The Study on Diatom of Late Quaternary Sediment in the Continental Margin of the East China Sea (Northern Fujian Member)

WANG Kai-fa; ZHI Chong-yuan; ZHENG Yu-long; WANG Hong-gen

The sediment of 4 well's cores of late Quaternary at the continental margin of East China Sea have been systimatically researched, and abundant fossils of diatom, 117 species and varieties in 33 genus, have been found. 12 of diatom zones have been divided according to the characteristics of the diatom pattern, theoptimac Sparation and the corresponding order.They are from buttom to top: 1. Cascinodiscus argus-Cos. wittiomus-Cyclotella striata,2. Cos. blandus-Cyclotella striata diatom zone,3. Cos.excenfricus-Trbliepteychus cocconiformis diatom zone,4. Gomphonema-Cos. blandus-Actnolychus ralfsii diatom zone,5. Cos.-Cyclotella striata-Actinocyclus ralfsii diatom zone,6. Cos. -Actinolychus ralfsii diatom zone,7. diatom poor zone,8. Cos. lineatus-Cos. rothii-Actinolyclus ralfsii diatom zone,9. Gomphonema-Cyclotella striata-Cocconeis placentula var euglypta diatom zone,10. Cos.rothii- Cyclotella striata-Actinolychus ralfsi dialom zone,11.Cymbella affinis-Cyclotella striata-Gomphonema diatom zone,12. Coscinodiscus wittinus-Cyclotella striata-Epithemia hyndmanii diatom zone. Diatom assemblage order patterns of late Quaternary has been set up and the palaeoenvironment evolvution is discussed.
