Carboniferous Penultimate period of the Palaeozoic Era, preceded by the Devonian and followed by the Permian. It began about 362.5 Ma ago and ended about 290 Ma ago. In Europe the lower part of the system is termed the Dinantian. It is divided into two series and is characterized by marine limestones with a rich coral-brachiopod fauna.

The main outcrop of Carboniferous limestone in the south Pennines is about 175 square miles (480 sq. km) in extent with several small inliers in younger rocks beyond the southern boundary. Most of the outcrop is in Derbyshire with a small extension into Staffordshire. In striking contrast with the widespread occurrence of bare, fissured limestone sur-

Carboniferous limestone takes form as either a fine-grained calcite mud in ancient shallow seas or as shelly limestone. Shelly limestone forms from layers of crushed coral. Both find use in industry as strong stones for use in roads, cement, and architecture. Caches of limestone from different locations can possess different hardness scores.

Limestone is composed of calcium carbonate from marine organisms such as crinoids, which dominated the seas during the Mississippian Period. Crinoids, commonly called "sea lilies," are delicate animals that typically anchor themselves to the seafloor.

In North America, the early Carboniferous is largely marine limestone, which accounts for the division of the Carboniferous into two periods in North American schemes. The Carboniferous coal beds provided much of the fuel for power generation during the Industrial Revolution and are still of great economic importance.

The area described comprises the south-eastern portion of the Derbyshire limestone massif. A local stratigraphical succession, of Via Gellia Limestones (D1), Lathkill Limestones (D2) and Cawdor Limestones (P2), is established. The subdivisions of the Carboniferous Limestone have unconformable relations with one another.

Castleton has long been known for its Carboniferous Limestone, its caves and for the Blue John semi-precious stone mined here. Much of the area is owned by the National trust and is designated an site of special scientific interest (SSSI). This means that fossils can only be looked at and photographed, but must not be collected.
