| 摘 要： | 用ＥＳＲ测年方法研究了巢县银山古人类遗址第二、三、四层出土的四种动物牙齿化石的年龄，分别测出其埋藏年龄为２１２、３６１、３６３和４５６千年，由此可推测出第二层出土的古人类化石年龄应在２０万年左右。该结果与古人类学家和古生物学家用铀系不平衡和其它方法得出的结果进行了比较。

| Abstract: | Four tooth samples, collected from the 2nd, 3rd and 4th layer of a paleoanthropological site of Yinshan near Chaoxian are analyzed by ESR dating.Their ages are estimated to be 212ha, 361ha, 363ha and 456ha respectively. The age of paleoanthropological fossils from the 2nd layer is about 200ha, which is in good agreement with the results obtained by U-series dating or other methods for faunal remains as well as the paleoanthropological and paleontological evidence. |
