Green, silty, glauconitic and fossiliferous shale occurs at the core of all Fort Payne buildups (Fig. 1). Krause and Meyer (2004) combined green shales within mounds with green-gray shales above the mounds into the same facies, but herein the shales are subdivided as a separate facies similar to (but slightly different from) the green shale …Shale and interbedded limestone. Shale is gray, green, red, reddish brown, or maroon, sandy, calcareous, fossiliferous, locally fissile; several fissile black shale beds are in lower 75 feet. Interbedded dark- to light-gray, medium- to thick-bedded, argillaceous, cherty limestone beds are very fossiliferous and locally contain shale partings.

In zone LMX-3, the mixed shale shows relatively well-developed lamination, with generally light-colored detrital silt laminations interbedded with dark laminations composed of clay, organic matter, pyrite and some detrital grains. In addition, graptolites are abundant along the shale bedding planes, forming fossiliferous layers (Fig. 14 aSedimentary Rocks. Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water. These particles and chemicals come from the weathering (breaking apart in place) and erosion (carrying away and breaking apart while moving) of rocks on the Earth’s surface.1-7.
