This paper made lithological combination feature description and grain size analysis of a great number of borehole cores from the new lakeside district of Hefei City, performed depositional system domain division for representative borehole ZK9A01 and plotted the Gunzihe Formation system domain graph.  The study shows that the new lakeside area was of lake facies deposition in the early-mid Pleistocene period, experienced a process from lake expansion to maximum lake flooding and lake shrinking, the lake center was situated southeast of the new district and the favorable area for survey of early-mid Pleistocene aquifers was to the east and southwest of it.
