据太湖827孔微体古生物群生物相分析,并参考古地磁、~(14)C测定、计算机模拟实验结果,本文报道了该孔海侵层的研究.由于该孔是目前中国东部沿海平原采样最密的钻孔,因而,得以在其中布容极性期里发现七个厚薄不等的、含海相微体化石的层段(或层位).它们大多为泻湖相沉积.其中最新的海侵层形成于3万余年前,接近其中部的层位见晚更新世暖水种化石.本文倾向认为:苏州东山渡村一带没有全新世海侵层沉积.
According to the analysis of the biofacies of the 827 well microprobe paleontology group in Taihu Lake and the reference of the paleomagnetic and ~ (14) C measurements and the computer simulation results, this paper reports the study of the pore and sea invasion.As the hole is currently sampling in the coastal plain of eastern China The most dense boreholes, therefore, allow for the discovery of seven intervals (or horizon) of marine-facies microfacies within the polar period of the cloth, most of which are lacustrine sediments, the most recent of which The marine formation was formed more than 30,000 years ago and the late Pleistocene warm-water fossils near the middle of the sea layer were seen in this paper.It is suggested that there is no Holocene transgression sediment in Dongshandu Village, Suzhou.
