Mining in the Goreville Quadrangle
The coal in the Goreville Quadrangle varied considerably in thickness but was characteristically broken by numerous clay shale partings. Immediately above the coal was an erosional conglomerate composed of sandstone pebbles that sometimes channeled into the seam for as much as 6 inches. Few mines are found in this thin, poor quality coal. These mines are poorly located, with no company maps found for any of these mines.
