| 摘 要： | 长江三角洲地区晚新生代以来接受了大量沉积，长时间序列沉积地层研究对于三角洲沉积环境演化和长江变迁历史都具有重要研究意义。通过对长江三角洲DY03孔古地磁、磁化率以及岩性分析，初步建立了研究钻孔较为可靠的年代地层框架。研究发现，长江三角洲地区沉积序列中有多个具有全球对比意义的短时期磁性漂移事件，对磁性地层定年的进一步应用具有重要意义。分析表明，研究区晚新生代地层中普遍发育的硬黏土层不仅是晚第四纪地层对比的重要标志层，而且对整个晚新生代以来的沉积地层对比都会发挥重要作用。长江三角洲沉积演化基本呈现出早期受构造活动控制，后期受海平面升降和气候变化的制约。 |

| Abstract: | A large amount of sediment has been deposited in the Yangtze River delta area since the late Cenozoic,which has important implications for long-term research of sedimentary environmental evolution and changes of the Yangtze River.With methods of paleomagnetism,magnetic susceptibility and lithological analysis,a reliable chronostratigraphic framework of core DY03 in the Yangtze River delta was established.It is found that there are several short term magnetic excursion events which have global significance r... |
