摘    要:对盐城上岗全新世柱状剖面中的有孔虫进行研究,划分出7个有孔虫组合类型。依据组合特征确定盐城地区全新世为潮滩环境,经历了由5次小规模的海水进退构成的海退过程。并且发现潮滩环境下的风暴沉积有孔虫组合中外海分子增多、壳体破损严重,显示出与河口环境的风暴潮有孔虫组合特点的差异。

关 键 词:盐城上岗  全新世  有孔虫  潮滩环境

Abstract:Through the researches on foraminifers in a Holocene columnar section in Shanggang, Yancheng, there are seven types of foraminiferal assemblages. The assemblage characteristics give evidences that Yancheng was in tidal flat environment in Holocene and experienced a regressive process made up of five seawater advance and retreat cycles. It is found that in the assemblages of storm sediments formed in tidal flat settings, open sea species increased and tests were broken, showing the difference from those in the estuarine environment.
Keywords:foraminifer  environment  Holocene  Shanggang of Yancheng
