| 摘 要： | 北京延庆盆地是一个小型的新生代断陷盆地，第四纪时期曾发育多期湖相层，而对这些湖相层的时代有着不同的认识。应用电子自旋共振（ＥＳＲ）测年方法对采自北京延庆盆地地表湖相沉积层的６个钙质样品作了年龄测定，结果表明，延庆盆地地表出露的较老湖相层的时代属于中更新世

| Abstract: | The Yanqing faulted basin has been developed since the late Cenozoic.It is confirmed that there are lake Quaternary sediments in the basin.ESR technique was used to date samples of the caliche in lake deposit exposed on the surface from the Yanqing basin, Beijing.The results indicate that it is possible to date caliche by using ESR technique,and the estimate of age for the lake deposit in question has been conducted. |
