摘要: |
介绍ESR测年的基本原理,并讨论风成沙Ge心测年的可行性、风成沙E’心的特征、测年误差及可靠性等问题。1992-1993年在渤、黄、东、南海沿岸采集的100余个风成沙样品ESR测年实验表明,绝大部分海岸风成沙的年龄为1-7万年。 |

Abstract: |
ESR dating was applied on coastal eolian sand collected in 1992-1993. Some problems on the feasibility of ESR dating using Ge center, characteristic of E' center, dating error and reliability of eolian sand are discussed. More than 100 ESR dating experiments on the coastal eolian sand showed that most of their ESR ages are 10-70ka. |
Key words: Coastal eolian sand, ESR, Ge center |
