| Abstract: | In the researches of coastal and sea-level changes during the last few years, the authors collected more than 100 published and unpublished 14C dates of the past 6000 years along the Fujian Coast, of which, 35 14C dates with accurate altitude and age, and with clear relation to sea level were selected to study sea-level changes in this paper. Through serious evaluation of these 35 14C dates, a sea-level curve of the past 6000 years along the Fujian Coast has been established.
The curve indicates that sea level along the Fujian Coast has been fluctuating around its present position since the past 6000 years. The highest and lowest stands of sea level occurred about 5000 years B. P. and 4000 years B. P. with altitudes of about +2m and -2m respectively.
The general trend of sea level changes during the past 6000 years along the Fujian Coast reflected by this curve is consistent with those along the coasts of Mauritania of Africa and Bahia, Brazil of South America. It is evident that this similarity in sea-level changes among the different continents has an important significance in sea-level studies. |
