| 摘 要： | 于１９９０年５－６月在永暑礁坪上打一全采芯的地质研究钻井，编号为南永１总进尺为１５２．０７ｍ，对岩芯详细的地质年代学，地层学，相学和岩石学等进行多学科的分析研究，结果表明，永暑礁地区的海平面自早更新世晚期以及经历了４次上升和间隔的３次下降，形成了４个沉积旋回及其间的３个沉积间断。海平面呈波动式上升趋势。

| Abstract: | During May and June, 1990, a geological research core at Yongshu Reefflat named core Nanyong-1 (152.07m deep) was drilled. According to the detailedand multidisciplinary data of geochronology, stratigraphy, facies and petrology ofcore Nanyong- 1, the changillg curve of sea-level of Yongshu areas since 900000years B.P. was drewed. Analytical result showed that the sealevel had 4 rises and 3falls intermediately since late stage of Early Pleistocene, and formed 4 sedimentarycycles and 3 sedimentary interruPted surfaees. Generally, the sea-level rose fluctuatedly. |
