Geologic Map of West Virginia. West Virginia's geologic history stretches back into the Precambrian, and includes several periods of mountain building and erosion. At times, much of what is now West Virginia was covered by swamps, marshlands, and shallow seas, accounting for the wide variety of sedimentary rocks found in the state, as well as its wealth of coal and natural gas deposits.

According to the Energy Information Administration, West Virginia is a top coal producer in the United States, second only to Wyoming. West Virginia is located in the heart of the Marcellus Shale Natural Gas Bed, which stretches from Tennessee north to New York in the middle of Appalachia.
The name derives from the Greenbrier River in West Virginia. Greenbrier Limestone is in some places more than 400 feet (120 metres) thick, allowing it to trap large quantities of oil and gas. Since this carbonate rock erodes quickly in the region's wet climate, outcrops are not prominent and are often quarried.
The Bluefield Formation is a geologic formation in West Virginia.It preserves fossils dating back to the Mississippian subperiod of the Carboniferous period.Sediments of this age formed along a large marine basin lying in the region of what is now the Appalachian Plateau.
