MARGIN: 0cm 0cm 0pt" class=MsoNormal>The present paper gives a detailed description, on the basis of cores, well logs and regional geological background, of the sedimentary facies and evolution of the second member of the Palaeogene Dainan Formation in the deep area of eastern Gaoyou Depression, ml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />me w:st="on">Northme> me w:st="on">Jiangsume> Basin. The second member of the Dainan Formation consists of the fan delta facies, delta facies and lacustrine facies. On the whole, the water bodies displayed the shallow-deep-shallow variations during these periods. The retrogradation occurred first in the fan delta and delta facies, followed by the progradation. At the latest stage, the lake basin was subjected to the uplift and erosion, which resulted in the unconformable contact with the overlying strata.ml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
