Geologic cross section I‒I’ is the fourth in a series of cross sections constructed by the U.S. Geological Survey to document and improve understanding of the geologic framework and petroleum systems of the Appalachian basin. Cross section I‒I’ provides a regional view of the structural and stratigraphic framework of the Appalachian basin from the eastern margin of the...

The Appalachian Basin Region is a physiographic province extending from Alabama to Maine and encompasses the eastern seaboard of the United States. Evidence suggests the complex geology of the region was formed by a series of continental plate collisions and deformation resulting in the Appalachian Mountains and large areas of elongated, faulted, and deformed ridges and valleys. Over time erosion has carried sediments seaward to the continental shelf and modified the landscape to the more familiar piedmont terraine. The region contains large amounts of natural resources and a long history of oil, gas, and coal production. The first oil wells in the U.S. were discovered in this province and research and assessments continue on these prolific coal and oil and gas deposits. This web site provides access to the diverse Energy Resources Program research activities and products within the Appalachian Basin Region.
The USGS has completed several assessments of the Appalachian Basin. This information is summarized on the Oil and Gas Assessment Appalachian Basin page.
The National Coal Resource Assessment (NCRA) project was a multi-year effort by the U.S. Geological Survey (USGS) Energy Program to identify, characterize, and assess the coal resources that will supply a major part of the Nation’s energy needs during the next few decades. NCRA data and publications are available on the NCRA Appalachian Basin page.
There are coalbed methane assessments for the Appalachian Basin currently available.
