| 説明 | 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.Stratigraphy: Hyden Formation over Pikeville Formation, Breathitt Group, lower Atokan Series (Duckmantian), lower Middle PennsylvanianLocation: Jackson North outcrop - large roadcut on the western side of new Rt. 15, just south of southbound old Rt. 15-new Rt. 15 split, north of Jackson, north-central Breathitt County, eastern Kentucky, USA (37° 34’ 53.95” North, 83° 23’ 07.99” West) |
