摘要
用不平衡铀系法测定了安徽省和县和巢县人化石地点哺乳动物骨化石样品的年代。所得封闭样品的年代值分别集中在15—19和16—20万年范围内。但在两个地点均不排除年代值为二十多万年的骨化石样品存在的可能。所有被测样品均检验了对铀的封闭性。
Seventeen fossil bones and teeth of mammals from the deposits of Hexian and Chaoxian, Anhui Province, where human skull, teeth and occipital bone were found, were dated with uranium series dating method. The closed system of these samples was tested. This paper gives the age ranges of 150-190 ka and 160-200 ka for Hexian and Chaoxian fossil human sites re-spectively. But it can not be excluded that samples (especially, the samples from Chaoxian) with an older age (less than 270 ka) might exist in the lower parts of these deposits.
