摘要

本文以北京顺义高丽营钻孔样品为测试对象

对其石英Ti心ESR信号进行了测试。结果表明

高丽营剖面B/M界限样品的ESR年龄为（861±89）ka

与已知古地磁结果偏差≤10%;用同样方法和参数测试不同深度的高丽营钻孔样品

其ESR年龄随样品深度增加而变老

符合水相沉积序列特征。以上研究结果表明

利用石英Ti心ESR法至少可以获得距今780ka以来的水相沉积物的年龄。

Abstract

For the fluvial sediments older than 200 ka

reliable dating method is yet to be established. ESR is a potential way. In this work

the Matuyama/Brunhes boundary (about 780 ka) samples were collected from the Gaoliying drill

Beijing and the Donggutuo site of the Nihewan basin

Heibei province. Quartz Ti-center ESR signals of the samples were analyzed. The results suggest that the ESR ages of the Matuyama/Brunhes boundary samples are consistent with the ages of paleo-magnetic investigation in deviation of 10%. Meanwhile

measurements of samples from the Gaoliying at different depths were performed. The results suggest that the ESR ages become older with the buried depth. All these indicate the reliability of quartz Ti-center in ESR dating of fluvial sediment

and we can gain the age of fluvial sediment at least younger than 780 ka using quartz Ti-center ESR signal.
