Splits and rolls in underground coal mines – formation and insights, a virtual field trip.

Scott Elrick – Illinois State Geological Survey

Pennsylvanian age coal deposits in the Illinois Basin are part of the most extensive known peat swamps to exist in earth history, once extending from the Appalachians to Kansas. Snaking through these ancient peat environments, contemporaneous river systems provided drainage of the swamps, pathways for sea intrusion during transgressions, and a low lying locus for sediment accumulation. We will take a virtual tour of exposures of coal and associated strata in various underground coal mines in the Illinois Basin, looking at stratal relationships, ‘rolls’ and coal splits, and talk about the dynamic interplay of peat bodies, and erosive and depositional forces at work.
