报道了金牛山古人类遗址5个牙化石样品的ESR和铀系法对比测年结果。两种方法给出相近的23—24万年的年龄值。着重讨论了ESR测年中简单指数拟合求累积剂量的困难、α射线相对效率和氡逸失系数的实验测定以及应如何选择铀加入模式等问题。
The results of ESR and uranium series dating of 5 dental fossil samples from ancient human sites in Jinniu Mountain were reported. The two methods give similar ages of 23-24 million years. This paper focuses on the difficulties of simple index fitting for cumulative dose in ESR dating, the experimental determination of α-ray relative efficiency and the evapotranspiration loss coefficient, and how to select the uranium adding mode.
