| 摘 要： | 本文以4个钻透上更新统钻孔为例,以岩性和沉积构造为基础,采用“C、微体和孢粉等分析方法,结合气候地层和层序地层学的理论,对渤海湾晚第四纪地层进行了划分,讨论了岩相古地理和新构造特征.渤海湾沿岸晚第四纪地层可以划分为9组地层,自下而上分别为海洋氧同位素5e(MIS5e)、MIS5d、MIS5c、MIS5b、MIS5a、M...

| Abstract: | This paper,taking four drilling holes cutting through the upper Pleistocene as an example to classify the late quaternary strata along the coast of Bohai Bay,discussed lithofacies paleogeography and neotectonic characteristics,based on lithology and sedimentary structures,14C ages of peat and humus mud,micropaleontology and palynology,and the theory of climatic stratigraphy and sequence stratigraphy.Nine units divided are MIS5e(Marine Isotope Stage 5e),MIS5d,MIS5c,MIS5b,MIS5a,MIS4,MIS3,MIS2 and MIS1 in an a... |
