华南沿海沙堤十分发育,从闽南至粤、琼、桂四省(区)的海岸多有分布。笔者对百余列沙堤进行了观察,采样,选择了64个样品作年代测定,并收集了前人的35个年代数据,进行了分析研究。试样包括下伏在沙堤之下及沙堤、泻湖内的泥炭、腐木、淤泥、贝壳、珊瑚、海滩岩、贝屑砂岩(作~(14)C测年)以及陶片、石英砂(作热释光测年)。现将该71列沙堤的66个样品年代列如表1,其分布绘成图1。
South China coastal sand embankment is very developed, from Minnan to Guangdong, Qiong, Gui four provinces (autonomous regions) coast are more distributed. The authors observed and sampled over a hundred columns of sand dike, sampled 64 samples for dating and collected 35 previous data from previous generations for analysis. Samples include peat, rotten wood, silt, seashells, coral, beach rocks, boulder sand (for ~ (14) C dating), and pottery, quartz sand (For thermoluminescence dating). The 66 samples of the 71 columns of sand digesters are now listed in Table 1, with their distribution plotted in Figure 1.
