| 摘 要： | 在对长江三角洲南部平原5个钻遇基岩的晚新生代钻孔的地层、岩性、粒度分析的基础上,根据各岩心剖面中湿生、水生植物花粉和外来植物桫椤孢子化石的分布特征,阐述该区新近纪晚期以来沉积地貌环境演变过程,从而为长江演化的研究提供新的思路.结果显示,新近纪沉积物为粗细混杂的洪积扇相,缺乏湿生、水生植物花粉,反映了此时研究区古地势东西...

| Abstract: | The present study examined the stratigraphy,lithology,and pollen-spore,especially the diagnostic pollen-spores of the wetland plant,aquatic plant and Cyathea from 5 Late Cenozoic boreholes drilled in the southern Yangtze delta plain,aiming to reveal the sedimentary geomorphological evolution since the Neogene and give insight to the studies of the Yangtze catchment evolution.The results demonstrate that the very poorly-sorted,wetland pollen-lacked sediments were formed as alluvial fan in the Neogene,when to... |
