Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.Above the shale and limestone is a gravel deposit that was laid down not much over 100 thousand years ago, during the waning stages of Illinoian glaciation during the Ice Age. The line of contact between the gravel deposit above and the shale below thus represents a time gap of immense duration. Such a time-loss line is called an hiatus.

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. The shale is overlain by a light-brown, fossiliferous limestone about 1 foot thick. Overlying this limestone is a thin, gray, clayey shale that is overlain by a thin, tannish-gray limestone encrusted with algae.

Gray limestone and fossiliferous shale interbedded with greenish gray graywacke or litharenite. Laminations and graded bedding. Fossils in the shale and limestone consist primarily of molds of brachiopods. delta. continental slope and rise. alluvial fan. fluvial. swamp. lacustrine. lagoon. barrier beach. desert. abyssal plain.Fossiliferous – Fossils are present If your rock meets all of those criteria then it is a shale, or at least something very closely related. Remember that not all shales contain fossils, and that some of them are well-cemented enough so as not to be fissile.
