摘要

用电子自旋共振法测得泥河湾地层上部丽蚌－１、丽蚌－２化石样品的年龄分别为１．３６、１．２２Ｍａ根据氨基酸外消法对测得泥河湾地层下部骨化石和丽蚌化石的年龄为２．７、２．９、２．７８Ｍａ等由此可确定河北省泥河湾地层的第四纪时期标准地层的年代。

Abstract

The ESR dating of two clam fossil samples from the upper of Nihewan beds is described. The estimated age is 1.36 and 1.22Ma respectively. Bone and clam fossils bound in lower Nihewan beds were dated by amino acid methods

to be 2.7

2.9 and 2.78Ma respectively. Based on these data

ages of the Quaternary standard strata in Nihewan beds of Hebei Province can be determined.
