The top plate illustrates the tectonic setting for the sediments of Pennsylvania. This section is characterized by the metamorphic rocks that provide much of the bedrock for this area. The oldest exposed rocks in Pennsylvania are found here and consist of the Baltimore Gneiss. [8] These rocks have a complex history and a vast array of different ...

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 Pennsylvanian (/ ˌ p ɛ n s əl ˈ v eɪ n i. ən / pen-səl-VAYN-i-ən, [4] also known as Upper Carboniferous or Late Carboniferous) is, on the ICS geologic timescale, the younger of two subperiods of the Carboniferous Period (or the upper of two subsystems of the Carboniferous System).
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.
The extensively thick peat deposit was destined to become one of the most valuable energy resources in the world. The distribution of some of the sediments, particularly the channel sands, may have been controlled in part by deep, Early Cambrian basement faults that were reactivated during the Alleghany orogeny (Root and Hoskins, 1977; Root, 1995).
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 ...
