The Seelyville, Dekoven, and Davis Coals of Illinois, Indiana, and western Kentucky previously were considered separate coal seams of regional extent in the Illinois Basin Coal Field. Subsurface studies reveal that the Dekoven and Davis Coals are, in fact, splits of the Seelyville Coal. A series of seven linked cross sections, with an average of one well per mile, along a 170-mile northeasterly-trending transect in eastern Illinois, western Indiana, and western Kentucky links the type Seelyville Coal at its type area in west-central Indiana with the Davis (No. 6) and Dekoven (No. 7) coals at their type areas in western Kentucky. Geophysical logs constitute the bulk of data utilized in the cross sections. In its type area, the Seelyville Coal contains several shale partings, one of which is fairly continuous but ranges from less than one inch to more than 20 feet in thickness.
