DGS97-2 Surficial Geology of Middlesex County, New Jersey (3.88MB)


DGS97-2 is an ARC/INFO Geographic Information Systems (GIS) coverage of surficial geologic materials of Middlesex County, New Jersey. Surficial materials are the unconsolidated sediments that overlie bedrock or Coastal Plain formations, and that are the parent material for agronomic soils. In Middlesex County, they include stream, wetland, glacial, estuarine, windblown, and hillslope sediments and weathered bedrock material. They are as much as 140 feet thick, but are generally less than 40 feet thick over most of the county. These materials range from coarse gravel to clay and peat. They affect the movement of ground water from the surface into underlying bedrock and Coastal Plain aquifers, and are aquifers themselves in places. They also provide foundation support for structures, and supply sand and gravel for construction projects.

This map was simplified for this display by combining 26 lithostratigraphic units available with DGS97-2 into three units.
