BEDROCK GEOLOGIC MAP
of
This map is a general overview of the bedrock geology of the state. It is an updated version of Atlas Sheet 40, Geology of New Jersey (Lewis and Kümmel, 1910-1912), and is based on New Jersey Geological Survey (2000). In order to provide a legible map product at this scale, it was necessary to combine many of the units shown on larger scale maps into new units. As a result, some units of small areal extent, small faults and igneous dikes are not shown on this map. This map is not intended to be used as a source of detailed geologic mapping for a particular area; the 1:100,000-scale statewide geologic maps or the 1:24,000-scale geologic quadrangle maps should be consulted.
This 1:250,000-scale map differs from Atlas Sheet 40 in the greater number of geologic units recognized, mainly through regional mapping that was completed from 1985 to 1995, as well as the fact that Quaternary units shown on Atlas Sheet 40 are not depicted on this map. They will be shown on a companion 1:250,000-scale surficial map. The locations of the cross sections are similar on Atlas Sheet 40 to highlight changes in geologic interpretation.
There are a few changes to descriptions of some of the units on this map relative to the 1:100,000-scale map (New Jersey Geological Survey, 2000). The latter is based on geologic mapping completed before 1998, and subsequent work has resulted in nomenclature changes. For instance, unnamed unit at Cape May (upper Pliocene) is now named Stone Harbor Formation (Sugarman and others, 2007), and lower member of the Kirkwood Formation (lower Miocene) is now named Brigantine Member (Sugarman, 2001). There also have been a few changes to the ages of some units. A refinement of the global stratigraphic column (U.S. Geological Survey, 2010) raises the Ordovician-Cambrian boundary and changes the age of the Beekmantown Group from Lower Ordovician to Lower Ordovician and Upper Cambrian and of the Allentown Formation from Lower Ordovician and Upper Cambrian to Upper Cambrian.
