| 摘 要： | 大荔人属早期智人中较古老的类型 ,在人类起源研究中具有重要意义。采用电子自旋共振 (ESR)测年技术直接测定了采自大荔人所在层位的 3个贝壳样品的年龄 ,同时 ,进行了铀系测年分析 ,根据贝壳ESR的年龄结果 ,大荔人可能老于距今 250ka。 |

| Abstract: | Dali hominid site was discovered in the spring of 1978 at Tianshuigou, Dali county. The human fossil is classified as early Homo sapiens and the site is considered one of the most important paleoanthropological sites in China. ESR technique is used to determine the ages of three shells found in the bed with human fossil. There is later Uranium absorption in the shells and it is considered a kind of absorption in stages. The results of the ages of the shells suggest that Dali hominid may be older than 250ka BP. |
| Keywords: | Dali hominid Shell Electron Spin Resonance (ESR) dating |
