 859–884 and cal AD 935–963 for sample B in the 2-σ range. These results are unable to determine the precise eruption age. The reason for the difference in reported ages may be due to volcanic gas emission prior to the huge eruption.
