广西合浦独木舟放射性碳定年
Radiocarbon age of canoe from Hepu,Guangxi
【摘要】 为了确定在广西合浦县发现的古独木舟的年代,利用北京大学的小加速器质谱计对4个取自独木舟不同部位的木头样品进行了14C年代测定,结果表明,此独木舟的14C年龄为(365±20)BP.经14C-树轮年代校正曲线校正后,表明独木舟建造的日历年龄在1460~1580 AD(2σ的置信区间).
【Abstract】 In order to confirm the canoe’s age,four wood samples taken from different parts of canoe were measured by a compact accelerator mass spectrometry system at Peking University.The results showed that the 14 C age of canoe was(365±20) BP.With the calibration curve of tree ring,the range in possible calendar dates of building the canoe was from 1 460 to 1 580 AD(within 2σ of conventional values).
