In early Cenozoic, a rifting phase resulted in the formation of the Fushan Depression and an alluvial fan... angular unconformity [2, 23-24] (Fig. 2). The lake level change is very close to the global sea level change which shows a rapid sea level falling after Middle Eocene and then rising with multi-phase......
