摘要:
通过对南黄海辐射沙脊群兰沙洋潮流通道07SR09孔的沉积相分析及粒度、14C测年、有孔虫鉴定、磁化率等实验指标的测试结果分析,并结合区域文献和钻孔数据资料分析,研究了兰沙洋潮流通道晚更新世以来的沉积环境演化特征。晚更新世时,古长江曾在此流入南黄海,粒度测试结果表明,自晚更新世至今,因古长江逐渐南迁,古长江源的细砂含量也呈逐渐减少趋势。结合前人相关文献分析,推测本孔所处区域在古长江南迁后受到了后期物源在此沉积的影响,很可能是古黄河源物质,也有可能是潮流作用带来的较细颗粒在此沉积,这些后期沉积的较细颗粒在一定程度上“稀释”了本区的沉积物粒级构成。而据磁化率实验测试结果分析,并结合有孔虫种属分布及数量特征,揭示出自晚更新世以来,兰沙洋潮流通道的水动力变化环境渐趋稳定,可以作为优良的天然深水航道。
Abstract:
The Lanshayang tidal channel is one of the major tidal channels in the radial sand ridges area of the South Yellow Sea. The evolution of sedimentary environment of the channel since the late Pleistocene is studied based on regional literature review and core data analysis. The analysis of core 07SR09 in the channel includes sedimentary facies, grain size, 14C dating, foraminifera identification, and magnetic susceptibility.
The paleo Yangtze River flows into the South Yellow Sea since the late Pleistocene. The results of grain size analysis show that the content of fine sand was decreasing because of the southward movement of the paleo Yangtze River. We argue that this area was influenced by deposition after the southward movement of the paleo Yangtze River, most likely from the paleo Huanghe River, or the finer particles brought by tidal action. And these later deposited fine particles diluted the original sediment grain size composition of this area. According to the analysis of magnetic susceptibility, and the distribution of foraminifera species and quantitative characteristics, the hydrodynamic conditions of the Lanshayang tidal channel have become steady gradually since the late Pleistocene, and the tidal channel is excellent for a natural deepwater channel
