These sediments eventually became the Chickies Formation. [8] Siliclasitc and carbonate deposition continued through the Cambrian and into the Ordovician period. During the Taconic orogeny, more igneous intrusions and metamorphism occurred as the ancestral Taconic Mountains were pushed up.

The Kinzers Formation is a geologic formation in Pennsylvania. It preserves fossils dating back to the Cambrian Period. The base of the Kinzers Formation is primarily a dark-brown shale. The middle is a gray and white spotted limestone and, locally, marble having irregular partings. The top is a sandy limestone which weathers to a fine-grained ...
The age indicated on the most recent geologic map of southeast Pennsylvania shows the Wissahickon being Ediacaran to Cambrian in age. This age is a relative date since the sediments that created the Wissahickon are highly deformed and went through several deformation events.
The Cambrian Hardyston Formation or Hardyston Quartzite is a mapped bedrock unit in Pennsylvania and New Jersey. It was originally described by Wolff and Brooks in 1898, [1] where two outcrops in Hardyston Township, Sussex County, New Jersey, were described.
Stratigraphic range: Cambrian Upper part of the Vintage Dolomite overlain by Kinzers Shale exposed in cut on the Pennsylvania Railroad near Vintage. This is the type section.
The Tuscarora rests conformably atop the Juniata Formation and conformably below the Clinton Group in Pennsylvania. [11] The Tuscarora is a lateral equivalent of the Minsi and Weiders members of the Shawangunk Formation in eastern Pennsylvania, New Jersey, and New York, and of the Massanutten Formation in Virginia, and the Clinch Sandstone ...
