Fossiliferous shale

This upper contact is most likely shale on shale so is diffi

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.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 Bibb County and southwestern Shelby County, the Conasauga consists of medium-bluish-gray fine-grained, thin-bedded argillaceous limestone and interbedded dark-gray shale. In the eastern Valley and Ridge the lower part includes dark-green to pale-olive fossiliferous shale with a few dark-gray limestone interbeds.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.the fossiliferous sediment in BIIc8 (15) (BK 457b, 118.2 m) showing subaerial exposure feature and little to no compaction of fossiliferous dolomitic shale.

Recent Examples on the Web Alas, quarrying explosives had blown apart the fossiliferous layers of rock, splintering many of the bones. — Gemma Tarlach, Discover Magazine, 19 Dec. 2018 The material came from the famously fossiliferous Aust Cliff, and, like the Somerset specimen, is from the Late Triassic's Rhaetian Age, about 201-208 million ...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."Fissile" means that the rock readily splits into thin pieces along the laminations.
