摘要：

Analyses of foraminiferal fauna in the core np93-2 of the prydz bay,Antarctica shows that the sediments are rich in foraminifera in which planktonic Foraminifera make up 26.3% of the total number of foraminifera and the arenaceous Agglutinated benthic foraminiferal assemblages are prevailing with 57.9% of total Number of benthic foraminifera. The typical benthic foraminiferal assemblage of Iammina arenacea represents an assemblage of deep-water arenaceous agglutinated.Variations of content of warm and cold species of planktonic foraminifera reflect the Paleoclirnatic changes and also reveal the paleo-environmental changes in this region andIts relationship with the global changes. Other paleoceanographic and Paleoclimatological questions, such as water depth, carbonate dissolution are also discussed.
