Image: Bituminous coal (Pikeville Formation, Middle Pennsylvanian; Rt. 15 roadcut north of Jackson, Kentucky, USA) 1

Description: Bituminous coal from the Pennsylvanian of Kentucky, USA. (cross-section view, showing horizontal bedding; ~7.5 cm across at its widest) This is a sample of bituminous coal from a large roadcut north of the town of Jackson, Kentucky. The outcrop has Pennsylvanian-aged cyclothemic sedimentary rocks of the Breathitt Group (formerly the Breathitt Formation). The succession is dominated by interbedded sandstones and shales, with some coal horizons. The latter include bituminous coal and cannel coal (see elsewhere in this photo album). Stratigraphy: float from the Pikeville Formation, Breathitt Group, lower Middle Pennsylvanian Locality: Jackson North outcrop - loose piece from coal bed exposed in the wall above the 1st bench on the southern side of a large roadcut on the eastern side of new Rt. 15, just south of the southbound old Rt. 15-new Rt. 15 split, north of the town of Jackson, north-central Breathitt County, eastern Kentucky, USA (~37° 34’ 51” North latitude, ~83° 23’ 09” West longitude)
