摘　　要：本文报道浙江桐庐人头骨新生碳酸盐岩外模的alpha能谱和质谱法铀系年代。结果表明其年代很可能介于 0 5— 1万年间。U-series age determinations using conventional alpha spectrometry and high-precision mass spectrometry were carried on calcite outer cast of the hominid skull recovered from a cave in Tonglu County, Zhejiang Province. The results suggest a time period between 5 and 10ka as the best age estimate for this fossil hominid.
