8.Palaeogene Biyang fault depressed lacustrine basin experiences four evolutionary phases:foothill flooding depression→sulfate coastal/shallow lake→normal lake→carbonate or sulfate coastal/shallow lake, in pace of this, the evolutionary process of sedimentary wedge is from fluvial fan→steep slope fan delta→gentle slope fan delta→fluvial fan in southern margin which belongs to steep slope zone, and is fluvial fan→delta→fluvial fan in northern margin which belongs to gentle slope zone.
