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 ZKoft-com:office:smarttags" />9A01 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.  oft-com:office:office" />
