| 摘 要： | 泻湖是全新世海侵以来发育的以淤积为主的海岸地貌,其沉积地层蕴含了丰富的古环境演变信息.对朝阳港泻湖SO4钻孔岩芯样品作粒度、软体动物、孢粉和14C等项目的测试分析,将该孔地层自下而上划分成陆相、滨浅海相、泻湖相、泻湖-沼泽相等四层和Ⅰ,Ⅱ,Ⅲ,Ⅳ个孢粉组合带.基于对地层和孢粉组合特点的深入剖析,结果表明朝阳港泻湖自全新世海侵以来经历了海湾、沙坝-泻湖和泻湖-沼泽等3个环境演化阶段,同时存在明显的沉积环境和气候变化事件,包括8～7 ka B.P.海陆相之间的不整合沉积间断事件、7～6 ka B.P.的气候暖湿事件和5～4 ka B.P.的明显降温事件.

| Abstract: | Lagoon is the coastal landscape developed by the deposition mainly since Holocene transgression,and the stratigraphic of which contains a wealth of paleo-environment evolution information.Based on the analysis of lithological features,microfossils,sporopollen and 14C dating of the core SO4 samples from the Chaoyanggang lagoon,the stratigraphic of the core is divided into four beds including the con-tinental bed,the coastal bed,the lagoon bed and the lagoon-marsh bed,and the sporopollen zones of the core hav... |
