DescriptionCannel City-Amburgy Coal Zone (between channel sandstones, Pikeville Formation, Middle Pennsylvanian; Jackson North roadcut, Breathitt County, Kentucky, USA) 3 (17005640795).jpg |
Cannel City-Amburgy Coal Zone in the Pennsylvanian of Kentucky, USA. This exposure is part of 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). Shown above is the Cannel City-Amburgy Coal Zone. The two black-colored horizons are coal beds. The upper coal bed is cannel coal. The lower is bituminous coal. Cannel coal is a scarce, fossil spore-rich variety of coal - it is hard, has a velvety to satiny luster, little to no stratification, and a conchoidal fracture. Bituminous coal is a common variety of coal - it is relatively soft, sooty, has blocky-weathering, is well stratified and laminated, and has patches of glassy-lustered material (vitrain) in and among dull-lustered material. The cannel coal horizon was economically significant in the early 20th century, and the unit was extensively mined in eastern Kentucky. Published info. about the locality shown above (see Greb & Eble, 2014) indicates that the cannel coal is 33% ash and 1.6% sulfur. The macerals in the cannel coal include liptinite (~47%), inertinite (~31%), and vitrinite (~22%). Plant microfossils from the cannel coal are principally lycopsid tree spores and calamite sphenophyte spores. The cannel coal horizon itself represents an ancient lake formed in a basement fault-generated depression. The grayish, cliff-like unit at the top is a channel sandstone. The gray to brown unit between the two coal horizons is shale. The unit at the bottom of the photo is another channel sandstone.
