Abstract: Some advances have been recorded in the study of sedimentary facies of the Paleogene System in the fault-depressed lake basins in the eastern part of China with the application of seismio facies analysis. Based on the results supplied by relevant parties, the authors have classified the lake basins along the littoral region in eastern China into 5 environmental facies: steep coast, gentle slope coastal region, deep lake region, delta and salt lakes, which, in turn, are grouped into 14 seismio facies, Interpretations are made for each of the corresponding geological facies.
