滦河口地区有孔虫、介形虫的分析

AN ANALYSIS OF FORAMINIFERA AND OSTRACODA FROM THE AREA OF THE LUANHE RIVER MOUTH

本文应用滦河口地区沉积物中的有孔虫、介形虫的分析结果,探讨了不同沉积环境中有孔虫、介形虫的组合特征及其与环境的关系。根据生物组合和生物自身变化特征,并参考所处地貌部位及沉积物性质,对该区进行了地层对比和古环境分析。

Based on the analysis of the Foraminifera and Ostracoda from the area of the Luanhe River Mouth,the distributions of Foraminifera and Ostracoda,the environmental factors influencing them and the changes of the ancient geography shown by assemblage of Foraminifera and Ostracoda have been studied in the peper.It is shown that the Foraminifera and Ostracoda have obvious differences in their assemblage in different facies.The change of some environmental factors influences the distribution of the assemblage of Foraminifera and Ostracoda Therefore,in making stratigraphic correlation and analysis of the paleoenvironment of the area of the Luanhe River Mouth,the features of sediments may also serve as an important reference beside the characteristics of assemblage of Foraminifera and Ostracoda and the changes of the origanisms themselves.
