| 摘 要： | 运用研制国家铀系年龄一级标准物质的分析测试系统，精确的测定南沙群岛海区诸多柱样的铀含量、沉积物的平均沉积速率，结合相关科学资料综合整理，对比亚南极海等的岩心资料后认为，南沙群岛海域沉积物中自生铀含量（以下简称铀含量）高的层位为冰期，铀含量低的层位为间冰期

| Abstract: | Uranium contents and deposition rates of sediments from many cores of Nansha Islands have been precisely measured with national first grade U series standard materials.Comparing to the relative data of the cores from the Subantarctic and other areas,we believe that there is good correlation between uranium concentration of the sediments and the glacial.The high uranium concentration is associated with the glacial period,and the low uranium concentration is associated with the interglacial period. |

| Keywords: | authigenic uranium concentration of sediments glacial period interglacial period |
