| 摘 要： | 根据巨葛庄贝壳堤及下伏泥层的有孔虫研究,讨论了贝壳堤底板和下伏泥层各类沉积环境的海面意义,以此作为海面标志点重建的古海面误差范围为±0.225~±0.625m。结合该贝壳堤底板和下伏泥层顶板的年龄数据,重建了3900~3300cal BP时的海面高度为-2.955~-2.715m。

| Abstract: | Taking the foraminifera assemblage variation of the bottom layers of cheniers and the underlying muddy sediments in Jugezhuang Chenier as an example, the authors investigated the sea level indicative meanings of each sedimentary sub-environment at the bottom of the chenier body and the top of underlying muddy sediments. The vertical range of sea level reconstructed based on such indicators is ±0.225~±0.625m. Combined with the ages obtained from both the bottom of chenier body and the underlying muddy sediments, the authors reconstructed a relative sea level at -2.955~-2.715m during the period of 3900~3300cal BP. |
