Summary[edit]
DescriptionBituminous coal (Washington Coal, Upper Pennsylvanian; Narrows Run South roadcut, near Powhatan Point, Ohio, USA) 2.jpg |
English: Bituminous coal from the Pennsylvanian of Ohio, USA. (cross-section view; ~11.6 cm across)
Coal is a carbon-rich, biogenic sedimentary rock. It is not composed of minerals - it has macerals of various types of organic matter. Coal represents buried, compacted, and altered peat deposits from a swamp environment. The sample shown here is bituminous coal, a common type of coal. It is a higher rank coal than lignite and a lower rank coal than anthracite. Bituminous coal has blocky weathering and is moderately sooty to the touch. Stratigraphy: float from the Washington Coal, lower Washington Formation, lower Dunkard Group, Upper Pennsylvanian Locality: Narrows Run South Outcrop - upper part of large roadcut on the western side of Rt. 7, immediately south of Narrows Run, north of the town of Powhatan Point, next to the Ohio River, Belmont County, Ohio, USA (39° 54' 06.70" North latitude, 80° 48' 38.80" West longitude) |
