| 摘 要： | 本文根据3个钻孔岩芯的~(14)C测年数据和微体古生物硅藻的分析结果,对福建沿岸晚更新世末次海侵及其海平面的变化进行了讨论。结果表明,福建沿岸晚更新。世的末次海侵约发生于44000—22000年B.P.间,海水表现为间歇性侵进形式,其中约在39000—34000年B.P.间曾发生一次海水退却。海平面的升降变化与这种海水入侵趋势基本上是一致的,当时的最高海面约出现在30000年B.P.,高度约达—15m。

THE LAST MARINE TRANSGRESSION AND SEA LEVEL CHANGES ALONG THE FUJIAN COAST DURING LATE PLEISTOCENE |
| |
| Abstract: | Radiocarbon dates and micropaleontological analyses of diatoms in three boreholes show that the last marine transgression along the Fujian Coast during Late Pleistocene took place intermittently between 44,000a B. P. and 22,000a B. P., with a regression between 39,000a B. P. and 34,000a B. P. Sea level movements were consistent with the transgre-ssive trend of sea water. The highest eustatic sea level occurred at approximately 30,000a B. P. when sea level attained an elevation of about -15m. |
