| 摘 要： | 采用岩石地层学、磁性地层学和地球化学等方法,结合TL、ESR和14C等测年,对广泛分布于闽东南沿海的老红砂沉积地层及其形成时代进行了划分。结果表明,该区老红砂沉积地层可综合划分为5个地层段,其中老红砂层可分出3个地层段,分属60~40 ka B.P.、30~25 ka B.P.和20~10 ka B.P.所形成;两个古土层,反映大约在40~30 ka B.P.和25~20 ka B.P.老红砂的发育有过两次较长时间的沉积间断或减弱。

| Abstract: | Based on the analysis of lithostratigraphy, magnetism, geochemistry, and the datings of TL, ESR and 14C, the sedimentary stratum and forming age of the "old red sand" that is widespread in the coastal area of southeastern Fujian Province can be divided into three stages as 60~40 ka B.P., 30~25 ka B.P. and 20~10 ka B.P. |
