摘要 本文测定了银山地点钟乳石和骨化石样的铀系年代.根据位于第2层顶部一钙板样3次分析的平均值,巢县人的上限年龄应为31万年,据此似可将这一人类化石从目前分类的早期智人改划为晚期直立人.讨论了钟乳石铀系年代的可信度.银山下部地层骨化石样的分析结果,可引为二法一致的骨化石铀系年龄不足以保证数据真实的例证. The chronological position of the paleoanthropological site of Yinshan in Anhui Province, East China, was re-examined by applying U-series dating to stalagmitic carbonate and fossilbone samples. Judging by the result of a stalagmitic sample taken from a travertin layer abovethe hominid fossil containing 2nd layer, Chaoxian Man should be older than 310 ha. It seemstherefore possible to re-arrange it into the category of late 'Homo erectus' instead of formerly accepted classification of early 'Homo sapians'. The reliability of the U-series age of stalagmitic carbonate has been discussed. The results of two fossil bones taken from the lower strata of the site, assigned to Early Pleistocene by the existence of several Tertiary survivals, may be cited as an evidence that consistancy between the results of two U-series methods does not necessarily guarantee its validity.
