USGS Publication: Scientific Investigations Map 3172Geologic cross section C–C′ is the third in a series of cross sections constructed by the U.S. Geological Survey (USGS) to document and improve understanding of the geologic framework and petroleum systems of the Appalachian basin. Cross section C–C′ provides a regional view of the structural and stratigraphic framework of the Appalachian basin from north-central Ohio to the Valley and Ridge province in south-central Pennsylvania, a distance of approximately 260 miles.

USGS Publication: Open-File Report 2011–1298
The USGS recently assessed the potential for natural gas resources in the Middle Devonian Marcellus Shale of the Appalachian Basin Province. This preliminary report provides some additional geologic information used in the Marcellus Shale assessment.

Press Release & PublicationIn 2011, the USGS completed an assessment of the undiscovered oil and gas potential of the Devonian Marcellus Shale within the Appalachian Basin Province of the eastern United States. The Marcellus Shale contains about 84 trillion cubic feet of undiscovered, technically recoverable natural gas and 3.4 billion barrels of undiscovered, technically recoverable natural gas liquids according to the new assessment.

Thermal maturation patterns of Pennsylvanian strata in the Appalachian basin were determined by compiling and contouring published and unpublished vitrinite reflectance (VR) measurements.

USGS Publication: Scientific Investigations Report 2010–5152
his report contains a simplified provisional correlation chart that was compiled from both published and unpublished data in order to fill a need to visualize the currently accepted stratigraphic relations between Appalachian basin formations, coal beds and coal zones, and key stratigraphic units in the northern, central, and southern Appalachian basin coal regions of Alabama, Tennessee, Kentucky, Virginia, West Virginia, Ohio, Maryland, and Pennsylvania.
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.
