摘要
据定量分析,发现辐射沙洲海底表层沉积中有孔虫有99种.53属组成.这些有孔虫可划分为4个组合:A.Ammoniabeccarii-Elphidiummagellanicum;B.Ammoniabeccarii-Protelphidiumglabrum;C.Ammoniabeccarii-A.pauciloculata;D.Ammoniabeccarii-Epistominellanaraensis.以有孔虫分布、组成和壳质特征为指示.对研究区的水体特征、泥沙运动及海底动态等作了讨论.
A total of 99 species belonging to 53 genera of foraminifera .found in the bottom sediments takenfrom radial submarine sand ridges along north Jiangsu, can be divided into 4 assemblages: A. Ammoniabeccarii-Elphidium magellanicum; B. Ammonia beccarii-Protelphidium glabrum; C. Ammonia beccarii-A. pauciloculata; D. Ammonia beccarii-Epistominella naraensis.Taking the distribution and composition of foraminiferal assemblages and character of foraminiferal testmaterial as indicators. features of water mass, sediment movment and dynamic state of bottom in the studyarea are discussed as well.
