The Ramapo Fault forms the western boundary of the Newark Basin. It is the surface location of the fault between basement blocks of Precambrian bedrock shown in orange. New Jersey, eastern Pennsylvania, and southeastern New York are divided geologically into four physiographic provinces, each distinctive in their

The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
The Passaic Formation is a mapped bedrock unit in Pennsylvania, New Jersey, and New York. It was previously known as the Brunswick Formation since it was first described in the vicinity of New Brunswick, New Jersey. It is now named for the city of Passaic, New Jersey, which is near where its type section was described by paleontologist Paul E ...
