Seelyville coal: a major unexploited seam in Illinois. Illinois mineral note

Technical Report ·
OSTI ID:5494696
New mapping at the Illinois State Geological Survey has revealed that a major minable coal seam, the Seelyville Coal Member of the Spoon Formation, underlies a large area of eastern Illinois. Although the Seelyville Coal has been actively mined in adjacent parts of Indiana for many years and its presence in Illinois known for some time, its extent in Illinois had not been determined. This study, which principally utilized geophysical logs from oil test holes, shows that the Seelyville Coal may be as much as 3 1/2 to 9 feet thick under an area of approximately 1,900 square miles of Clark, Clay, Crawford, Cumberland, Edgar, Effingham, Jasper, Lawrence, Richland, and Shelby Counties.
