华南地区随着经济建设和科研工作的发展,近年来陆续地取得了一批有关三角洲、海岸带、南海诸岛近代沉积物以及古人类文化遗址的C~(14)同位素年代测定数据。为方便有关单位今后科研工作和生产的需要,本表收集到了1982年为止已公开发表或尚未发表的年代数据,共计272个。其中部份由广东省地震局地质研究室新构造组取得;部份由该组与国家地震局地质研究所张景文、中国科学院地质研究所赵希涛等共同协作所取得;部份引自其他单位的资料。资料按照不同地区编排,资料来源分别在表中加以注明。C~(14)半衰期采用5570年或5568年,少数有*标记者采用5730年,计年起程为1950年。
In recent years, with the development of economic construction and scientific research in South China, a series of dating data of C ~ (14) isotope dating from modern sediments and ancient human cultural sites in the delta, coastal zone and South China Sea islands have been successively obtained. In order to facilitate the relevant scientific research and production needs of the relevant units, this table collected the data of the time of publication or unpublished 1982 till date, totally 272. Some of which were obtained by the new tectonic group of the Geological Research Office of the Seismological Bureau of Guangdong Province and partly by the cooperation of the group with Zhang Jingwen, Institute of Geology, National Seismological Bureau, and Zhao Xitao, Institute of Geology, Chinese Academy of Sciences; some were cited from other units . The data are arranged according to different regions, and the data sources are respectively indicated in the table. The half-life of C ~ (14) is 5570 or 5568. The few marked with * are 5730 and the estimated annual departures are 1950.
