The Es formation was divided into seven third order sequences based on the seismic, drilling and logging data, and plans deposition system plane distribution maps of different time were plotted by dominance phase principle. The lower Es4 is flood-overlake facies mainly; the upper Es4 is meandering stream and braided river delta deposition above the shore shallow lake background; in the Es3 period, the south mainly developed braided river, meandering stream delta, the northeast area main developed meandering stream delta, the middle area mainly developed semi-deep lakean d deep lake sediments. From lower Es3 to upper Es3, the delta scale gradually increased and the depositional area gradually moved to the east and the southeast; the Es2 period was dominated by shore-shallow lake sediments and widely developed braided river delta and delta deposits; the Es1 period was dominated by shore-shallow lake shoal deposits, and in the south developed meandering stream and braided river delta deposits.The lothological traps of the Shahejie group are mainly fluxoturbidite and stratum lateral pinch-out, and its formation and the distribution of the lothological trap were controlled mainly by the basin structure characteristic, palaeogeomorphology and tectonic activity and so on.

Between 2,500 yr BP and 1,800 yr BP. This was a neo-glacial age with a cold snap. The ice-cap on the King George Island and Ardley Island advanced. Iso -static adjustment lowered the palaeo -first terrace at the edge of Ardley Island under the high tide sea level. This made the rookeries around Y2 lake disappear and Y2 lake changed into a lagoon. The fact of Y2 lake under the sea level was coincident with the radiocarbon age (2180±95 yr BP) of the modern third raised beach terrace with 14m-height above the sea level near Yin ' Ou lake in the Fildes Peninsula.
