摘要
通过对该区钻孔剖面贡料,结合^(14)C、古地磁、孢粉及微体古生物等资料综合分析研究,对该区第四纪地层提出划分意见和自第四纪晚期以来,地层中存在着典型两期海侵所形成的海相层。
On the basis of lithostratigraphy, combining with comprehensive study of 14C, palaeomagnetism, palynology and micropaleontology, we think the unc-onsolidated deposits in this area are products since Late Pleistocene and mainly formed in Holocene. During this period, marine transgressions affected by palaeoclimate and neotectonic movement occurred many times. Among them there are two transgressions which have obvious regional significance, and happened in late Late Pleistocene and Middle Holocene respectively, with the one in Middle Holocene as the largest on scale.
The lower Holocene bound,classification and the marine transgression stages suggested in the paper can be correlatable in the southeastern coastal areas of China.
