【摘要】 将超灵敏小型回旋加速器质谱计运用于江西瑞昌铜岭古矿冶遗址的14C-AMS测量,并与作者过去的液闪测年结果进行了比较,进一步证明了我国采铜炼铜的规模生产在商代早期就已存在,从而把我国采铜炼铜的历史向前更多还原

【Abstract】 The AMS technique is applied to the dating of the ancient coppermining and smelting relic site in Ruichang, Jiangxi. The comparison is made with the previous liquid scintillation (LC) dating and four data are all coincide within 1～2 σbetween AMS and LC. It proves the reliability of measuring 14C by the home designed minicyclotron based AMS. It is also counterproves that the reliability of both liquid scintillation counter and graphitization sampling process in our laboratory. The measured calendar age is about 1530 B.C., the early Shang Dynasty, which is calibrated by tree ring and is earlier than our previous report without tree ring correction. The results further bring forward the history of copper mining and smelting at this site in China to be 500 years earlier than the previously thought.更多还原
