| Abstract: | The chanier in the north bank of Jiulongjiang Estuary is located in Chonglong, Longha county, Fujian province, PRC. Through composite analysis of its lithology, foraminiferal fossils and sporo-pollen assemblages, the author found that the chanier was composed of three smaller chaniers deposited separately in the same location in 4 300-3800 a. B. P., 2 350-1 870 a. B. P., and 1 300 a. B. P.. The special sedimentary structures of the chanier revealed that the sea levels along the coast or Jiulongjiang Estuary changed three times and fluctuated gradually to its present level during the past 4 300 a. The author also expounded that only the bottom of chanier can exactly be related to the High Water Level. Accoring to this new concept, the author calculated that the heights of the relative sea levels in 4 300 a. B. P.,2 350 a. B. P. and 1 300 a. B. P. were -2.16m, -0.96m and +0.14m respectively. That the absolute sea levels was at variance with the relative sea levels was caused by the tectonics subsidence of the north bank of Jiulongjiang Estuary. |
