Abstract

Abstract

Based on the quantitative analyses of abundances of planktonic foraminifera, benthic foraminifera, calcarcous nannofossil and ratios of calcareous and siliceous microorganisms as well as carbonate content in the surface sedimeat of the northeastern South China Sea, it has been found that the carbonate content, the abundance of planktonic foraminifera and calcareous nannofossil, and the ratio of calcareous microorganisms decrease rapidly while the ratio of the benthic foraminifera to the total foraminiferal fauna, ratio of siliceous microorganisms, and the percentage of the agglutinated tests cults indicate that the microfossil abundance and ratio, and the carbonate content are closely related to the carbonate lysocline depth and CCD in the study area.In addition, the carbonate lysocline depth and the CCD are different between the southern and northern areas.The carbonate lysocline depth is deeper in the southern area(2 600 m) than in the northern one(2 200 m).The CCD is 3 600 m deep in the southern area, and 3 400 m deep in the northern one
