Geological Problems Reported

The roof for the Herrin Coal was sometimes the Brereton Limestone, which was generally 1 to 2 feet thick but locally up to 4 feet thick. In 36-T9N-R5E, the Herrin Coal was heavily affected by “whitetop”, a light gray clay material, and the thickness was highly variable. The white top material infiltrated the upper portion of the seam. This problem decreased downward in the coal, but made a very dirty product. Slip planes and cracks in the coal were observed, as well as clay dikes. The top of the seam was irregular. The blue band was about2 inches thick in this area. Pyrite lenses up to 1.5 inches were noted, as were pyrite nodules.
