    Changes of Sea-level in Fujian Coast During the Past 40 000 Years

    • 摘要: 通过分析福建沿海40 000年以来85个各类海面标志物的古海面高程,发现40~20 kyr BP古海面处于现今海面以下(-25±5)m.末次盛冰期海面大幅度下降,福建沿海为陆相沉积或沉积间断.12 kyr BP海面约为-22 m,晚冰期以来海面快速上升,6.5 kyr BP左右升至现今海面,上升速率为4 mm/yr.早全新世海面位于现代海面之下,大约6.5~6.0 kyr BP出现第一个高海面,达到+1 m左右.6~3 kyr BP海面在(0±5)m波动,3 kyr BP左右出现第二个

       

      Abstract: By analyzing relative sea-level of all kinds of 85 indicators in Fujian coast since the past 40 000 years, we have found the ancient sea-level was below modern sea-level, about(-25±5)m in 40~20 kyr BP. Sea level dropped significantly in the LGM, and it was continental deposits or sedimentary interruption in Fujian coast. Sea-level was about -22 m in 12 kyr BP, and sea level rose rapidly to the contemporary sea-level from the late glacial to about 6.5 kyr BP, around 4 mm/yr. It was below modern sea level in the Early Holocene, appearing the first higher sea level in about 6.5~6.0 kyr BP, around +1 m. Sea level fluctuated between(0±5)m in 6~3 kyr BP, the second higher sea level appearing around 3 kyr BP, about +4 m, and from then on decreased gradually to the current sea level.
