Carboniferous Limestone - Wikipedia

Carboniferous Limestone is a collective term for the succession of limestones occurring widely throughout Great Britain and Ireland that were deposited during the Dinantian Epoch of the Carboniferous Period. These rocks formed between 363 and 325 million years ago. Within England and Wales, the entire limestone succession, which includes subordinate mudstones and some thin sandstones, is known as the Carboniferous Limestone Supergroup. Carboniferous Limestone | S-cool, the revision website,Carboniferous limestone features /**/ Carboniferous limestone produces distinctive karst scenery. These areas are dry on the surface due to the permeability of the rock, but have mainly been shaped by the action of water. The water attacks the many joints and bedding planes in the rock, through the chemical weathering processes of carbonation,Carboniferous_limestone - chemeurope,Carboniferous Limestone is a type of limestone rock, which was laid down in Great Britain and Ireland in the Dinantian stage of the Carboniferous period.It was formed between 363 and 325 million years ago. It is one of the three most common types of limestone found in Britain, along with chalk and Jurassic limestone.

Chalk - Wikipedia

Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of sub-microscopic plankton which had fallen to the sea floor.Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the,Great Elm and Vallis Vale | Locality areas | Foundations,,These quarries, developed in the Carboniferous Limestone supplied rock mostly for roadstone, but also for lime production.
