English: Hyden Formation over Pikeville Formation in the Pennsylvanian of Kentucky, USA.
This is a relatively new roadcut along new Route 15, north of the town of Jackson, Kentucky, USA. The exposure has Pennsylvanian-aged cyclothemic sedimentary rocks of the Breathitt Group (formerly the Breathitt Formation). The upper part of the roadcut is Hyden Formation, consisting of mixed siliciclastics and coal. The lower part is Pikeville Formation, also having mixed siliciclastics and coal. Coal beds are principally bituminous coal horizons, but there is one cannel coal horizon in the upper Pikeville Formation (= approximately half-way up the cut, right below a relatively thin, light-colored sandstone interval).
