“…Eastward in the Appalachian Basin, the Colchester was first correlated with the Lower Kittanning coal by Wanless (1939). Subsequent spore analysis confirms that correlation in Ohio and Pennsylvania, as well as with the Princess No.…”

“…Similar groupings were also noted in the Western Interior Basin of the U.S. Midcontinent and eastward into the Appalachian Basin (Wanless and Weller, 1932;Wanless and Shepard, 1936;Wanless, 1939). Basin comparisons indicate a greater percentage of carbonate deposition in the Western Interior Basin and a greater percentage of clastic deposition in Appalachian Basin cyclothems (Wanless and Shepard, 1936;Wanless, 1975aWanless, , 1975bWanless, , 1975cWanless, , 1975dHeckel, 1986, Heckel et al, 1998.…”

The Colchester, Springfield, and Herrin Coals of the Eastern Interior Basin are some of the most extensive coal beds in North America, if not the world. The Colchester covers an area of more than 100,000 km^, the Springfield covers 73,500-81,000 km^, and the Herrin spans 73,900 km^. Each has correlatives in the Western Interior Basin, such that their entire regional extent varies from 116,000 km^to 200,000 km^. Correlatives in the Appalachian Basin may indicate an even more widespread area of Desmoinesian peatland development, although possibly sUghtly younger in age. The Colchester Coal is thin, but the Springfield and Herrin Coals reach thicknesses in excess of 3 m.High ash yields, dominance of vitrinite macerals, and abundant lycopsids suggest that these Desmoinesian coals were deposited in topogenous (groundwater fed) to soligenous (mixed-water source) mires. The only modern mire complexes that are as widespread are northern-latitude raised-bog mires, but Desmoinesian Midcontinent paleomires were topogenous and accumulated within 10° of the paleo-equator.The extent and thickness of Desmoinesian paleomires resulted from the coincidence of prime peat-forming factors, including a seasonally wet paleoclimate; cyclothemic transgressions and base-level rise above extensive, low-relief cratonic areas floored by vast, impermeable paleosols; broad floodplains along large rivers with a groundwater table high enough to hydrologically link peatlands and keep them wet; low, relatively uniform rates of tectonic subsidence; and accumulation in a basin surrounded by low relief, which led to minimal sediment input.

“…1), contains many thin marine limestone beds and shale intervals that are particularly widespread in western areas of the northern Appalachian coal region. The lack of economic coal and overall abundance of "nonproductive" intervals of rocks within the group earned it the formerly applied name "Lower Barren Measures" (Wanless, 1939).…”

“…The Monongahela Group, formally known as the "Upper Productive Measures" (Wanless, 1939) contains several commercial coal beds, the most famous being the Pittsburgh coal bed (Tewalt and others, 2001). Upper Pennsylvanian strata within the Appalachian basin range in thickness from about 650 ft in Ohio (Collins, 1979) to as much as 1,300 ft in West Virginia (Arkle and others, 1979;Edmunds and others, 1979).…”
